In-house AI storage has supported our NAS workloads and provides solid performance and integration
Pros and Cons
  • "We have been using it for a little while now, and what we have seen is that the NAS performance is quite good, and the ones we are using for data integration and AI factory are working very well as well."
  • "The previous versions do not support features like object storage; S3 and better cloud connectivity are things I would like to see."

What is our primary use case?

One of our use cases for Dell PowerScale is to have a storage system for us. We are basically using it for hosting our NAS and as shared storage. We also have a couple of servers for our AI factory, which is still in POC with the NVIDIA GPU. Compute is our primary focus at the moment.

We are not using Dell PowerScale for data management at the moment; perhaps in the future, we might use it as a warehouse or for some other use, but currently it is just a NAS that we are using to store our databases locally, and those databases are not that operation-intensive.

Dell PowerScale does play a role in our organization's AI initiatives. It is still in POC, but it does contribute to our efforts.

What is most valuable?

We chose Dell PowerScale because we already had Dell management, so we know the hardware is solid and it comes with NVMe SSDs. The IOPS is there, and we were looking for use cases to build our own in-house generative AI. The contenders were either using Cisco UCSX or going with Dell PowerScale. Since our whole environment was already Dell PowerScale, we went with Dell. Additionally, there is also integration with OEM, which makes our lives much easier and we can have a single point of focus.

The integration of Dell PowerScale with our existing IT infrastructure is pretty efficient for operational efficiency. We have been using it for a little while now, and what we have seen is that the NAS performance is quite good, and the ones we are using for data integration and AI factory are working very well as well. OEM integration is there, which makes our lives much easier.

What needs improvement?

The previous versions do not support features like object storage; S3 and better cloud connectivity are things I would like to see. A policy-based management system would also be much better.

For how long have I used the solution?

I have been working with Dell PowerScale for more than two years now.

902,270 professionals have used our research since 2012.

What do I think about the stability of the solution?

Till now we have not seen any issues with the overall operational efficiency and ease of use of Dell PowerScale. We are running somewhere around 500 TBs on each server, and we have not faced any issues with IOPS or network connectivity.

In terms of performance and reliability, we have not had much experience with complex data sets; we are still using it for basic NAS purposes. Whatever we have done so far, we have not seen any issues. We have not had any hardware failure yet, so we do not know what kind of redundancy or failures to expect in the future. At the moment, it is quite stable, as are the other servers from Dell.

What do I think about the scalability of the solution?

Dell PowerScale seems scalable as it uses OneFS. While I am not entirely sure what kind of enterprise data protection and compatibility it will have in the future, it seems scalable for us at the moment.

How are customer service and support?

Regarding the technical support and customer service teams, from what we have seen, Dell tech support is quite good and on point; we do not have any complaints. On a scale of one to ten, I would rate Dell tech support as a nine or ten; the support is there for us anytime we need it.

Which solution did I use previously and why did I switch?

For our AI practices, we did not use a different product prior to adopting Dell; it is a really new initiative for our team and our product. We were using PowerEdge and also using EMC, though.

How was the initial setup?

The initial setup process of Dell PowerScale is quite straightforward; everyone has worked on Dell before. The UI was familiar even though a couple of changes were made, but it was not that difficult for us.

What about the implementation team?

We did the deployment in-house.

What was our ROI?

We have not had trouble managing aspects like AI-driven data insights and automation with Dell PowerScale; since it supports RDMA and RoCE version two, that is one of the great things we have. Additionally, NVIDIA GPUs are integrated with that, and I would have to go more in-depth since we are using a couple of custom software solutions, and that can be a violation for me.

What's my experience with pricing, setup cost, and licensing?

I do not know what the purchase price was as I am not included in the budgeting discussions. From what I know about the physical racking, stacking, and everything, it seems to be quite efficient at the moment. However, we acquired it a couple of years ago, and we just recently started, so I am not sure what the current price point is in the global market.

Which other solutions did I evaluate?

The contenders were either using Cisco UCSX or going with Dell PowerScale. Since our whole environment was already Dell PowerScale, we went with Dell.

What other advice do I have?

We work with Dell EMC and then we have Dell PowerEdge. We do work with Dell PowerScale.

We have not had cloud-based operations; however, we have done it with Dell PowerEdge. From my experience with Dell, it works fine. We are using a couple of servers with an open-source OS for our edge routers, and it just works fine. We are terminating a lot of cloud infrastructure on those, and it is able to handle traffic quite well; the only issue I might have seen is sometimes the IOPS drops, but that is again a firmware issue we had. Other than that, we have not seen any specific issues related to the cloud.

One of the reasons we chose Dell PowerScale was its capacity; if I remember correctly, the row capacity for it is somewhere around one petabyte. That was one of our key points. It also stores NVMe, has in-transit and at-rest encryption, and can be clustered up to a couple of hundred devices. We currently have a few devices coupled up, not in physically clustered, but virtually clustered, and we are not having any issues. The physical efficiency is also there, so all of that you are basically getting in one rack unit, which is not a huge physical footprint for us.

I am an administrator on a star team managing everything; we are the ones responsible for it. From physical management to software management, the underlying OS management, everything falls on us.

One of the performance metrics we use to measure success with Dell PowerScale is IOPS. Network connectivity is again important, and we also measure on our observability platform what kind of power consumption it is doing, what the expected power consumption is, and how well it is communicating with our other virtual clusters. These are the basic benchmarks at the moment, but I think that will change in the near future.

From a security point of view, we are using hardware security at the moment; we have TPM and Intel Secure Boot enabled, and our NVMe drives are encrypted. That is all we are doing for security at the moment.

We have not used Dell PowerScale much yet, so I cannot give feedback until we push it to the edge and see what goes haywire. The OS seems quite stable, and the integration goes quite well; we are not using it for intensive workloads at the moment, so it is hard for me to say what results it will bear under pressure.

I would recommend Dell PowerScale. However, it depends on what every customer is looking for and what kind of usage they have from use case to use case. If it is similar to ours, then that is the recommendation.

I have been working in my current field for almost seven and a half years now. Overall, I would rate Dell PowerScale as a 7.5 or 8 on a scale of one to ten.

Which deployment model are you using for this solution?

Migration has boosted all-flash performance and now supports faster engineering workloads
Pros and Cons
  • "The fact that the business saw a noticeable improvement in performance the day we switched over was a game-changer, not to mention the ability to seamlessly swap out the nodes to move from the older Isilon platform to Dell PowerScale, with no data migration, making everything seamless, done behind the scenes, and users only noticing the jump in performance."

    What is our primary use case?

    My role in using or managing Dell PowerScale is that I'm a director, so I manage a team of systems engineers and architects that administer and support these platforms.

    I have been using Dell PowerScale since we migrated from the Isilon platform this year, and during that initial migration, we noticed a noticeable increase in performance from switching over to PowerScale.

    What is most valuable?

    Dell PowerScale aligns with my organization's strategic goals of improving operational efficiency through platform modernization, since having Isilon before that was not all-flash. Moving to Dell PowerScale all-flash results in a noticeable jump in performance, with outreach from people on the engineering side noticing the speed in which they could open CAD/CAM workloads on Dell PowerScale, much faster than Isilon. The fact that the business saw a noticeable improvement in performance the day we switched over was a game-changer, not to mention the ability to seamlessly swap out the nodes to move from the older Isilon platform to Dell PowerScale, with no data migration, making everything seamless, done behind the scenes, and users only noticing the jump in performance.

    What needs improvement?

    We are extremely happy with the performance and the features that we have been given regarding Dell PowerScale, so I could not think of anything else right now, other than making it cheaper.

    The pricing, licensing, and setup costs are interesting for us as we utilize Dell Flex on Demand, paying for it with a consumption-based OpEx model. There is an initial upfront commitment, and as we grow, that ability to scale out as our growth scales, while not paying anything more than what we are using, holds great value for us.

    The comment about pricing improvement was more of humor, as we bought it on capital. With the consumption model, we pay a certain price per gigabyte, and as we grow and scale, that price gets lower the more we grow, so seeing that drop a bit more to be more competitive might help, but from a market perspective, Dell PowerScale was the leader from a cost standpoint when we did the pricing.

    For how long have I used the solution?

    I have been using Dell PowerScale since we migrated from the Isilon platform this year, and during that initial migration, we noticed a noticeable increase in performance from switching over to PowerScale.

    What do I think about the stability of the solution?

    The stability and reliability of Dell PowerScale have been rock-solid for us. Even with Isilon, I do not think we ever had something as much as a failed drive or a bad cable, so I am expecting that same kind of consistency and performance level with Dell PowerScale.

    There has been no downtime whatsoever, not even during the migration.

    What do I think about the scalability of the solution?

    Dell PowerScale absolutely grows with the needs of my organization.

    The Flex on Demand growth model allows us to scale up and scale out as we need to for data migrations. That seamless back-end process with no disruption was huge for us, unlike when we migrated from our older platform to Isilon the first time, which required a third-party software tool for data migration that was noisy and disruptive. This time, it was all done seamlessly just by swapping out the hardware.

    How are customer service and support?

    Since I have not used customer service and technical support, I do not need to rate them. Dell PowerScale has been rock-solid for us from a performance perspective. We have not had to need support, which is a good thing, but we know if we ever do need them, we have a TAM on our account and, from support engagement we have done for other products in the past, there are no concerns from that perspective.

    Which solution did I use previously and why did I switch?

    Before Isilon, we had a traditional Windows file system that ran on top of the Unity storage platform.

    We switched because Unity was a hybrid flash array, whereas Dell PowerScale is now all-flash, so from a performance and a modernization perspective, it made sense for us to do so.

    What was our ROI?

    I think we have seen return on investment with Dell PowerScale, just in the speed in which we can access the files and the engineering capabilities. We are also seeing where engineering uses it as a landing zone to run workloads, which in the past we never really allowed them to explore doing.

    We have identified other opportunities just outside of that traditional file share workload where we are permitting engineering to use it as a landing zone to run VMware workloads.

    What other advice do I have?

    Data governance is certainly a big emerging challenge for us as managing enterprise data. It is not just going to be dependent on our strategy for file shares but also involves our landscape with SharePoint sites and so forth. I think it is really more of a purpose-built solution, giving us that visibility in that space that we have never had before.

    Dell PowerScale does not currently play a role in my organization's AI initiatives, as we are a very big Microsoft shop doing a lot in the Copilot space. However, being an aerospace and defense company, we have limitations on what we can use from a cloud perspective. I think the tagging part will help because as we better understand where our data is and what access we are going to allow these AI tools to have, it will pay dividends in the future.

    I would rate Dell PowerScale a 10 overall.

    Which deployment model are you using for this solution?

    On-premises

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Implementation enables seamless archiving and data security
    Pros and Cons
    • "Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
    • "Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

    What is our primary use case?

    Before this project happened, I sat with the customer and understood what they needed for Dell PowerScale (Isilon). They have a surveillance system, and since it's unstructured, this was the first thing we recommended to use. 

    Since they needed to use this for archiving and had a long retention period, they wanted very good storage and high-capacity storage. That's why we recommended the A3000. 

    I worked with them on the sizing part and getting customer requirements. For step one, I came with the team here, who have people who are purely technical that will do the implementation. 

    I usually sit with them and the customer, understand, and check the flow of everything from A to Z. This is mainly my responsibility. From hands-on experience, since I spent my time mostly with technical engineers, I can do the same work as them if needed.

    What is most valuable?

    Any storage system has something called RAID, while Dell PowerScale (Isilon) uses the Reed-Solomon protocol. It's the same concept as RAID, however, it secures in case something happens on the node or the disks. In the Dell PowerScale (Isilon) system, this is calculated automatically. Instead of us assigning a RAID 5 or RAID 6, Dell automatically assigns, for example, for this project, they assigned something called 2d:1n, which means that in case of a failure of one node or two disks, the system will stay up and running. These are the protection features that I appreciate.

    From the deduplication part as well, there are many features. I was recently in a meeting with some people from Dell here in Saudi, and they were talking about the new Dell PowerScale (Isilon) systems that are AI-enabled. I didn't do much research on them, however I can see where Dell's direction is going with these features. 

    From the automation part or from making life easier for humans, I appreciate the approach they're taking. Based on the feedback I received from Dell people who worked on the new Dell PowerScale (Isilon) system, they said things are becoming more automated and they are able to help the technical people or the pre-sales people deploy the system even better. They even enable the customer to get more insights about their data.

    If something fails or there's a hardware issue, they can order parts online with Dell PowerScale (Isilon). The customer when ordering the system can add ProSupport, depending on the time needed and how critical their use case is for the system. If the customer pays for ProSupport, maintenance is very good, with service within four hours or the next business day, depending on what they order.

    Dell PowerScale (Isilon) is a NAS (Network Attached Storage) and supports scale out. You can add as many nodes and scale linearly. For the first purchase to create a cluster, you must buy four nodes. Moving forward, they can buy a pair of nodes at a time. It's very easy to scale out - just initialize the node and join it to the existing cluster.

    What needs improvement?

    With every iteration of the OneFS system, new features are being added, and the UI is being updated here and there. So far, the system is adequate as a whole. Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us. I remember seeing it somewhere. I don't recall if it's on the Dell system or not.

    For how long have I used the solution?

    I have been in this industry for around a year and a half. In terms of using Dell PowerScale (Isilon), I can say I've used it approximately one year.

    What do I think about the stability of the solution?

    I don't recall any time we did an installation or deployment of Dell PowerScale (Isilon) where a customer contacted us telling us the system wasn't working. Everything has been working properly.

    We mainly get hardware issues, such as hard disk failures. We occasionally see PSU defaults, not chassis failures. Since we have good protection levels, the data is secured and replicated across the disks.

    What do I think about the scalability of the solution?

    Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability.

    How are customer service and support?

    The level of service depends on the type of support with Dell PowerScale (Isilon). If discussing support through partners, I would give it an eight out of ten, however, support online is definitely a ten out of ten. When Dell people are involved directly, it's very good. That said, sometimes when they assign the task to a partner to deliver, it depends on the partner they are delivering the task to and the personnel they're sending.

    How would you rate customer service and support?

    How was the initial setup?

    We started yesterday with Dell PowerScale (Isilon) and we're almost done today. It's a small deployment with just one chassis that has four nodes, so it was quite easy. The more hardware you have, the more time you need. Initializing the cluster took us about four hours.

    We are a small team with Dell PowerScale (Isilon), around five or six people, depending on the project.

    What's my experience with pricing, setup cost, and licensing?

    It's considered between mid and high-end regarding. Dell usually knows how to position each model. If the customer wants something inexpensive, there's PowerVault. The system is marketed for mid-range to high-end pricing.

    What other advice do I have?

    I rate Dell PowerScale (Isilon) ten out of ten overall.

    Achieved significant data management efficiency with strong performance metrics and customer service
    Pros and Cons
    • "My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry."
    • "They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing."

    What is our primary use case?

    We are using many Dell products. Mainly for archiving and logs management, a huge amount of data is generated, so we are using Dell PowerScale (Isilon) in our environment.

    What is most valuable?

    The main structures of Dell PowerScale (Isilon) are pretty easy to manage, which I find most valuable. 

    In terms of performance metrics to measure success with Dell PowerScale (Isilon), we are measuring turnaround time, and the ROI is good. We are all satisfied because we haven't faced many issues with Dell PowerStore or VMAX.

    What needs improvement?

    There will always be room for improvement with Dell PowerScale (Isilon). They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing. 

    I'm not sure Dell PowerStore has non-disruptive upgrade capabilities; they can leverage these to boost performance without disrupting the environment. 

    Also, software updates can be done in a non-disruptive way, improving the performance.

    For how long have I used the solution?

    I have been working with Dell for more than 10 to 12 years.

    How are customer service and support?

    My experience with Dell as a vendor is pretty good; they are probably one of the best in the industry.

    How would you rate customer service and support?

    Positive

    Which solution did I use previously and why did I switch?

    This is my first time using Dell PowerStore, but I had worked with many NetApp products such as the NetApp A-series and AFF, and we are using Hitachi Vantara as well.

    What was our ROI?

    I have seen ROI with Dell PowerScale (Isilon). It would be after two or three months, because we need to leverage the dedupe and compression to measure the ROI effectively, considering how much data reduction happens, then we can calculate the CapEx and OpEx value.

    What other advice do I have?

    I'm working mainly with storage and backup, specifically using the Veritas backup solution and have hands-on experience. We are continuing using Dell in storage. Its features specifically cater to the needs of big organizations. I am a customer of Dell. On a scale of 1-10, I rate this solution a 9.

    Which deployment model are you using for this solution?

    Reliable imaging storage has supported faster diagnoses and improved patient care
    Pros and Cons
    • "I assess the stability and reliability of Dell PowerScale as top-notch, as the only issues we have ever had are just failed drives, which is to be expected."
    • "An example of something that is problematic at the moment or that I would want to see improved is that there needs to be further delineation between access zones and settings."

    What is our primary use case?

    Dell PowerScale serves as our primary storage for our PACS imaging, storing all of the radiology images across our entire business. Because of this critical function, it is extremely important that it remains up and running at all times.

    What is most valuable?

    The features of Dell PowerScale that I appreciate most include the ease of redundancy over networks, as we have one cluster in one location and another cluster in a disparate location. If one fails over, it is fairly easy to fail over to the secondary cluster.

    Dell PowerScale aligns with our organization's strategic goals of improving operational efficiency because it has always been targeted at unstructured data, which we use for our PACS imaging. It has always been well-aligned for what we needed, and we have been using it for quite some time, finding it very effective for our imaging.

    Dell PowerScale aligns with our organization's goals of supporting digital transformation initiatives, as we started with PowerScale nodes that only had spinning drives and have since moved to SSDs. Those SSDs have been faster, which improved our performance with our PACS systems.

    What needs improvement?

    Dell PowerScale is a very solid product right now, and I do not see any immediate improvements that it needs, but possibly some UI tweaking here and there and unification of settings would be beneficial. However, it still performs very well. I think it does need some easier user-facing management.

    An example of something that is problematic at the moment or that I would want to see improved is that there needs to be further delineation between access zones and settings. Things are not always clear as to what I am managing or what section of Dell PowerScale that I am actually managing. Additionally, the networking portion can be a little confusing in terms of access zones and what features I am actually editing or modifying. On top of that, the isi commands can get confusing at times; some only work on individual nodes while some are cluster-wide. There needs to be a little more clarification and more end-user ease of doing certain configuration tasks.

    What do I think about the stability of the solution?

    I assess the stability and reliability of Dell PowerScale as top-notch, as the only issues we have ever had are just failed drives, which is to be expected. We receive new drives proactively, and they are sent to us and are very easy to replace. Drive failure has been less prominent now that everything is solid-state, and it really is very reliable. We have never had a node motherboard fail or anything bigger than a drive, so it has all been very smooth.

    What do I think about the scalability of the solution?

    Dell PowerScale scales with the growing needs of our organization very simply, as all you do is attach nodes to your network, usually your top-of-rack switch, and you join it from the command line. It is a very simple process with only a few steps, and after that, I can get granular in my configuration for the nodes I have deployed. Initially deploying is very simple. Dell support is always there if I have questions after deployment.

    How are customer service and support?

    I evaluate the customer service and technical support for Dell PowerScale as very good, since it was actually the first enterprise application support that I have dealt with, and I have never had any problems. They have always gotten back to me within a couple of hours usually, and if there are higher priority cases, we have gone to our account supervisors, and they have been great. The general support is excellent; I never really had any problems with it. We use them for upgrades and general support, and both have been great. I would rate Dell PowerScale customer support a nine on a scale of one to ten, with one being worst and ten being best, as I have never had that many problems with support.

    Which solution did I use previously and why did I switch?

    Prior to adopting Dell PowerScale, we were using another solution to address similar needs, but I am not sure what the solution was. What we were using previously was slower. I think we have been using Dell PowerScale for approximately twenty years now, when it was previously Isilon. When we did adopt Isilon/PowerScale, we saw a major improvement.

    How was the initial setup?

    Regarding how easy or difficult it is to deploy Dell PowerScale and how long it takes to deploy, I am Isilon certified, which was previously PowerScale certified. I have done several virtual deployments and also physical, real deployments within our organization, and it is very easy to do. There are a couple of join commands that you do once the nodes are networked up, and it literally just adds the nodes to your cluster. There is no hassle; you configure them a little bit afterwards, but really, it just pushes those new nodes right into your cluster. The process is very simple.

    What was our ROI?

    I have seen return on investment with Dell PowerScale, as any amount of time that can be saved for our radiologists is ROI for us. The fact that Dell PowerScale is fast enough to support their needs means that we do not hear complaints, and second of all, images get read faster and patients get better quality of care.

    What's my experience with pricing, setup cost, and licensing?

    My experience with the pricing, setup cost, and licensing is minimal. I have set up a few nodes in my time, but it has always been very easy. I do not have the actual pricing or anything, as I have not deployed nodes and been involved in the pricing structure.

    What other advice do I have?

    Dell PowerScale does not play a role in our organization's AI initiatives right now.

    My advice to organizations considering Dell PowerScale is that if you are an organization that uses unstructured data, it is a beautiful way to go. Definitely consider it as one of your top choices. I would rate this review a nine on a scale of one to ten.

    Storage has supported virtualization workloads but requires better support and modern features
    Pros and Cons
    • "The maintenance is very good, and the deployment is straightforward as well."
    • "Beyond containerized storage support and software updating, I have had very bad experiences with Dell PowerScale (Isilon) because they present more issues than other storage options, even when compared with NetApp."

    What is our primary use case?

    Our primary use cases include virtualization storage and external storage via NFS.

    What is most valuable?

    I find that the features of Dell PowerScale (Isilon) are not extensive. Our customer chooses Dell PowerScale (Isilon) because of the pricing issue, not the functionality. They discovered that the reseller in Taiwan has a per gigabyte price that is more expensive than Dell PowerScale (Isilon). The maintenance is good, but the subscription fee is higher than other storage solutions.

    The maintenance is very good, and the deployment is straightforward as well. Pure Storage is still our first choice if we want a very fast deployment or engagement.

    In our customer's company that is a campus, around 5,000 people use Dell PowerScale (Isilon). Among corporate enterprise customers, they do not use larger options like the big FlashArray; they are only using smaller solutions like FlashStack, which may accommodate around 100 to 200 employees in each enterprise customer.

    What needs improvement?

    I think Dell PowerScale (Isilon) could improve some functions such as Apache S3 or containerized storage support, as these aspects are not well-developed. Their support system is weak; many issues require us to conduct our own research and apply solutions to the equipment, so using Dell PowerScale (Isilon) demands more maintenance effort from us.

    Not much noticeable improvement or impact from Dell PowerScale (Isilon) is observed in our customer's business operations. We still discuss with our customer that Dell PowerScale (Isilon) is not the best or most suitable choice. Our customer is always focused on three things: they want to minimize maintenance effort, they question pricing if functionality is not different, and they consider our professional services. Dell PowerScale (Isilon) requires us to spend more man-hours on maintenance compared to Pure Storage.

    In terms of what Dell PowerScale (Isilon) could learn from Pure, I would say they lack certain features such as upscaling; they do not have an Evergreen program as Pure has, and their support system is weak. Firmware or software updates become effortless with Pure, but with Dell PowerScale (Isilon), we must evaluate or conduct trial runs to ensure that these operations will not harm our customer's system; their software is not adequate.

    What do I think about the scalability of the solution?

    Currently, the AI capabilities of Dell PowerScale (Isilon) pertain more to lake services. However, our customer does not have this big data storage; their dataset is average, around 100 gigabits or 100 gigabytes. With 100 gigabytes, the performance will be comparable between Dell PowerScale (Isilon) and Pure, especially within FlashArray, as the dataset is not enough to push the machine's limits.

    What other advice do I have?

    We always use random write and read metrics with 4K files, and possibly also 1K files. This is a script we have coded via some cloud solutions. Currently, our customer does not face throughput issues because the network infrastructure does not keep pace; the bottleneck is consistently the latency of the switch.

    Beyond containerized storage support and software updating, I have had very bad experiences with Dell PowerScale (Isilon) because they present more issues than other storage options, even when compared with NetApp. They lack sufficient support, and their software is not user-friendly. If I were to suggest any improvements, it would be to enhance their software. I would rate this review overall as a seven out of ten.

    Manages large data sets efficiently with hybrid cloud integration
    Pros and Cons
    • "Customer service has been really good."
    • "The most valuable feature for me is SyncIQ."
    • "The solution is expensive. It's quite expensive for the amount of storage we have."

    What is our primary use case?

    Our healthcare storage needs require us to store off several radiology images and use the data since November 2018.

    How has it helped my organization?

    The product has helped my organization by managing large data sets.

    What is most valuable?

    The most valuable feature for me is SyncIQ. The reason I find it valuable is its data resilience. 

    What needs improvement?

    There's nothing really I'd improve about the product. We're currently expanding it, so we're going to our next generation of Dell PowerScale (Isilon) since we've had it since 2018. We're consolidating as drive sizes have gone bigger, and we're consolidating the footprint down. That's what we're currently doing.

    For how long have I used the solution?

    We have had the solution since 2018.

    What do I think about the stability of the solution?

    I find the product to be resilient and stable. There's no downtime and no crashes; over the years, we have experienced some issues, yet nothing major. The key components are the helper cloud pools and S3 IAQ.

    What do I think about the scalability of the solution?

    My organization is quite large, with about 30,000 employees.

    The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.

    How are customer service and support?

    Customer service has been really good. 

    How would you rate customer service and support?

    Positive

    Which solution did I use previously and why did I switch?

    Before Dell PowerScale (Isilon), we were using standard Windows SMB back in 2018. The data had grown so much within six, seven years. It was just standard Windows SMB.

    How was the initial setup?

    I have not compared it to other products in terms of deployment. I have been part of the deployment of the product. It's very straightforward. there were no issues in implementing it.

    What's my experience with pricing, setup cost, and licensing?

    The solution is expensive. It's quite expensive for the amount of storage we have.

    What other advice do I have?

    On a scale of one to ten, I rate the product overall about eight.

    Which deployment model are you using for this solution?

    Hybrid Cloud

    Unified storage has simplified managing petabytes of unstructured data across diverse workloads
    Pros and Cons
    • "Dell PowerScale is much more advanced compared to competitors, offering more flexibility with different types of drives and nodes, and in terms of simplicity in management."
    • "The existing integration is there, but the only negative point I see about Dell PowerScale is mainly the pricing perspective because it is not intended for SMBs, but for enterprise customers."

    What is our primary use case?

    Dell PowerScale is suitable for NAS, CCTV, and unstructured data, primarily as a scale-out NAS system designed to manage petabytes of data in a single namespace.
    In handling enterprise data, data is crucial, akin to the new oil. Unstructured data is continuously generated, requiring a suitable platform for management that offers scalability, data protection, privacy, and multi-tenancy. Dell PowerScale provides these features, enabling enterprise customers to use a unified platform for collecting data from various sources. This platform can serve as a home directory, support CCTV, and accommodate different use cases like Hadoop object-based storage, all managed through one dashboard, cluster, and with a unified management perspective.

    What is most valuable?

    The main advantages of Dell PowerScale are its scalability and ease of scaling, as it can handle petabytes of data in a single namespace, and its simplicity to manage. Unlike other products, which may require multiple file servers, Dell PowerScale allows petabytes of data in a single namespace, managed by just one person. This is particularly beneficial for large-scale data, such as airport CCTV recordings, which can reach many petabytes.
    Performance is another key feature, with various tiers based on data requirements, including NVMe, flash nodes, hybrid, and nodes for deep archive. Dell PowerScale also offers strong data protection, allowing for the loss of at least one drive or node without disrupting operations.
    Operational efficiency and ease of use with Dell PowerScale are notable, as managing the entire cluster is straightforward compared to other NAS infrastructures. The single namespace simplifies user experience.
    Dell PowerScale supports multiple protocols, enabling it to function as a data lake. It can host various data types on the same platform, with data accessible via CIFS, NFS, or S3. It supports CIFS, NFS, SMB, S3 for object-based data, Hadoop, HDFS, parallel file systems, and ITBR superpod for Nvidia GPUs, which are part of AI storage.
    Dell PowerScale integrates with AIOps for analytics, supporting AI workloads by connecting directly to GPUs for high performance.

    What needs improvement?

    One of the areas for improvement could be a more proper direct integration with Dell PowerProtect Data Manager and PowerProtect Data Domain. This would enhance cyber resiliency features such as anomaly detection. Having a backup solution similar to what is available with PowerStore and Data Domain for enterprise customers would be beneficial.

    The existing integration is there, but the only negative point I see about Dell PowerScale is mainly the pricing perspective because it is not intended for SMBs, but for enterprise customers. Dell PowerScale cannot be compared with Synology solutions. It is an enterprise solution, which means its pricing and features are geared towards enterprise usage. A starter kit for small and medium businesses would be good.

    For how long have I used the solution?

    I have been working with Dell PowerScale, formerly known as Isilon, for eight years.

    What do I think about the stability of the solution?

    Dell PowerScale is very stable and scalable because it has a very nice data protection strategy, and it can scale petabytes on a single namespace.

    How are customer service and support?

    The technical support from Dell is good regarding Dell PowerScale, although I believe it could sometimes be better. I would rate the support at nine out of ten.

    What was our ROI?

    In terms of price, it is quite pricey, but regarding return on investment, customers can observe ROI with Dell PowerScale because it can be used for multiple use cases. If customers have this platform in their data center, they will find that a lot of data can be consolidated under a single platform, making it better than having different devices for backups or small NAS solutions.

    What other advice do I have?

    I am working with Dell PowerScale today, which is also called Isilon.

    Dell PowerScale is much more advanced compared to competitors, offering more flexibility with different types of drives and nodes, and in terms of simplicity in management.

    The deployment procedure for Dell PowerScale is quite straightforward. If you are certified for deployment, you can manage it easily.

    I do not have performance metrics or benchmarks to measure success with Dell PowerScale.

    My review rating for Dell PowerScale is nine out of ten.

    Which deployment model are you using for this solution?

    Hybrid Cloud

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Capacity and scalability have been excellent for managing our data needs
    Pros and Cons
    • "The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."
    • "The technical support has been excellent. I would give them a ten out of ten for support."
    • "We're still fairly new with it. It's been a pretty positive experience thus far. However, they could improve implementation, as we had to rack and stack it ourselves."

    What is our primary use case?

    Our use cases involve sheer storage, as it's about 4 petabytes of storage that we use for our genetics team for storing big data.

    What is most valuable?

    The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it.

    What needs improvement?

    We're still fairly new with it. It's been a pretty positive experience thus far. However, they could improve implementation, as we had to rack and stack it ourselves.

    For how long have I used the solution?

    We have been using the product for less than three months, as we just got it.

    What do I think about the stability of the solution?

    The stability has been excellent thus far, with no issues.

    What do I think about the scalability of the solution?

    The scalability is excellent.

    Dell PowerScale (Isilon) has features that cater to the needs of medium-sized organizations. It's a pretty configurable product. We're running with about 4 petabytes, which is a massive amount of data, but I know you can run it with much less. 

    I see Dell products growing with our future needs. Our company has about 400 people working. 

    How are customer service and support?

    The technical support has been excellent. I would give them a ten out of ten for support.

    How would you rate customer service and support?

    Positive

    Which solution did I use previously and why did I switch?

    We were using NetApp previously. We haven't used Dell PowerScale (Isilon) long enough to give a full comparison at this point, but they both seem to be pretty comparable products.

    How was the initial setup?

    The initial deployment was fairly easy. It took two of our guys, but it would have been nice to have a white glove service so they would rack it, and we could have just configured it. Overall, it took less than a day.

    It requires very little maintenance on our end.

    What about the implementation team?

    Two people were required for this type of job overall.

    What's my experience with pricing, setup cost, and licensing?

    The pricing is excellent.

    What other advice do I have?

    Dell PowerScale (Isilon) does not play a role in our organization's AI initiatives at this time. 

    I would rate Dell PowerScale (Isilon) a nine out of ten.

    Which deployment model are you using for this solution?

    On-premises

    Reliable storage has improved daily operations and has simplified data management tasks
    Pros and Cons
    • "Dell PowerScale is very stable and scalable; when you are working at one hundred percent capacity without issues, I trust the product, the software, and the infrastructure here."
    • "Sometimes my team needs to restart the machine or restart VMware, which takes a long time."

    What is our primary use case?

    Dell PowerScale is my responsibility for handling the general information we have.

    What is most valuable?

    The biggest advantage of Dell PowerScale is stability. It is easy to manage because Dell and HP are famous products worldwide and here in Egypt. Regarding operational efficiency, Dell PowerScale is good and easy to use. When you have good support, you have a good experience, and it is easy to work with. You receive good support from the supplier or the company.

    What needs improvement?

    Sometimes my team needs to restart the machine or restart VMware, which takes a long time. Not every time can we do this. I mentioned before that the stability is good from Dell and HP.

    For how long have I used the solution?

    We have been using Dell PowerScale for one year and a half.

    What do I think about the stability of the solution?

    Dell PowerScale is very stable and scalable. When you are working at one hundred percent capacity without issues, I trust the product, the software, and the infrastructure here.

    How are customer service and support?

    Regarding technical support from Dell, it is very good. If I were to rate support on a scale from zero to ten points, where ten is the maximum, I would give it ninety to ninety-five percent.

    How was the initial setup?

    The installation of Dell PowerScale is very easy.

    What was our ROI?

    Dell PowerScale saves us some time and money. We chose Dell for this because we have been using Dell for about twenty-five to thirty years.

    What other advice do I have?

    I am currently using HCI products, specifically Nutanix and VMware. We use subscription-based HCI products and hardware solutions. We use hardware such as Dell machines, FortiGate firewall, and Juniper switches. Our servers are mostly Dell machines. We also use Kaspersky antivirus software and several other solutions. The router is from Egypt Telecom. We work with Dell PowerScale. I am not certain if our savings are ten percent, twenty percent, or more. Data management strategy is crucial, particularly regarding how multi-protocol support impacts our data management approach. We are partners with Amazon and AWS. We use Microsoft 365 and Microsoft Azure. We have already established some success measures with Dell PowerScale, but I cannot provide the detailed results. Dell manages adaptation to new challenges very well, and we do not have any problems with support from Dell. Everything is very stable and functioning properly. The network team and I have met, and everything is working fine. I am not missing anything currently, and everything supported by Dell is good and easy to work with. We work in the healthcare sector, and AI is not something we can trust one hundred percent for patients, making it very difficult to use in the healthcare section at this time. The most beneficial security features include Forti and Kaspersky, and we previously used Sophos firewall and antivirus. Dell PowerScale is very stable and easy to use. Sometimes we have to restart the machine, but it is not heavy work, and it is easy to do when needed. My overall rating for this review is nine out of ten.
