Dell EMC Unity XT reviews

The storage solution has all our data from all systems, including our new ERP; the whole organization depends on the storage to work. All data is in one location.

Real Unified Storage (Block, File, VVols) in a unique 2U hardware. 

LUN mask. The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host. Storage groups or global IDs for LUNs could be a good solution for this.

No stablility issues.

No scalability issues.

Very good.

The initial setup was very simple.

The licensing process is very simple and it has many features. I can't talk about pricing because I'm in a technical position and I do not have access to costs.

Yes, we still have a VNX5400 (block), before it was at a production storage site, today it is at a disaster recovery site. The change from VNX to Unity was because of the build of the DR site, a new ERP implementation, and to update the storage technology.

Other storage solutions need additional hardware to support file storage and the integration sometimes fails; or they offer fewer features.

We were EMC partners for some time, now Dell EMC partners. Our choices are based in Dell EMC products because we understand that the EMC technology is better when it comes to storage solutions. Among the EMC storage options, the Unity is the best choice when we analyze price, scalability, performance and  features.

The Dell EMC Unity is a small but powerful storage solution. With the "unified" concept it is possible get many features for less.

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. 

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. 

This was for our SAN storage. Pretty much everything runs on this: databases, servers, etc.

We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint.

The software is very easy to use.

• Space
• Ease of use
• Snapshots
• Replication between sites
• It is very seamless.

We would like to see the synchronous replication process included in the next release. Not having this downgraded our performance by 65 percent. This really needs to be improved.

It is very stable.

It is very scalable.

The technical support is really good. I can open up a chat support session with them, then they can either resolve it or turn it into a ticket.

We previously had the VNX5700, which was seven years old. It was at end-of-life, and we had maxed out its capacity.

The initial setup was straightforward for the most part. Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication. 

We used Data Blue (previously LPS), as our integrator, to do the installation for our deployment. They worked with our onsite Dell EMC representatives.

Our costs are roughly $200,000 a year.

We narrowed it down to Hitachi and Dell EMC. We put it out to bid and Dell EMC won.

Overall, it is good product.

If you are doing asynchronous replication, this is a great solution. If you are looking for a synchronous replication solution, I would recommend PowerMax.

Our primary use case is for our data center and hypervisor cluster.

We can get almost real-time response times.

We are just getting ready to leverage Cloud Tier.

Deduplication is the biggest thing for our company.

It is easy to use.

Compression is making a difference towards the amount of hardware that we need to purchase.

We love our snapshots and the CloudIQ function is great.

I don't think we are really pushing our Unity, which we have discussed with Dell EMC.

I would like them to continue to build on the solution and expand on the functionality, like replication.

Our hypervisor cluster has 13 nodes. We have some file level and front-end services.

We leverage the iSCSI and Fibre Channel functionalities for scalability.

Dell EMC technical support is pretty quick.

We have it set up for storage for VDI. It is as advertised: Very easy to set up, very easy to manage, and the performance is great. We have integrated the solution with Horizon VDI and there was no additional cost to do so.

I don't have to spend nearly as much time getting in to manage the device on a daily basis because it functions very smoothly. We don't have any issues with it. Usually, on a daily basis, we don't mess with it. It's been hands-off since got it set up and configured. It's been great.

The ease of setup and management have been the best features.

The only thing that could improve it would be a price reduction.

It's very stable. We hardly get into the device itself to manage it on a daily basis. It's been great.

We have not had to scale it yet but, from what I have read and understand, scalability will be very easy. Adding extra bricks or nodes to it is going to be easy.

We haven't had to use technical support.

We had a previous storage device that was coming to end-of-life and we wanted to replace it. We had to do it in a very short time, last year. I liked the performance and the features that the Unity had. The cost was also a factor in our choice.

The most important criteria when selecting a vendor are that they need to be an industry leader, they need to be easy to work with, and they need to be fast. A lot of times in IT, we move fast. I need quotes fast, I need demos fast. That's one of the things that Dell EMC has always done for us. Those are a few things that we look for.

The initial setup was very straightforward. We had a Dell EMC technician on site to help us. He was very helpful, explained what he was doing, let us get hands-on when we wanted to be and could. It was a very smooth process.

Our shortlist also included Nimble. 

So far, it has done everything that they say, in demos, it will do. I cannot stress enough how simple and easy it is to set up and use and manage. That's it.

Regarding simplicity of ownership, everything that we've experienced so far has been very easy to deal with. We already have a Dell EMC rep who handles all of our licensing and notifications, keeping us up to date on that. Management of it and service have been very positive, nice and simple.

It was also very easy to order. We have had a relationship with our Dell EMC reps in Kansas City for the last 12 years, so getting in touch with them, having them come out and demo the product as best they could, and then getting us the pricing, getting it delivered - everything was very simple.

I rate the Unity at eight out of ten. I don't think it's possible for it to be ten. They'd have to have someone from Dell EMC show up and do my job for me to get it to a ten.

It helps our customers save money because it's at a price point where a lot of our customers can easily bring it in for different projects and it will also provide for DR. I find that the cost has really enabled them to do a little bit more with it.

It performs great. Customers really like it. I've had a lot of customers go from the previous platforms up to Unity. They've noticed better performance with it.

What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle.

Ease of management is one thing I get a lot of good feedback regarding as well.

The flexibility is also important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well.

I would love to see more compatibility between the different platforms within Dell EMC's portfolio.

Stability is great. It has been very rock solid.

Now that they can do the controller upgrades, it's really helped them out a lot, and it'll help to be able to scale more. They're not just trapped into one model and, instead of having to do a lift and shift of all the data, they can now do head upgrades.

The support is still going through its growing pains right now, with the merger of the two organizations.

I rate it an eight out of 10. It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers. We can overcome it, but it's a hard conversation to have with them sometimes.

Go in open-minded. If you're used to the old VNX platforms you'll be pleasantly surprised.

It can improve your TCO. When you buy a Unity box, you can consolidate a lot in a very small frame. You can save energy and, if you're arranging a room for your equipment, it can help you reduce costs in tiles and flooring, energy, and so on. It is pretty easy to use, so your storage admins don't have to put a lot of effort into managing it. It's easy and practical to use.

I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers. That is something that is much better than the expectation that we have with VNX, which does that post-processing, and is not recommended for databases. So it's a big step for Unity. When we position Unity, that is one of the first things we say, that it is prepared to work things inline with dedupe and compress.

I believe this product lacks some things that are extremely valuable for customers, especially VNX customers. The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems. That has caused us a lot of problems. 

The other problem I have with the NAS capabilities in Unity is the WORM feature. We were working with a government company that has a public bid and they were buying storage for 13 remote sites. All of them required WORM. Since this is a government customer they took two years or so to establish the project. And they required the WORM feature to securely store records, and they had to be unmodified records. They bought that the idea and they implemented a NAS solution that was going to be consulted by an Oracle Database. They had to buy VMX because Unity didn't have WORM. That would be the most important thing. It's very problematic.

Migrating from VNX to Unity was not so straightforward in the beginning. You could not migrate NAS servers from CIFs. They began with NFS. they recently added CIF support. So, lots of problems there.

I would say it is stable now. Of course, the first releases had some issues but I believe it is fine now.

Peru is a very different market from the U.S. or Europe. A company that is mid-range in the U.S., for instance, could be using an enterprise solution in Peru. For Latin America in general, it is a perfect product for mid-range and for some enterprise-grade, big, transactional businesses.

Technical support is pretty good. It always has been. In Peru, we have a senior engineer that has been with the company for 32 years. He has a lot of knowledge. We have three field engineers. For a small business, like the Peruvian one, it's more than enough, because these machines never fail. You just turn it on and that's it.

We had some issues installing these machines at the beginning, but overall it is really easy. It's done exactly the way the manual says.

I would rate Unity a seven out of 10. I know these products since Clariion, and I believe they hit a great peak with VNX2. It was a product customers loved. When Unity arrived, the ability to consolidate NAS and SAN in a 2U box was pretty cool. But the NAS part didn't follow. That's why I give it a seven.
