Dell EMC Unity XT reviews

The primary use case is for our reporting environment, business intelligence and analytics. We run our Oracle and SAS-based applications on it right now. The performance is sufficient and we don't have any complaints about it. 

It runs our business analytics environment, so it improves reporting performance, how they pull data.

For our environment just having a solid, running box is really sufficient.

The administration of it is fine. For the most part, it is easy to manage. There is not a lot that you really need to change, there is not that much you really need to do. 

The Active Directory integration isn't very good, it is kind of limiting. It's okay.

When you get into more advanced storage administration, it's really hard to find that stuff, but those situations are few and far between, so it's not that relevant.

Also, I called about an issue where I couldn't get VVOLs registered. It turns out it is a bug in the code and that there is no information about when it will be fixed. It's just not going to work. I was a little miffed about that, especially getting more into VVOLs with Pure Storage, but it is what it is.

I would like to see better support for VVOLs and a less hokey AD-integrated login. Those are probably the two things that bug me the most.

I haven't had any issues with stability.

We did an upgrade not that long ago and that was a little rough. They uploaded the firmware and it seems it was corrupted. When they went to go live with the upgrade process they had to re-download it, which took a while. I didn't have any issues personally but I saw some of the trials that the support and then the engineering teams went through. It made me a little anxious, watching that process.

The scalability is fine. There's not much for me to really say about scalability. Adding disk is really the scalability factor, for right now. We only have two shelves of storage disks so I don't have any concerns about or needs for scalability.

Support was responsive.

I am not sure we've gotten to the point of getting a return because we've spent three years investing in trying to build out our SAS platform. I'm not sure we're there yet.

Vet out your use case sufficiently, make sure you understand what you are trying to achieve and how you are trying to achieve it. Do your best to leverage the gambit of functionality, as opposed to focusing on one area.

I rate it at eight out of ten. The best would be no issues, no concerns. I can't imagine I'd give anyone a ten, to be honest. To achieve that is pretty hard.

I wouldn't not recommend Unity.

Our Unity arrays are our primary storage arrays for both of our data centers. We run all our VMs on there, they're all-flash. They've been running great. We've had no problems with them. Fantastic.

The fact it's all-flash is why we chose it. The speed increase, therefore, that we've experienced from it has been great.

Obviously its speed is the main reason why we got it but we've really loved being able to use the interface. We've been able to create LUNs easily. We're able to get in there and create what we need, do everything we need to do, configure it the way it needed to be configured.

In terms of simplicity of ownership, it was almost plug-and-go. We did have some help getting it set up but, as for licensing and being able to get support through Dell EMC's site, it has been really easy. The interface makes it really easy to manage.

There could always be improvements to the UI. For what we've been using it for it's been great, but there are always little tweaks that could happen there.

It's been very stable. We haven't had any issues. I think we had a drive go out and it was quick to alert us and they made sure that we got it replaced without any failures. Everything has been great.

We haven't had to do any expansion on it yet, but I've heard that it's very easy and that, if we ever need it, it shouldn't be a problem.

We've used the technical support. They've been great. They have a good system to alert you when there's an issue. They've been quick to get us the drives that we need.

The initial setup wasn't too bad. They delivered it. We got the software installed, the OS installed, and got it all configured. It was just a matter of setting up the LUNs. We had a little bit of help with that but it was not difficult.

My advice is, obviously, to go with something tailored to your needs. For what this has been, a full flash array and ease of setup, from what I've had experience with, I would probably recommend the Unity array.

We plan to eventually use the VMware integration. There is a little bit that we're using right now but it's not the whole vSAN setup. I don't believe there will be a cost involved with that. It's just a matter of taking the time and getting it set up. Right now, we just have it set up as a simple SAN array.

Nothing is ever perfect. It would have to be perfect to be a ten out of ten, but this is probably as close as we've been to perfect, so that's good.

We're using it for block storage in a lab, supporting Fortune 500 customers, testing out solutions. We have a number of other competitive solutions in the lab and we try out upgrades for customers, we test out all the different features and functions.

Performance of the system is fine, I really don't have any issues with the actual raw IO of the system, but the competitors are pushing a lot of all-flash solutions in front of us.

We're not doing any integrated Snapshotting of the applications. Some of our team is working on being able to Snapshot Oracle RAC clusters but, for the most part, we're focusing on doing mostly backup solutions, data protection software.

It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended. There is a level of reliance and a maturity in the product, whereas the other ones are a little more cutting edge and the bugs can come out of the blue.

It still has the same implementation headaches of the VNX that came before it. It's still the same Unisphere, it's all the same tools from the VNX, nothing has really changed, from my perspective. It's still all the same stuff we're used to seeing. The management of it just isn't very strong, whereas a lot of the tasks I do day-to-day on some of the newer competitors, like Pure and Kaminario - we're talking three to five seconds to get something done rather than 15-20 minutes. It's a big time saver on the other systems. With the Unity, once it's installed, raw performance works fine.

In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful.

I don't know that I can really address the issue of scalability with the units we have. We have mostly a test box, a small one. We haven't had to add disk shelves or do any scaling of the system.

Unity is a lot like "no one gets fired for buying IBM." I think you will get what you pay for, but a lot of competitors have better efficiencies, better programs, easier installations. I'd be looking elsewhere. I don't feel the product is the leader in the market anymore.

I rate the Unity at eight out of ten. It gets the job done, it does it well, I can rely on it. It's just not cutting-edge in any way right now. To get to a ten, as I said, the upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore, and all of our customers feel pretty much the same.

We're using Dell EMC Unity as our primary storage for our production and for our DR site. We've had no performance issues with it, whatsoever.

We're using it for our data storage, for our virtual machines. It's the only array that we have, so we're not doing tiering at all. Everything is on the unit. We're using it for the data storage that we replicate to our DR site, for the ones that just stay local. We're using it for allocating raw disk-mapping, for mapping storage from the SAN directly to virtual machines for super-clusters and the like. We're using it for everything

The fact that it's all-flash has really helped our overall performance.

It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNs. We just have to add and configure the storage in one place and it takes care of everything, which is very handy.

Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that had deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have.

We've had almost no stability issues.

We had an issue once and it turned out to be a bug. There was a memory leak and we had an issue in our DR site where one controller would reboot and then come back up and then, later on, the other controller would reboot and come back up. Then it happened once on our production site where both controllers went down at the same time. We worked with Dell Support and they found a memory leak and they recommended we upgrade to the latest code version.

They have a script you run, a utility to gather the logs, etc., and then they analyze. The hardest problem was that, because they're analyzing logs, they have a certain SLA in which to do that. Even though we had a production issue and we wanted it resolved right away, it took them a few days to analyze the logs and get back to us.

We've added more and more on to it, and had no issues with it. When we started there, they had just deployed Unity. It was used in a few places, but not all that much. We've been migrating more and more over to it to get off of and retire the VNX, and we've had no issues. The compression has been working well.

We came from a VNX platform and we had lots of performance issues on the VNX, especially when we were doing OS patching. When all the reboots happened at the same time, we had performance hits on the VNX, systems crashed, and so on. And with the Unity, we have no issues. It's much easier to manage than the VNX. I've been managing both, but I've found the Unity is a bit easier to manage and to deploy.

From what I understand, the VNX was coming off of support and our company worked directly with our Dell EMC rep to see what was out there, what we could use, which storage arrays have which features, and they went with Unity.

To go with all-flash with Dell EMC, you've got XtremIO and you've got Unity. Unity is the type of array that you can size yourself and say, "This is how much storage I want," and you can add on in the future. With XtremIO, you're buying a set package and you get what you get.

Each solution is dependent on the use case so it's really hard to give advice without knowing the exact use case the person is trying to fill. But we're very happy with Unity.

I rate it at nine out of ten. If they added dedupe, that would get me to a ten.

It is for our production. We also have a second one for disaster recovery. We use it for our VMware storage.

It's done everything we need and we have had no issues.

Since we have gone virtual, we've been using the SAN and the speed on our servers has increased along with the time to reboot and time for maintenance. We have built in our company's backup redundancies and the SANs both have Unities with replication, which has benefited with speed and reliability.

• Speed
• Reliability
• Support

It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done.

If there's anything Dell EMC could do to get the same performance for a cheaper price, that would be great.

It's awesome. It hasn't missed a beat. We haven't had any issues with it whatsoever. Speed has been great. It does everything we need.

There has been no downtime. It has built-in redundancy upon redundancy, so I feel very confident with it.

I'm using 25% of the available space for that drive. I can scale it as far as money could spend, as far as I can tell.

Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed.

It's all been email-based portal cases. When they schedule remote sessions, they're on time. They get the job done and have been helpful every time I've needed them. I give them an A+ for support.

We were not using anything previously. We had 15 physical servers previously, so we knew it was time to change. This was part of a VMware virtualization project with SAN for the storage, so it made sense for us to go physical to virtual and use EMC Dell.

The initial setup is straightforward.

The vendor implemented it and is knowledgeable.

By doing virtual and reducing our footprint of servers, we're definitely not pulling as much power as we were. The time savings of not having to do virtual reboots rather than physical reboots of boxes. 

ROI probably has been more in time and uptime than in dollars saved. We have definitely had more uptime in the past year since we've been on this than we've had in previous years.

Dell EMC has a great portal for the licensing. It's very logical and easy to license. 

We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance.

When we were purchasing the product, we didn't have a capital budget for it. I sat down with my boss (the COO), and went over upcoming projects. We looked over the dollar values and if they fit. If it does fit, we do it. We went with the VAR that sold Dell EMC in our city and from there it was done. This made it very easy.

If it fits your budget, do it.

Most important criteria when selecting a vendor: brand and support reputation.

We primarily use it for backup.

It is a good backup product.

• It is easy to manage. A lot of the system manages itself.
• It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively.

• I would like to see more integration with other products.
• The interface can be a little challenging for someone new.

It is pretty reliable.

You can just add nodes and shelves to it.

The remote support is excellent.

We had a case automatically opened last night, and it is being handled.

Dell EMC has been around for a long time. Owning VMware is a big plus.

Most important criteria when selecting a vendor: 

• Support long-term
• Longevity
• Cost is always an issue.

We use our Dell EMC Unities to store the bank's data. We have one Unity in our production environment and another Unity at our disaster recovery site.

We use it in conjunction with VMware. We store all our virtual machines on Unity. 

The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data. It's also easy for us to use because we use other solutions which are built for Unity, like VMware, which are recovery points. They work with the Dell EMC Unity system, as these products integrate well in our environment. 

All our applications have been migrated to VMware.

It's very reliable. I have not had an issue with Dell EMC Unity. 

Their service is good. If there is an issue with our Unity, Dell will sometimes call me before I even know I received a notification. They will tell me that some disks are bad and needed replacement. Whenever we have issues, they respond very quickly. 

We are using all-flash disk, so the speed is very good.

The solution is stable.

We are a small bank. It is very scalable whenever we want to expand the disk storage. 

Dell EMC technical support is very good. I would rate them a 10 out of 10. They take you by the hand and walk you through every issue. They explain the issue and follow up on it.

Whenever we need help to service the system or apply any upgrades, their customer service is good.

We used Dell EMC for the setup. We had a Dell EMC engineer and a third-party engineer come in. The Dell EMC engineer came and set up what he had for the disk. He took away the complexity from us, so I didn't see it. We had a third-party help us as well during the installation. 

My part was mainly just administering the system. If I had an issue, I just made a short phone call to Dell EMC.

In the past, we used to have a physical server dedicated for Exchange or SQL. We have been able to virtualize those systems. Therefore, we cut our costs on the hardware and the backup is simpler in a VM environment. With Unity, we can easily replicate all our data to our production. 

For DR, the solution is very efficient for us. It has also allowed us to centralize our data repository.

While Dell EMC is costly, I don't have any complaints about their licensing model.

We have also used Dell EMC CLARiiON and Symmetrix within the Dell EMC shop. What attracted to us to Dell EMC Unity was its flash disk technology.

Outside of Dell EMC, we looked at IBM and HPE. However, we have VMware as a recovery point for replication, and those VMware solutions work together well with Unity.

The purchasing process was uncomplicated. We went through a third-party reseller who has a relationship with Dell. They know the product well, so they specialize in it. We gave them our needs and they were able to recommend the appropriate solution to Dell, the sizing, etc. This helped us out. 

We can sleep at night because the support is great.

We use it as block storage for a couple sites. 

The performance is fine for what it does. It is flash and spinning media.

For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed.

It is simple to use and easy to manage. We don't touch it after we set it up. It is not something you constantly have to go in everyday and tweak, which makes it beneficial.

• Ease of use: The GUI management is very easy to use.
• The management is easy for us. We rarely touch it now. It just runs.

I would like the UI to look better.

Stability is very good. It has been running for over a year now without problems. We haven't had any dropped layers.

The growth is difficult to forecast, but it's easy for the unit to grow when needed. It is very scalable.

The technical support does alright.

We didn't have a solution in place for the size that we needed to have a high availability solution. Dell EMC is our preferred storage provider, so we went out and worked with them to get a solution where we have a cluster environment to VMware and a failover with the other node along with shared storage.

The initial setup was very straightforward. This was not our first SAN array, so I just racked and stacked it, and they gave us the IPs and turned it over to us. 

The purchasing has been simple. When you do need storage, you spec it out. Then, you receive a quote back and make a decision from there. 

The last purchase was in China, so I was more on the config, less on the purchase side.

The solution should be cheaper.

We evaluated NetApp. We decided on Dell EMC because we are more familiar with them.
