Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Unified storage solution supports cross-vendor replication and diverse industries
One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

Managing mixed RAID workloads has improved data protection and delivers strong performance
VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."
"This solution has helped my organization by cutting down on provisioning time; I used to have to provision a VM and it would take ten minutes, now, it takes thirty seconds."
"The sales and executive support have been outstanding compared to the rest of the market... My upgrade paths have been simple on the Pure... It's a lot simpler to implement and a lot simpler to manage."
"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."
"I would definitely suggest this solution to a colleague because of the ease of use."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"At this point, I don't know anything that they could provide in a better way."
"Being able to move things around from one array to the other has been the biggest feature for us."
"It's the best mainframe storage available."
"I would recommend IBM Spectrum Virtualize because it is very robust, stable, and affordable, has very good performance, and is relatively easy to implement and use."
"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."
"So when I say our storage services to our client were provided continuously - non-stop - for 12 months, it means that all customer servers had 100% uninterrupted, online SAN access to their data 24x7x365 (minus the power down)."
"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."
"We can scale it very easily for a test environment. We were able to segment our DMZ so it wasn't connected to anything, which we really liked."
"The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
"The stability of the product is very good."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"The most valuable feature is the simplicity of its scalability: being able to grow it without having to make sure you get the right disks and the right nodes. The solution is also easy to manage. It's all right there in the vSphere Client. You're not going through multiple things. You don't have to know, once you've created the vSAN node. You add storage, it sees it, and you create your data storage from there. Everything is right there for you."
"I like the tolerance of VMware vSAN."
"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."
"vSAN is a very cost-effective solution for just about any data center, as it is very easy to deploy, scale and manage while being built on commodity hardware so customers do not have to break the bank to invest in this technology compared to a much more costly centralized storage array."
 

Cons

"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"Most of our upgrades have not been as smooth as they should have been."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform."
"One very important feature is the analysis of the logs which should be there in the system."
"Maybe sometimes we don't get responses back as fast as we would like, but they have always been very professional and they follow through."
"Cheaper pricing and GUI should be developed in HTML5 as opposed to Java."
"One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"The product should have better management capabilities."
"The management platforms have some gaps. It's difficult to see what's going on with the hardware at times."
"I would like to see faster re-sync and recovery times after a host failure. It’s so difficult to restore a normal situation after a failure."
"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array."
"There is a lot that VMware could improve from a marketing perspective. The cloud is still new for many people, so extending storage should be effortless. It shouldn't be so complicated to extend the storage so workloads can access it no matter where they go."
"It would be ideal if the solution offered some intelligent monitoring."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity."
"If the support could be provided more quickly, it would be very helpful."
"The management of vSAN (dashboard, alerts, monitoring) has a significant amount of growth potential."
 

Pricing and Cost Advice

"Our Evergreen Storage subscription is supposed to be good when we go to upgrade."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"The licensing is $100,000."
"Cost-wise, it's been very effective."
"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."
"The solution is expensive."
"Pricing is moderate. It is neither cheap nor expensive."
"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"We would like the CPU cycle to save more on the licensing costs for us."
"This solution came as an additional cost for the TSM package we chose."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"It has a lot of advanced functions for a reasonable price."
"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."
"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."
"I'd love for this product to be cheaper."
"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
"The licensing cost is high and should be taken into account."
"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."
"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."
"This solution is expensive. Nutanix provides us with Acropolis Operating System (AOS) along with its hardware, while VMware provides vSAN, vCenter, and vSphere which all have separate licenses and costs."
"The price is expensive."
"It could be cheaper."
