We use it for SAN and NAS, pretty much all of our VMware and ERP systems; everything for storage. It' working out very well. We just moved into it
IT Manager at a energy/utilities company with 10,001+ employees
Consistency Groups and integration of SAN and NAS make replication simple for us
Pros and Cons
- "They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working not just for replication but for backups as well."
What is our primary use case?
What is most valuable?
They've integrated NAS and SAN pretty well. It made replication very simple. Because one of our systems has a lot of LANs, for it to replicate we have Consistency Groups in there. That's something that is really helpful, making sure that everything is working, not just for replication but for backups as well. Pretty much everything we need is there.
What needs improvement?
We're probably going to be looking into vSAN just to minimize the footprint. We've already minimized the footprint going from VNX to the Unity, but as we're virtualizing more and more, once we're completely virtualized, we'd probably be looking into vSAN through either VxRail or VxRack, and go that way. The smaller the footprint at the data center, the less cost there is.
For how long have I used the solution?
Less than one year.

851,823 professionals have used our research since 2012.
What do I think about the stability of the solution?
So far, we've had no issues. We've been running the Unity for about half a year now; no issues with stability at all.
What do I think about the scalability of the solution?
We've only had it for a short time so we haven't had to scale up. We got it scaled to our needs with a little bit of growth put on there.
How are customer service and support?
The team that we got to help us implement it were spot on. They really did do a great job. There were a few cases where we had to pull in some more experienced guys for the networking aspect of it, for the NAS, as there were some issues. But everything else was spot on.
How was the initial setup?
The initial setup was fairly simple because they were able to take all of our information from the VNX and size it appropriately, have all the LUNs set up. The only complex part about it was how we were going to do the SAN to SAN replication, which involved getting everybody on all of the equipment on the latest code, to make sure that we could actually go ahead and replicate. That took some extra work to get that done, but in the end, it was all taken care of and we got replication going.
What's my experience with pricing, setup cost, and licensing?
The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense.
I can't say enough about the Flex on Demand because it gives you the agility you need. You can get it in there so easily. You don't have to be fighting with the CFO about how much it costs. It's a lot easier.
What other advice do I have?
It's a really good buy.
We're about to replace a VNX with a Unity in our DR facility. We love that it's only taking about half a rack of space versus the rack-and-a-half that we have for the VNX. That's really good. We're going to be doing SAN to SAN replication. We currently have that going on between the Unity and the VNX using RecoverPoint Appliances, but then it's going to be Unity to Unity after we're done.
I'm very happy with the Unity right now.

Senior IT Business Analyst at a pharma/biotech company with 1,001-5,000 employees
We look to update our datastores while operational, but we have had hardware issues
Pros and Cons
- "We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
- "Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
What is our primary use case?
We use it for ESXi data stores and performance seems to be okay so far. We've only had it a couple months. We have it integrated with VMware.
How has it helped my organization?
The benefits are the stability and that we're able to contact Dell EMC support for a quick turnaround. We have a higher level of support. If we have issues, they generally get fixed quickly.
What is most valuable?
Our hope is that they stay up, online, and that we will be able to update them while the data stores are operational. That is why we picked them.
Once it is set up, it is definitely easy to manage.
What needs improvement?
We've got an ongoing issue with a Unity in which some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR, which has been a struggle. It doesn't seem to affect performance but it's something that we're hoping the engineers can resolve.
We have also had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that.
For how long have I used the solution?
Less than one year.
What do I think about the stability of the solution?
The stability has been fine so far. We're good during normal operations.
What do I think about the scalability of the solution?
In terms of scalability, the size is fine for the environment we have. We're usually at about half the capacity, so we have quite a bit more we can expand with. It's good.
How is customer service and technical support?
In most situations, tech support works really well. If there are technical logs that they can diagnose and actually pull something out of, fantastic. If there aren't, if it's an abstract sort of issue, like the fan issues we're having, where they cycle every six minutes, it's taken me about six weeks.
They didn't believe me that the environment was not too hot. So they sent a technician out just to make sure that I could read the thermostat, that it was 68 degrees in our office. Then, they sent someone out to reseed each component, which I had already done. I didn't appreciate that part because I did some of those basics. I did exactly what they had said on the phone. The third time, they actually replaced some components and the fourth time they just sent the components to be replaced. It appeared to work, the fan issue did appear to go away, but it came back a couple of weeks later, after an update. I'm not sure if it's update-related, but it came back.
How was the initial setup?
Because I've done the setup before with the VNXe version, it was straightforward. It's very similar to the VNXe.
What's my experience with pricing, setup cost, and licensing?
Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out.
What other advice do I have?
Study the configurations of what you need to use and ensure you understand what you're provisioning. The procurement process can be a little daunting because there are a lot of features and there are a lot of components that you'll get set up with but which you may not need.
When selecting a vendor, what's important for me are global, 24-hour support; being able to get things fixed. After that, price, because we'll probably buy a thousand of them over time.

Infrastructure Manager at a hospitality company
It is scalable and supports small environments and larger deployments.
What is most valuable?
- Fiber channel connectivity
- Fast cache features
- Support of VVOLS
- 10GB NICs
- Support of high performance and rapid provisioning/expansion options
- Deployment time is quick from unboxing to setup
- Scalable
- Supports both small environments and larger deployments
- Supports hosts connected via fiber channel directly to the unit without the need for fabric switches
How has it helped my organization?
Unity 300 is now the go-to storage device we use as we virtualize our infrastructure.
The SAN currently exceeds our requirements in terms of performance. We have estimated for 30% growth per year for three years. The configuration purchased had storage capacity and performance to match these requirements.
EMC provided a slightly alternative solution using all-flash negating all disk I/O, latency, and contention issues. We have seen a huge performance increase due to all-flash that is beyond what was anticipated. In three years, when the storage is close to its limits capacity-wise, performance will be greater than necessary.
What needs improvement?
The SAN provided by EMC exceeded our expectations. The only room for improvement I can see would be a faster leader time and lower cost. However, even with the lead time we had (which was approximately 10 days at the time of order) and cost we are very satisfied with the product.
For how long have I used the solution?
I have used EMC Unity since June, 2016.
What do I think about the stability of the solution?
We have not had any stability problems.
What do I think about the scalability of the solution?
We have not had any scalability problems.
How are customer service and technical support?
Technical support is excellent. They have rapid response teams, ESRs, and the EMC account managers are always available.
Which solution did I use previously and why did I switch?
We had no previous SAN solution.
How was the initial setup?
The initial setup was very simple and instructions were provided in both documents and video tutorials.
What's my experience with pricing, setup cost, and licensing?
Licensing ranges from $20K plus for a decent configuration. AFA configurations start at about $25K.
Which other solutions did I evaluate?
We looked at multiple vendors including NetApp, HPE, IBM, and Nimble.
What other advice do I have?
There is currently a long lead time on 3TB SSD disks due to a shortage of materials in the USA.

Network manager at Farabi
Easy to use with a good response time and very reliable
Pros and Cons
- "It is easy to set up the solution."
- "We cannot connect directly with Dell due to sanctions."
What is our primary use case?
We primarily use the solution for storage for our online services.
What is most valuable?
The response time is good. It is suitable.
The product is easy to use. It's not complicated at all.
We do have some sanctions in our country, and this solution is one of the options we have available to us.
It is easy to set up the solution.
What needs improvement?
You need to self-study. We'd like, however, to get professional training. It would be ideal to have some online sources available to us to help us understand its capabilities.
We cannot connect directly with Dell due to sanctions. We'd like to be able to connect to the distributor directly as sometimes we sometimes get the wrong information. It would help with transparency.
For how long have I used the solution?
I've been dealing with the solution for about six months.
What do I think about the stability of the solution?
It has been really stable up to this point. There are no bugs or glitches. It does not crash or freeze.
What do I think about the scalability of the solution?
There are three of us using the solution. We have more than 3,000 customers using the product.
It's scalable. Everyone has been pretty happy with its capabilities.
How are customer service and support?
I've never dealt with technical support in the past.
How was the initial setup?
The product is not complicated to set up. The implementation is simple.
It is quick to deploy. It took us about three weeks.
We gathered the hardware, and we used the servers to connect to the host. It was pretty simple.
What about the implementation team?
We handled the deployment in-house with instructions or by looking at YouTube for direction.
What was our ROI?
We have not witnessed an ROI at this point. That said, we do see that it is worth the money.
What's my experience with pricing, setup cost, and licensing?
I'm not sure of the exact licensing cost of the solution.
What other advice do I have?
We are a broker. We're users. We are medium-sized, not enterprise-sized.
I'd recommend the solution to others. It is easy to use, scalable, and easy to set up.
I would rate the solution eight out of ten.
Which deployment model are you using for this solution?
On-premises

System Advisor at CRIF SpA
It is simple to maintain and has knowledgeable technical support, but it is expensive
Pros and Cons
- "The most valuable aspects of this solution are its stability, performance, and ease of updating."
- "There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
What is our primary use case?
I am an end user.
We use Dell Unity XT as a block and file system.
What is most valuable?
The most valuable aspects of this solution are its stability, performance, and ease of updating. Overall, it provides good performance and stability.
What needs improvement?
There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available.
The de-duplication function is back in the new Dell PowerStore, but it is missing in Dell Unity XT.
For how long have I used the solution?
I have been working with Dell Unity XT for four years.
I have started to use a new product from Dell called PowerStore.
I still use Unity, but I stopped using Bionic because it's unsupported and, as far as I can tell, it will be discontinued in January 2022.
It's nearing the end of support, which is why I purchased a new product known as PowerStore and am in the process of migrating to new storage at PowerStore.
I have time to check and test performance, as well as PowerStore, but I have extensive experience with Unity.
The version depends on whether it is a hardware or software version.
The hardware model is 400, and it is a hybrid store because the storage is shown as SAS and SSD disc.
What do I think about the stability of the solution?
Dell Unity XT is very stable.
I would rate the stability of Dell Unity XT a five out of five.
What do I think about the scalability of the solution?
Dell Unity XT is scalable. It is easy to scale.
Scalability, I've done it a few times with new enclosures, and it's a simple process to connect and extend. It's straightforward.
I would rate the scalability a five out of five.
The product is not specifically designed for users but I believe it is for a few thousand or more clients. It is for our production where production services and applications are deployed and exposed to our clients.
How are customer service and support?
Technical support is good.
In the four years that we have used this solution, it's been good, and I would rate technical support a five out of five.
It is simple to create a ticket, and they have good skills.
I have the highest level of support for our mission-critical operations.
It's very fast with good skills.
I am happy with the technical support.
Which solution did I use previously and why did I switch?
I used two storage units a year ago. The Unity storage is newer, whereas the Bionic storage is older. However, Dell now manufactures new storage as a Dell PowerStore.
I have two products, Dell Unity XT, and Dell PowerStore.
It has three storage units. It was Bionics first, and Unity is now in production. And we have been using PowerStore for two years. I am still interested in using Unity because the end of support for Unity is in 2025.
Bionics' support is about to expire in a few months. I purchased PowerStore. It's storage; everything after that is flash storage. And I migrate from Bionics to PowerStore, but I believe I will continue to use Unity for a few years.
Bionics was the first product we deployed before moving to Dell Unity XT., and then to Dell PowerStore.
How was the initial setup?
We moved from one location to another because the data center was our private cloud.
I am not familiar with the initial setup, because it was deployed when I went to this company.
I maintain this solution myself.
What's my experience with pricing, setup cost, and licensing?
The license is not required, but we must renew the support every year, every two years.
I believe it is overpriced. I don't have a lot of experience with other vendors, but I believe it is expensive.
I would rate the price a three out of five.
PowerStore support is more efficient now that I have experience with it. I won't go back based on the cost of support; PowerStore is the most straightforward.
What other advice do I have?
I would recommend this solution to others, but it depends on the need for de-duplication. If your data is encrypted or hidden, you don't need de-duplication. Dell Unity XT is good, but if the data isn't encrypted or is hidden, I recommend PowerStore. I would not recommend Unity where the data isn't encrypted and is hidden.
I would rate Dell Unity XT a seven out of ten because the de-duplication is missing.
Which deployment model are you using for this solution?
Private Cloud

Management Information System Officer at a mining and metals company with 501-1,000 employees
Beneficial data duplication, high availability, and proactive support
Pros and Cons
- "The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
- "Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
What is our primary use case?
Dell Unity XT is used for data storage at a data center.
How has it helped my organization?
Dell Unity XT has improved our organization's performance. We have seen reduced management times.
What is most valuable?
The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it.
What needs improvement?
Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works.
For how long have I used the solution?
I have been using Dell Unity XT for approximately two years.
What do I think about the stability of the solution?
Dell Unity XT is a very stable and reliable solution. We can leave the solution alone for a month without needing to check on how the unit is operating, or if there are problems. We realized the benefit of using the solution in approximately one year of use.
What do I think about the scalability of the solution?
The scalability of Dell Unity XT is good because during the period of one year we noticed we had the need to add more and more systems, and more components to it and we were able to do it with no hassle. We do not plan to increase our usage.
We have approximately 500 endpoints using this solution.
How are customer service and support?
The support from Dell Unity XT is good. They actively monitor the units. They have called us up when they have lost connection to one of the units to then take action. We have not had any issues to have needed to contact the support directly.
I rate the support of Dell Unity XT a nine out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I was previously using HP High-Performance Unit Storages. There was a need to purchase a new unit because we were struggling with the resources, performance, support, and other aspects. The best solution that was on offer that came to us was Dell Unity XT. The company decided to move to it and buy the full flash version to support all the applications that we have on-site.
How was the initial setup?
The initial setup of Dell Unity XT was straightforward because we had Dell representatives involved with our team.
We had to do a migration because we wanted to ensure that there was no downtime during the migration process from the old solution to the Dell Unity XT. To complete everything live without the business noticing that something is going on in the background.
You cannot have two groups of equipment that are deployed at the same time. For example, the host, storage, and switches. We had to ensure that everything is deployed, updated, and then do the connections between the two solutions and start with the migrations.
What about the implementation team?
We use Dell representatives for the implementation of the solution. We ended up doing the configurations ourselves without needing the support. 80 percent of the deployment we did ourselves. We had two people involved in the deployment and the solution has not required any maintenance so far.
We deployed not only the one Dell Unity XT but a bunch of them. It took us approximately one week for everything to be finished. Additionally, we deployed some hosts, switches, and other systems.
What was our ROI?
We have received a return on investment using Dell Unity XT.
We were able to solve the performance issues we were having. Our core communications and infrastructure is dependent on these units. The fact that all of the systems that we have improved significantly in terms of performance. The organization has benefited or is happy with the investment they've done at this point.
We have received a full return on investment from using the solution for three to four years.
What's my experience with pricing, setup cost, and licensing?
The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price.
If you want to scale or add additional components, this is where the price starts to spike or become very complicated and expensive. If you purchase the components separately they can cost a lot.
Which other solutions did I evaluate?
We did not evaluate other solutions before choosing Dell Unity XT.
What other advice do I have?
My advice to others would be for them to purchase the solution urgently if they need a backup solution.
I rate Dell Unity XT a ten out of ten.
Which deployment model are you using for this solution?
On-premises

IT Manager - Storage & Backup at a healthcare company with 10,001+ employees
Easy to use and provides storage with high IOPS and low latency
Pros and Cons
- "The All-Flash models are pretty fast for the vast majority of our remote workloads."
- "We would like to see the concept of Storage Groups brought back to this product line."
What is our primary use case?
We use this solution for remote sites with greater than 20TB & less than 100TB in block storage requirements. We utilize Dell EMC Unity 350f for ESX hosts and some CIFS & NFS NAS needs. We also use these arrays for DR needs to help control cost for primary block storage needs.
How has it helped my organization?
The Unity Arrays are easy to deploy and maintain. The All-Flash models are intuitive and easy to work with, in addition to providing high IOPS with low latency to support Business Critical applications. Because of the newer features and performance, it's easy to maintain and support remotely.
What is most valuable?
The All-Flash models are pretty fast for the vast majority of our remote workloads.
Encryption (data at rest - DAR) is easy to implement and has very little performance overhead.
CloudIQ SaaS is also a nice touch and is available for free. You can remotely monitor the health and performance of the arrays online or via a mobile app.
What needs improvement?
We would like to see the concept of Storage Groups brought back to this product line. Manually assigning new LUNs & removing LUNs at sites with a few ESX hosts in a cluster is fairly easy and straightforward, but when you have large clusters with twenty to thirty hosts, this becomes a burden. Because of this, we have limited the use of Unity systems in our larger data centers.
For how long have I used the solution?
Between two and three years.

Storage and Virtualization Engineer at a healthcare company with 1,001-5,000 employees
Gives us the ability to provision storage from the CLI, but needs native replication
Pros and Cons
- "The most valuable feature is the ability to provision storage from the CLI, versus having to go in and use the GUI every time. I can just script it out and it will create what I need. That makes it super-easy to manage. Also, for us, it's a set-and-forget. Once we provisioned it out, we haven't had to mess with it."
- "It could always use native replication. Then I could get rid of RecoverPoint."
What is our primary use case?
Primarily we use it for our file side storage. It's pretty solid. It's tied into our VMware environment for the virtual storage, but Exchange doesn't run on it. It's mostly just Windows File Servers at this point.
We had some issues with it in the beginning, but Dell EMC took care of them and it has just been sitting there running ever since. We haven't had any real problems since then.
How has it helped my organization?
For us, it is cheap and deep. That's really why we wanted it, to get an expanded amount of storage. We also run Xtremes, but they're a lot more expensive. Really, it was the cost-benefit for longterm storage.
What is most valuable?
The most valuable feature is the ability to provision storage from the CLI, versus having to go in and use the GUI every time. I can just script it out and it will create what I need. That makes it super-easy to manage.
Also, for us, it's a set-and-forget. Since we provisioned it out, we haven't had to mess with it.
What needs improvement?
It could always use native replication. Then I could get rid of RecoverPoint.
What do I think about the stability of the solution?
We had some problems in the beginning, but since they did the code upgrade and the bug fix, it has been solid for the last eight months. We haven't had any issues.
What do I think about the scalability of the solution?
Scaling is easy. If we need more, we just buy another shelf. It's probably not as easy as the Isilon, but it scales well.
How are customer service and technical support?
Our local SE guy is awesome. Everything we have is set to call home, so that's the set-and-forget for us. If there's an issue that pops up, they immediately send equipment to our SE, and he comes in and replaces it. I never have to mess with it.
Which solution did I use previously and why did I switch?
Our old arrays, the VNXs - we had a 5400 and a 5700 - were reaching the end of their days, and we wanted to go to the next step up, but not quite to the Xtreme level. Unity was the obvious choice.
When selecting a vendor, support has to be rock solid. And then, ease of use: Do they have all the features we need? Are there any outstanding issues that are going to clash with our onsite stuff (which usually ends up being with AIX)? As far as Dell EMC goes, we've been pretty good with them for a while.
How was the initial setup?
The setup process was pretty straightforward, similar to any other storage device. I don't think there were any special considerations we had.
What was our ROI?
We've only had it running for not quite a year yet. I can't say, versus our other arrays, if the ROI is better or worse at this point.
Which other solutions did I evaluate?
We only use Dell EMC and Pure for storage. We went with Dell EMC because of cost. We have an aging Isilon that we're also replacing. We do have Pure, we do the flash array there, but that's quite expensive compared to the Unity. What we needed was dependable cheap and deep storage.
What other advice do I have?
It really depends on your specific needs: if it's speed or if it's longterm storage. Dell EMC has a whole array of products. I would say go for it. We used to push the Isilon a lot, that's super cheap and deep, and that's been rock solid as well, but you lose that block functionality. You really need to go to the Unity. I would definitely do the Unity over the SC.
It was pretty easy to order. We got rezoned when Dell took over, so our sales rep is out of a different state. But, as far as going through our partner, it was perfectly fine, like any other normal purchase.
I would rate the Unity at about seven out of ten, once the bugs were fixed. To be a ten it would need native replication.
