Dell EMC Unity XT reviews

It is primarily for block storage for VMware in our Americas data centers, and it is also used for block storage and file storage in our European data centers.

It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster.

We use the all-flash arrays so the performance is probably the most valuable feature. As features go, deduplication and compression are important too.

I would like to see them add Storage Groups, like we have had in Clariions and VNXs. Storage Groups would be a great addition.

We've had no issues with it whatsoever, as far as stability goes.

We have not had to add capacity to them. I would imagine it's going to scale well, we just haven't had to add capacity.

The support is very good.

It was just a refresh.

When selecting a vendor, the criteria for us would be 

• track record
• stability
• support.

I work for a rather large law firm and they're not typically that price sensitive but, obviously, we need to be good stewards of the firm's money as well.

The setup was pretty quick, pretty easy.

At this point, I would give the Unity an eight out of 10. I think it's a little bit early on in the development of features. But overall, it has performed well.

There are some alternatives, but what we've found, working with our partners, for mid-range storage it's probably the best one you could choose. There are other offerings from other vendors, but it's a good choice.

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.

Mostly, it is used for the storage of a fertilization environment. It performs fine.

All the features are okay, but not all of our customers are using all the features.

The features are nice, but you can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity.

It is very stable. While I have had downtime, it has mostly been due to a bug in the MCX version.

Scalability is good.

Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react.

As a partner company, if EMC does not react immediately, it is not good. Because if there are any issues with the customer, then we need assistance. However, it is getting better and could be better.

The VNX is also a good system, but Unity is a little better. I am not saying it is much better, but it is better than the VNX. 

Just use EMC.

Most important criteria when selecting a vendor: 

1. The product itself.
2. How the product is used.

It saves us time, it does not require a lot of admin from us. We are looking for things that we don't have to spend a lot of time managing. This solution falls into that category.

It is easy to use. Setting up replication is pretty simple. We just set it and forget it.

I'm not sure if it has a single pane of glass management console. That would be something we would like to see. Managing as many platforms as we do, as many physical devices as we have, anything that can provide a single pane of glass would be a huge benefit.

We're happy with the stability. We have not had any issues with it. We run all-flash on two of them and, so far, we have not had any complaints about performance issues.

Other than upgrades, I have not had to use tech support. When I have had to do upgrades, they have been responsive, and easy to get to.

We are replacing our VNXs with it. Performance-wise, it has been pretty stable. The code upgrades are fairly simple and straightforward. I can't say it has had any issues so far. 

When selecting a vendor, product stability is the big thing, but support is probably right up there with it.

I would use this solution over most VNX solutions. It is right up there. We have some Pure Storage, so it is somewhat in contention with that. We are mostly an EMC shop, so that's probably our biggest deciding factor. If you're an EMC shop, I would definitely go with Unity. If not, which you go for will probably be in the middle. Pure probably has the ease of use down a little bit better than Unity, but I would ding their support much more than anything I've done with EMC. 

Easy to use. For beginners, it is very interactive.

The company migrated data from an older NetApp storage. The entire environment is virtualized. The amount of fast cache is great for meeting all demands.

All areas, since the entire environment is virtualized. In Brazil, price and native unity migration tools are not very good yet.

Still using.

No, but I found some articles about a code upgrade that solved some issues.

No problem. During installation, I added more disks and this activity ran without problem.

EMC technical support is great. With support, chat works well to talk with someone about any kind of problem. The only problem is some support agents take a lot of time to understand your issue.

I have worked implementing storage for at least 10 years. So yes, I used a huge number of solutions before. In this case, the customer changed because the warranty of his older storage expired.

The implementation went smoothly. The startup tool is very easy to use.

I believe there are other cheaper options, but you are not paying just for the "iron". The support in storage environment is a crucial thing to consider. Also, consider buying more flash disks for fast cache.

Implement views using consistency groups. It is easier to replicate LUNs, take snapshots, etc. Also, you can't use fast cache with SSD storage pools.

I have a few customers who are using Dell EMC products for storage, backup, and other different purposes. 

On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee. 

I have been working with Dell EMC Unity XT for three years. 

This product has been stable. 

Dell EMC Unity is scalable. 

This product does bring a ROI. As I have seen, it helps them to protect their investment since it is future-proof and scalable, so they don't have to change products every year or so. Because of those things, I have seen customers using the EMC product for more than three years. 

When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. 

Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible. 

I rate Dell EMC Unity an eight out of ten because, economically, there are a few things that Dell needs to improve. 

My primary use cases of this solution are to install storage and perform tech refreshment.  

The most valuable features of this product are its reliable storage and its archiving feature.

An area for improvement is the available capacity. If a customer goes with a base model, which would have its own limit, they could not go beyond the model-supported capacity, so an increase would be good.

I have been using this solution for two years.

My impression is that the solution is stable and reliable.

The solution is scalable to whatever capacity the model allows.

We have had customers reporting issues with slow responses from the support team.

The initial setup is a simple process, taking around half a day at most.

The pricing for this product is manageable, though slightly higher than comparable products.

I trust this product, compared to other vendors. It is best suited to small to medium-sized companies. When implementing Unity XT, make sure that the installation team is clear on the under-storage concepts and product knowledge. I would rate this solution eight out of ten.

We use it for both file and block in a converged system, supporting a VMware environment and virtualization. VMware is the primary use case.

We have deployed it at remote locations; in a converged platform it really helps. We don't have to have two different storage system which helps to minimize the footprint.

It is a platform that we have standardized on for remote sites which enables us to have engineers and admins who are trained on and knowledgeable about the platform across the board. That enables them to support those sites, which is super-beneficial for us because we can do more with less.

The ability to mix and match SSDs with flash, and spinning disk in there as well, really allows us to meet our performance requirements.

Overall, the most valuable thing for our use case is the flexibility to have multiple-protocol support.

We'd like to see a cheaper version of an all-flash array in that footprint.

It's very stable. We haven't had any major issues with downtime.

It scales very well. It's built into the model line which allows you to scale as necessary. You can choose the model you need to scale with your needs.

Dell EMC's tech support is awesome. We've used both onsite help and remote phone support and I have nothing but great things to say about them.

The setup was really straightforward. We have a long history of using the Dell EMC product line so we are very familiar with the platforms and how they work. This was just the next evolution.

I give the solution an eight out of ten because it meets our use case very well. But it's an eight because nothing is perfect. There is always room for improvement, whether that be in the UI or something else.
