Dell EMC Unity XT reviews

We added it to our Vblock 740 as a storage extension, basically a tech extension for a capacity upgrade. We set it up about three weeks ago. I haven't seen any issues so far.

What we noticed was that the SP utilization is quite high, although the main load is on a VMAX. We'll need to dig into it with EMC and see if there are any issues that might pop up.

The setup was quite easy, straightforward.

Compression, it's an all-flash Unity, so with that compression feature, it's comparable to a hybrid. That is one thing that we definitely like.

It runs. No stability issues.

If those SP utilization things, noted above, get to be an issue, I think scalability might be an issue too. But we need to confirm that. I don't know yet.

We had a licensing issue to do with encryption but, other than that, we have not had to use tech support. It took a little bit, support had to get it into our ELA. It worked out in the end.

Obviously, it is the successor of the VNX. We wanted to add some mid-range capabilities to that Vblock 740 and it was the logical choice.

In terms of selecting a vendor, we're a big EMC partner, so we don't usually look at other vendors. We have very good experiences with EMC support so far. We are currently not looking at other vendors.

It is definitely worth having a look at. The price-point for all-flash is certainly quite interesting. It has NAS capabilities too, if you need it. It's an interesting product, at least for mid-range.

I provide support for these storage products.

I like that the performance is very good.

It would be better if there were more integrations.

We have been using Dell Unity XT for two and a half years. 

Dell Unity XT is a stable solution.

Dell Unity XT is a scalable solution. 

Technical support is very good. The response from technical support was very good.

Depending on the hardware, it takes about three to four hours to deploy this solution. 

We sometimes use third-party help because we are facing many hardware issues.

We have to apply for a license for each system. 

On a scale from one to ten, I would give Dell Unity XT a nine.

Unity is our central storage solution. All of our data is stored on this platform, so it's not just production servers in DR. We have two DR—near and far—so there are three sites in total. Unity holds all of our transactional data.

My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us.

We've been using Unity storage for almost 10 years.

Unity is very stable. 

Unity is scalable. 

I would rate Dell EMC support seven out of 10. We had to follow up a lot. We sent an email beforehand, so they knew the model and everything about our environment. We expected them to do better homework and engage with my team. If they had done the implementation like that we could have saved a lot of time. That is why I rate them seven and not nine or eight.

Implementing Unity isn't straightforward, but it's not that complex, either. There is still some room to expedite the implementation process a bit. We had support from EMC guys in India or Singapore. They worked with our bank's in-house storage team, which has about four members. 

Our contract included training, and we had to pay for that also. It was supposed to be on site, where our team visited EMC somewhere in India or Singapore to get training, but we couldn't do that because of the pandemic, so the training was online. If we get trained next time, we would like to do most of the implementation by ourselves.

We have a perpetual license for Unity and a support contract with Dell EMC. 

I rate Dell EMC Unity XT eight out of 10. We compared Unity with NetApp and HP also. In some areas, NetApp and HP have advantages over EMC. I think NetApp holds the top Gartner position. It's in the upper-right quadrant. 

Also, Dell EMC doesn't have a presence in Bangladesh, so they work through local partners. Previously, they had only one partner with sub-partners or sub-agents. This complicated the relationship with the end customer. We had been working with the same partner for the last eight years, but when we were upgrading, they told us they could no longer support us because they had some issues with EMC. We got caught in the feud between Dell EMC and their partner.

We had to get somebody else appointed as a new partner and then discontinue the earlier partner's agreement to make it commercially feasible. I think EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer. 

We have different models of VNX and we have Unity. We use them for file sharing and for block serving in non-production systems.

We don't have a dedicated application running on Unity, but we are using it and file sharing to run multiple systems, but it is not the core. It's used by a lot of applications, but we use it to share files between different applications on different platforms.

We have multiple systems, a heterogeneous environment with Unix and Windows. It's not easy to share multiple files through different platforms. Unity solves this issue.

Also, replication gives us high-availability, and thus quick recovery, and snapshots give us faster recovery within the box, in case there are problems within the box itself.

The valuable features of Unity include:

• it's flexible
• friendly user-interface
• good performance.

It's not complicated. Any beginner can work with this environment.

It is not an enterprise-level solution, it's for mid-range companies, but it includes a lot of features like compression and encryption.

If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced.

We cannot compare the stability with VMAX or PowerMax, but so far, so good.

The scalability is okay, it's fine. It's not powerful though. We have another product that is more scalable than Unity. It needs to be able to scale out, like the Isilon system and other systems.

Dell EMC has one of the best support organizations, worldwide. We have multiple vendors, but Dell EMC is one of the best. Regardless of whether it's Unity, VMAX, etc., it's fine. We have had very special support from Dell EMC.

We have a good relationship with multiple vendors, but especially with Dell EMC, which is one of the big players. Our main storage is Dell EMC for many reasons. We got Unity because we are happy with the support and with products like VMAX and Isilon. We didn't want to change the technology we are going with.

I was involved in the initial setup with my engineers. It was straightforward. Most products from Dell EMC are straightforward to set up.

We use it for our primary storage platform. All of our primary VMs run off of it.

We went from two boxes that were 8U down to a 2U box. Dell EMC Unity XT reduced the electricity we were using just by making that one change.

On a performance level, with SQL querying, it would take 60 seconds. That doesn't sound like a long time, but when people are staring at a spinning icon they can get outraged. This solution has cut it down to about 22 seconds for a query, so it's a lot faster. The difference was astronomical. We were using an EqualLogic, a hybrid array which had spinning disk and SSD, and the Unity just blew it out of the water.

When it comes to provisioning and management, when you compare Unity to EqualLogic, it's night and day. The EqualLogic wasn't nearly as flexible as Unity is. Once we saw what the Unity was capable of, there was no going back to the EqualLogic at all.

It gives me flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it.

I like the fact that it comes with a cloud option out-of-the-box. Just purchasing it gave us an unlimited amount of storage. It allows us to dip our toes in without a major commitment. With AWS or Azure, you're locked in and you're using up the contract and you're always worried that you'll spend a lot more. The use case for us would be disaster recovery or cold storage.

We use our VMware Site Recovery Manager and we use the device to replicate all of those hot VMs over to our DR site. We've actually tested it and it takes 19 seconds for us to get a virtual machine up and running, in the event of a disaster, because of the replication between the two systems.

What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps. But I'm thinking, "It's on there. It should be able to tell me this is the one that's eating up the bandwidth."

We've had no issues with the Unity. We haven't had a failed drive yet.

We haven't had to scale it out. We're going to scale it out next year.

We went from a spinning drive array because we needed something faster. We moved our analytic server over to it and the Unity was able to overcome the bottleneck that the previous storage had caused.

Also, EqualLogic went end-of-life, they weren't going to support it anymore. That was our initial driver. But we found we could fix some other issues with the move to Unity.

The initial setup was pretty straightforward, or at least we thought it would be. We have some complex stuff that we do on our network which caused some issues with it. That didn't make it a standard, out-of-the-box setup. Had we had a less complex network, it would have been a lot simpler to put it in.

We used a reseller and our experience was fine. It was not the first time we had actually worked with that reseller. We ended up having to engage with the Dell EMC people to get everything set up right. It wasn't the smoothest of introductions.

We looked at all-in-one, hyperconverged storage. We decided not to go that route simply because we've made such a huge investment on the networking side. If we had gone the hyperconverged route we would pretty much have had to rip all that out.

Then we looked at Pure. In the end, we'd been partners with Dell EMC for so long that it didn't make sense to venture out into some unknown when we were talking about the main platform which we were going to build all our VMs off of.

Find out your needs before you look at your options. Everyone's going to tell you theirs is the best but you need to know what you need going in, and what kind of performance level you need. If they're not willing to do a PoC then don't do it. If they're not willing to put their product out there and compare it with another product, then don't even consider them.

I would give it an eight out of ten. It has some deduplication to try to reduce some of the overlap that VMs, by nature, have. But I feel that could be better to try to save on storage. Also, better reclaimed-space management on it would be nice. Reclaimed space on virtual systems can be a pain to manage sometimes.

We use it for mass and block storage. 

We have not had issues nor performance problems with it.

It has saved us time when provisioning new storage, so we're trying to automate that process.

It's pretty easy to use compared to the older version of the product, which was called VNX. This product is way easier to use.

It performs well. 

They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use.

Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that.

It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual.

The stability is fine.

We haven't really upgraded yet, but I know we can scale to about 500 drives with the system that we have. We are about halfway full. The scalability seems fine.

Technical support has been good and responsive. They know how to fix an issue.

Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system.

The initial setup is straightforward and easy.

Deployment was pretty easy. We had a guy come in who did all the work.

Licensing is fine. We worked with a sales rep to purchase our Unity.

It's a good product.

We use the product with VMware, and also use it with Syft for home directory and departmental shares.

Most important criteria when selecting a vendor:

• Support.
• How long the company has existed.
• Is it an established company and product?
• Performance.

We use it for post to all our data stores or virtual environment.

We have had no performance issues. 

As far as benefits, Dell EMC Unity XT gives us fast access orders for everybody in accounting, and it's working. It is all-flash and is in extreme hyper-performance mode. 

When there have been critical updates, we will get phone calls from Dell EMC saying, "We need to update this, and because our contract support level is here, we can do this for you." They will bug you to death until you have updated it, which is good because we are overwhelmed.

It's all-flash.

The solution is so easy to manage that I forget it is there.

Their support is now a lot better, so that is good. They are very helpful when we called in and say, "This is the project that we want to do. Which box should we go about buying? They will send us the information and go through it with us."

We have had issues with the capacity and some misunderstandings on how much compression that we should be able to see out-of-the-box. When we were originally sold the box, it was before the merger. The salesman promised us at least a 50 percent compression on the box, so we ordered it with 2TBs of storage. That was a mistake, because now we are locked into smaller drivess. When it comes down to it, we are running out of space. 

We realized that were barley getting a 12 percent compression offset, not the 50 percent, and this came about the time of the merger. All of this was happening and a lot of people in the company did not return emails at the time. I guess it's because they were no longer with the company or they knew they wouldn't be, that's just speculation. However, it took us several months and almost ruined the our reputation during that time period. They did make right on it and sent us several drives to double the storage on our devises for free, so they made it right towards the end, but it took a while.

The iSCSI and the VMware integation using vSphere could be less confusing. 

Three to five years.

The box has been on 24/7/365 with the exception of one day when we had to change out the batteries in our battery backup. We realized our network cord was not working in it. 

When I left to come the conference, I looked, and uptime on the battery said "527 days".

You only have so many days in the storage. When you buy storage, buy more than you think you'll need, because it will come back and bite you. Because now, if we expand anymore, we will have to buy a box to piggyback on this storage. Hindsight is 20/20, but all-flash is expensive.

Technical support is much better now. They are  responsive, and it is easy to get to the right person. They will blow up your inbox and voicemail if you have a critical update that needs to be applied to either the drives or the box itself, which is great.

Previously, all our servers were running one instance of Windows, and running as a particular application. Email servers were on a server unto themselves. We had a mess. We had so much hardware. 

Because of Dell EMC Unity, I was able to turn off the server that I had been managing for ten years for email. This makes the server room a little quieter now!

We bought the box of all the licensing that we needed and not run into anything where we would need any additional licenses from Dell EMC Unity.

VMware is a different story, but as far as Unity goes, it's not been an issue.

Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government. So, we are lucky there. We have that working relationship with the folks at Dell EMC, and sometimes I even get to run into the rep or specialist at events, which is great. I don't get that with a reseller.

We also looked at iXsystems. We just purchased one of their boxes for storage. I've known iXsystems for a number of years, and they gave us a great price on an absolutely insane amount of storage because all we needed was a box set in a bunker for local backups. The Unity was just outrageously expensive for our needs, so we went with iXsystems. I've managed an iX box in the past. Those guys will bend over backwards to help you as well. So, that's why I chose to go with them.

Spec it out with bigger drives than you think you will need, because when you do expand, you're going to wish you had done that. If you buy bigger drives than what you currently have in a RAID, now you have to have a separate data storage. You can't have one continuous data store. For some people, that might be okay, but we really didn't want that but we were forced into having that.

We do integrate with vSphere. We tried Hyper-V and immediately regretted that decision and went back to vSphere. Right now, that is the only utilization and there are costs involved with the VMware integraton.

Most important criteria when selecting a vendor:

• Reliability
• The willingness to make it right when something goes wrong.

It's our primary storage array. We have a public cloud hosted internally, and it's our primary storage array for our customer virtual machines. It has performed very well. There have been no problems with it. We've had it for about nine months and it has performed well.

Obviously, our customers rely on us for uptime. We've had no problems with it so far. Migration to it went very smoothly, so in terms of value to us, it's been very good at keeping our workload and our uptime going.

Also, it has definitely provided much faster performance.

Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much.

The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier.

The interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage. We already had solutions in place, so it was more just a matter of buying the hardware and migrating workloads over to it. There was no cost other than the purchase of the hardware and software licenses.

We had a couple issues, but they were very minor, related to storage Snapshots and our backup product, which is Veeam. That turned out to be a Veeam issue.

My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be. They were very limited in scope. They could have been more detailed.

More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial.

It's been very good at scaling when we've needed it to. It's been a good solution so far.

We have used technical support occasionally. There really have been no issues, we haven't had it that long. But just for implementation and licensing, we did contact support a couple of times. There were no issues with it. They were helpful.

We were using a VNX array, which was fine for the time when we had it, but we've expanded. The business is growing and we decided to invest in something a little more heavy-duty to handle the kind of IOPS that we're dealing with now. We are a Dell EMC partner. Obviously, that is who we wanted to go with.

The most important criterion when selecting a vendor is their relationship with us. In addition, easy use of the product and reliability are important. We rely on uptime, so we look for redundancy and reliability.

I didn't install the hardware, but I definitely assisted in setting it up: migrating workloads to it, setting up data stores, etc. The process was pretty straightforward. It was stuff I've done a hundred times before, so it was what I expected. It was not more complicated than what I would have hoped for.

We don't have many numbers in terms of ROI because we've only had it about nine months, but we definitely see the performance value.

We looked at a couple. We looked at Rubrik a little bit and we looked at some HPE arrays, but we decided to go with Dell EMC to keep up our partnership with them.

Ownership simplicity is there. Licensing was straightforward. We've always had good support from Dell EMC, we've never had a problem with them. Their solution engineers are always very helpful. So overall, no problems with ownership.

I give the Unity a nine out of ten. The Help files and a little more integration would be nice.
