Dell EMC Unity XT reviews

We saved money by moving off old storage and we gained extra capacity and speed.

• I appreciate the great performance with flash drives, 12Gb SAS connections, and the 16Gb fibre channel.
• I like the easy management with the new Unisphere management and the HTML5 interface.
• All this comes with a smaller footprint, with the main unit taking 2U instead of 8U.

The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools.

I did not encounter any stability issues.

I did not encounter any scalability issues.

Technical support was good. I can create a case online or have a chat with an EMC support engineer.

We used to deploy EMC VNX. But we needed more speed and capacity.

The initial setup was straightforward. Disk Array Enclosure (DAE) cabling is different than VNX. Otherwise, it is easy.

Licensing is easy since all the software is included.

We evaluated Nimble, NetApp, and Compellent.

I recommend that you purchase five years of maintenance up front. EMC tends to increase maintenance significantly in years four and five.

We prioritize performance-driven systems. The Dell Unity XT delivers excellent performance and offers support services.

I always look at performance and quality. When we deploy solutions that work well, we directly help our customers improve their business operations. The only thing that might change my mind about the Unity XT is a product with comparable quality and performance at a lower cost.

I like its performance and support. 

There is room for improvement in manufacturing. 

I have been working with this solution for three years. My support contract is for five years.

It works fine for me. I would rate the stability a ten out of ten. 

It is highly scalable. There are around 200 end users. 

I would rate the scalability a ten out of ten. 

The customer service and support are good. 

Positive

The initial setup is not complex. I would rate my experience with the initial setup an eight out of ten, with ten being easy. 

It took a day to deploy the solution. This Dell Unity XT system is deployed directly for a primary customer of my company. So, our company works directly with Dell.

The deployment was done with the help of the integrator. One person was enough. 

Overall, I would rate the solution a ten out of ten. 

We are customers of Dell and I'm head of the team.

I like that you can add volume and it is automatically registered in VMware. It's easy to integrate XT with other solutions.

It's not a feature, but I'd like to see licensing costs reduced. 

I've been using this solution for a year. 

The solution is stable. 

I haven't tried scaling it because my work is a fixed requirement but it seems to be scalable.

I previously worked with Sequel Logic and a little with NetApp. We switched because it was a natural upgrade. I don't think either of those solutions is better than XT. I like it a lot although I think Unity does a pretty decent job as well.

The initial setup was straightforward and I think it took a couple of days. 

I think everything is overpriced in the storage area so it's difficult to know what reasonable means for these products. 

I rate this solution nine out of 10. 

Dell EMC Unity XT is used for virtualization storage mainly with very few files and very little power consumption. We have on-premise deployment on our own organization. We have two Dell EMC Unity XT, and four IBM FlashSystems for our own consumption.  

Nowadays we implement Dell EMC Unity XT less and implement more Dell PowerStore solutions.

Dell EMC Unity XT has good integration with VMware.

I have been using Dell EMC Unity XT for many years.

Dell EMC Unity XT is stable.

The solution is scalable.

We have approximately 120 users using this solution when combining all the customers we have. If our capacity requirements increase we would be increasing the use of this solution.

The support from Dell EMC Unity XT is very good here in South Africa. It is important for us. 

The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM. 

I am certified to do the implementation of the solution.

There is a license required to use this solution, but it is a one-time purchase.

The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance.

I have evaluated Pure Storage.

I would recommend this Dell EMC Unity XT to others. Overall it is a stable versatile solution.

I rate Dell EMC Unity XT an eight out of ten.

It's our primary storage. It is just for VMWare with a lot of Fail Over clusters.

For our mission critical applications, we run SQL, Oracle, Fail Over server clusters, VMWare, and databases. We use it for our primary VMWare environments, with a VPLEX, just for failover and performance. We use it for Windows Plus! because you need shared storage. In addition, we use it for healthcare systems.

We only use it for block storage. We don't use any other features. We have a VPLEX for applications.

Unity is supporting the organization, but it's not improving it. It's just hosting the applications.

Simplicity: It is ease to use. It performs. It's easy to provision, and It's stable.

I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool.

The stability is good. We are very happy with the Unity.

It does what it says it does. It performs, so you never have performance problems with it.

It scales, but then you have to buy additional stuff. So, if we need it, we can scale it. That is not the issue. However, we don't need it to scale further, because when I scaled it down, there are multiple platforms that we will move off the Unity to a hyper-converged or Isilon solution. Scalability isn't that important.

The technical support is good.

It's quite straightforward. It's deciding some IP addresses and building a storage pool, then you're off.

We always buy it with implementation services. However, we did the implementation ourselves.

With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity.

We had VPLEX, and it's a good merge with Unity. So, we didn't look very much further.

We also looked at HPE and Hitachi. We went with Dell EMC since we are a Dell EMC house.

It does what it needs to do that is the reason why we bought it.

We are not interested in the cloud option.

The primary use case is mid-tier processing for our hospitals. We have a lot of VM infrastructure on the Unity, but not our most mission-critical. The performance has been great.

The biggest benefit is where it fits in the cost profile. It's for VMs that, again, aren't mission-critical but do need some performance. It fits really well there for that. We get exactly what we want from it, what we expected.

The replication is big for us.

We use file services on Unity and it has a really nice file services interface.

It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy.

The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed. If it's on, it's on. So we have to be a little more WAN-sensitive, in some applications, which means we can't put it everywhere. That's the biggest issue for us, by far.

The stability has been very good. We've had it for a couple years, really like it.

Scalability is also really easy. There are lots of options.

Our experience with technical support depends. That mid-range is probably not the strong suit in terms of Dell EMC support. They don't have the depth of technical experience in that area like they do with some of the other products. But we haven't had any serious issues with it.

This was a VNX replacement. We had an older VNX that was off the depreciation tables and maintenance costs were a little higher, as the equipment aged. We just replaced it, pretty much one-for-one.

When selecting a vendor, a big factor for us is the quality of support.

The initial setup was really straightforward. I've been doing this for a long time so there were no real surprises in terms of the Unity.

The ROI is right where we need it to be. It's a reasonably priced array. It performs a function that we absolutely need, and it definitely fits where we want it to be. We wouldn't use it for everything but, where we use it appropriately, it makes a lot of sense.

This one came down to either Dell EMC or Pure. We had a NetApp as well, but we weren't considering that. Pure doesn't really have the depth of product offering, so this was an easy choice for us.

I would definitely recommend it and have recommended it. We're pretty large, but I think for most companies it probably is the array that's going to work the best, especially for a VM workload. If you don't want to invest in a VMAX, this makes a lot of sense.

It fits that price profile really well. It's an entry-level, all-flash array for us. So stuff that we don't want to go on VMAX or XtremIO, we can put right on the Unity and feel pretty comfortable that it's going to do what we need it to do, as far as performance goes. Unity falls right in, with it being the successor to the VNX line. It works great, has a very simple interface that we're comfortable with, so it's a good product for us.

In terms of the purchasing process, we have a pretty good sized environment, so we work with our dedicated team. They knew that this was going to perform the way we wanted. We had a spot where we needed some VNX replacement and this was the logical choice. It was very easy.

My rating of eight out of ten would get to a ten if it had throttled replication.

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.

Most of our customers use it on-premise, 90 percent of our customers use VMware vSphere on top of it, and a little more than half of them use Fibre Channel to connect to the Unity. They use it for most of their workloads.

Our customers have a competitive edge when compared to the other solutions in the market. Most of our customers don't just look at the value per Gig, they put a great value on the after-sales support and the stability of the appliances.

It's the simplicity, and most of all it's backed up by Dell EMC support, which is very valuable.

There aren't any improvements that come to mind, none that are obvious. After what I've seen today, here at the Dell EMC World 2018 conference, they pretty much have the next couple of years covered. For example, the current buzzword is the Cloud Tiering Appliance which allows you to tier data from your on-premise to the cloud or on-premise cloud.

To me, the stability is impeccable.

Scalability is good.

Tech support is very good, very efficient.

Setup is straightforward. Once you do it once, it's a walk in the park.

The backing of the vendor is important. In Dell EMC's case, we know that there is always someone backing us, just in case we get stuck.

A rating out of 10 out of 10 is a bit too much because, obviously, no product is super perfect, but I would rate the unity a good nine. What might make it a 10 is a better price.

I would vouch for this solution, I would definitely say go for it.
