Dell EMC Unity XT reviews

I primarily use the solution for NAS network storage for the Microsoft environment.

Overall, I've had a very good experience with the solution so far.

Integration is easy with this product.

Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment.

I've been using the solution for two months at this point.

We haven't used the solution for very long, so it may be hard to gauge the stability. However, so far, we haven't had any issues whatsoever. It doesn't crash or freeze. It doesn't have bugs or glitches. It seems quite stable.

Having only used it a short time, we haven't tried to scale it just yet. We don't foresee any limitations, however, without actually doing it, we can't really tell.

We needed to contact technical support in regards to an IAS error in automatic services. We didn't have any issues reaching them or getting the help we needed. So far, we've been satisfied with their level of service. They seem knowledgable and responsive.

We found the implementation to be very straightforward. It's not complex in any way.

The deployment didn't take too long. We had everything up and running in two days or so. It's pretty quick.

We have 12 technicians for the maintenance of all of our equipment in the enterprise. They would also handle any maintenance required for this product.

The pricing is quite good. We find it fair. It's not too expensive.

We're just a Dell client. We don't have a business relationship with the company.

I have four Unity products. Two were already installed in September, and one just last week. While two are already in production, the other two are not up and running yet.

I'd recommend the product to others.

Overall, I'd rate it nine out of ten. We haven't worked with it too long, however, everything seems to be going quite well.

We use it for ESXi data stores and performance seems to be okay so far. We've only had it a couple months. We have it integrated with VMware.

The benefits are the stability and that we're able to contact Dell EMC support for a quick turnaround. We have a higher level of support. If we have issues, they generally get fixed quickly.

Our hope is that they stay up, online, and that we will be able to update them while the data stores are operational. That is why we picked them.

Once it is set up, it is definitely easy to manage.

We've got an ongoing issue with a Unity in which some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR, which has been a struggle. It doesn't seem to affect performance but it's something that we're hoping the engineers can resolve.

We have also had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that.

The stability has been fine so far. We're good during normal operations.

In terms of scalability, the size is fine for the environment we have. We're usually at about half the capacity, so we have quite a bit more we can expand with. It's good.

In most situations, tech support works really well. If there are technical logs that they can diagnose and actually pull something out of, fantastic. If there aren't, if it's an abstract sort of issue, like the fan issues we're having, where they cycle every six minutes, it's taken me about six weeks.

They didn't believe me that the environment was not too hot. So they sent a technician out just to make sure that I could read the thermostat, that it was 68 degrees in our office. Then, they sent someone out to reseed each component, which I had already done. I didn't appreciate that part because I did some of those basics. I did exactly what they had said on the phone. The third time, they actually replaced some components and the fourth time they just sent the components to be replaced. It appeared to work, the fan issue did appear to go away, but it came back a couple of weeks later, after an update. I'm not sure if it's update-related, but it came back.

Because I've done the setup before with the VNXe version, it was straightforward. It's very similar to the VNXe.

Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out.

Study the configurations of what you need to use and ensure you understand what you're provisioning. The procurement process can be a little daunting because there are a lot of features and there are a lot of components that you'll get set up with but which you may not need.

When selecting a vendor, what's important for me are global, 24-hour support; being able to get things fixed. After that, price, because we'll probably buy a thousand of them over time.

We use it for our NAS systems and our SAN systems. On the NAS side, it's used for our end-users' home directories and Departmental shares. On the block side, we use it for VMware storage and we have it integrated with VMware. There was no additional cost for that integration.

We just started doing a bunch of automation where, if an end-user's home directory or Departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us.

Our end-users are happy with the product, there are no issues.

The product is pretty easy to use. The GUI is nice, really easy to use, and the performance is good. 

For the upgrade from the old system to the new system, if there was a better way to integrate them so I could easily move the data without working all those nights and weekends, that would be nice.

Also, Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product.

The product has been pretty good.

There was one minor issue where we would get these alerts every six hours, but they were fake alerts. We installed a patch a week ago and it fixed the issue. Other than that, no issues, the product has been stable.

We have a Unity 500, which scales to 500 drives, and we're about half full. But it's like their previous systems where you can add a couple of drives or a couple of shelves. There are no issues on that end.

Technical support has always been pretty good. Customer service includes the guys who come in and replace the drives and install the system, and those guys are good too. No issues.

We had the older generation of the Unity system, it was called EMC VNX. It's similar in some ways, but they've definitely improved the GUI, the user interface, and the performance.

When selecting a vendor, a big thing is support. We really need a company that, when something goes wrong, they're there and they can respond immediately, so we don't have to wait a certain amount of time. We experience a little bit of the waiting part with Dell EMC, but we have a technical account manager, and his job is to escalate. Since we already had that with EMC, it made sense to go with Dell EMC. So support would be number one. Number two would be performance, obviously. It has to work well.

The initial setup was pretty easy. We actually have a Dell EMC service engineer who came on site and helped set it up. I had to help in terms of getting all the infrastructure ready, but he did most of the heavy work.

The upgrading experience from our previous solution to this one is definitely better than it was with the VNX product. The only thing that we wished that it had is a way to migrate the data from the old system to the new system. We had to do a manual process for that. To move the data, we had to work a lot of nights and weekends. That was the hardest part of setting it up.

But other than that, it's better in every way.

I get fewer calls at night. That's my ROI.

NetApp and HPE were on our shortlist. HPE support is not good, so we didn't choose them. NetApp does have some good technology, but the relationship that we had with Dell EMC was the reason that we chose them.

In terms of the purchase process, we work with a rep. We have biweekly meetings. They're always on site. We worked with the Dell EMC sales engineer, making sure we got the right kind of drives, the right kind of performance, etc.

We use it for enterprise SAN. We have multiple units. We just started getting them in and the performance has been good. It back-ends our enterprise Oracle, which is for our financials. We have some Mission-Support applications that it supports as well. We have both structured and unstructured data.

The most valuable feature is the ease of integrating it into our current environment. It works within our enterprise management application. The NAS is also extremely easy to set up.

On the data domains - for the Unity product, but specifically for data domains - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily.

In terms of stability, so far everything has been fine.

The scalability has been pretty easy too, as opposed to some other vendors that we've had in the past.

We have only used tech support to replace drives that have gone bad. But our experience has not been so good. The biggest problem has been having the right equipment in the right category that our support people can have access to. We have multiple accounts, and unfortunately, equipment is across them. So we'll call it in and they'll say, "Well, that's not under your account," so they can't actually go in online and put an SR against it. We're working on fixing that, but that's been extremely frustrating. Once we get past it, and if they understand that, yes, we do own it, and where the site is, etc., getting the part is easy.

We are replacing our VNX2s with the Unity storage. The VNXs were end-of-life and it was our normal tech refresh. We also had new requirements come in for larger storage so we bought the Unity.

The initial set up was more difficult than the original VNX2s. My Storage Admin said that it was just different.

Three years is probably the best that we get for the return on our investment. It takes three years to actually get it back.

Regarding the licensing, that was easy. As far as recurring costs go, all that is understood, what we need to keep in place. If we grow and scale, we also understand a license comes with that, too. In terms of integrating it with our existing apps, there was no additional cost, nothing we didn't expect.

Primarily we're Dell EMC. We do have NetApp and they're pretty big, they're petabyte systems and they're primarily for a business-level project, not for enterprise storage. After using them, we definitely wanted to stick with Dell EMC.

It's a good product and you should definitely evaluate it. We're concerned about standardization, so even if a product has something that's better - one item, one capability that's better - we probably wouldn't go with it and would rather standardize across, for support and everything else. That's important to us.

For the purchasing process, we'll go to the vendor, we'll give them our requirements, and we'll work out the final design. They'll give us a quote and then we'll get two more quotes from two other vendors. We're required to get three quotes. I then put that in through my finance and then it goes through contracting. Contracting goes out and they get the true quote. And then, once the equipment is purchased, it comes directly to me onsite.

I rate the solution an eight out of ten. Improving the interface for managing it would help make it a ten.

Our use case is very unique. We just need it in our offices.

It used to be a complex product. Now, it is becoming simpler. 

Overall, the feedback from my team has definitely been positive.

• Its simplicity and simple management. 
• Auto-features for data protection.
• Being able to expand the product.
• The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning.
• The support for Dell EMC is excellent.

I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now. We tried it multiple times, and while the physical box is easy, when we mixed it with a virtual edition and it seemed very complex. We been trying this for several months, even with the cabling included. We are still working on it.

No issues so far. It is very stable.

It is scalable. We can always add additional tools if we need to expand it. 

We had been using VNX for a long time that it is now a part of our lifecycle. We introduced Dell EMC Unity into our environment to replace the VNX.

We contact our VAR, get a quote, and order all the hardware. Then, they ship and install it with a Dell EMC engineer. It is very straightforward.

We can see improvement since moving to the inclusive licensing.

The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered. 

We have worked with different vendors. However, right now, we are sticking with Dell EMC Unity as it seems like it is a very solid, mature product.

Do your homework. Obtain all the use cases. See what license you need and purchase the license as part of your preparation. Then, the process will be smooth.

We do integration with vSphere, but it is very limited because we outsource with IBM. 

The primary use case is block storage for ESX and structured data, SQL Database primarily.

We have adopted the all-flash array. It eliminates all the overhead of tiering and a lot of the data structuring overhead involved. It gives us a lot of operational efficiencies.

Being able to bring those multiple groups into a central solution. From a storage perspective, that is a bit of a challenge. 

There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing.

The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data.

We have never had any problem beyond that which you would assume you might get out of a storage system.

It will scale as much as we want or need. Scalability is not a concern.

We have not had to use tech support often, beyond the normal occasional drive, standard part replacement. The support has been good.

We've been a long time EMC customer. For us, though, it's been a journey of modernization and standardization. We took a couple different storage platforms and then centralized it on the Unity.

When selecting a vendor, from my perspective, I like to come up with the technically best solution possible, and then work retroactively into the price. Then, obviously, the business will make that decision based on price point and other things. But we try not make that one of the deciding factors.

My advice would be, if you're looking for this kind of solution, one of the challenges we had was clearly defining the use case. There is a lot of preparation in clearly identifying the workloads that you're going to put on it.

We have two all-flash Unity's and their primary use case is for VMware. We have two VMware's and the Unity's are the data storage back-end for them. We also have some 20 servers that boot from SAN, Fibre Channel. We also provide storage disks for the servers.

It helps because the all-flash feature is really boosting up the VMware. It is helping our virtual machines to perform better.

It's very simple to use. I really love the new Unisphere.

In a Fiber Channel world, things aren't really evolving, they're pretty stable. The VVols will be something that we'll look into later on. Now, we use very traditional LUNs that are attached to VMware as data storage, so we're not yet using VASA or VVol stuff. But maybe that will be something that, in the near future, when we update VMware to the next operating system version, we'll look into.

There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it.

I think it is really stable. We have had one Unity for two years and the second one was bought this year. I have roughly two years' experience and we have had no problems at all. Then again, we are only using Fibre Channels, so I don't know if the file side or the iSCSI side has issues. But the FC side is working very, very well.

The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go. It's an easier process to order them and to get more storage when we need.

We only used technical support during the installation. When we installed it, we had to fix some things with support. But after that, we have not needed to use it. DELL EMC support works really well with EMC storage systems.

Setup was very straightforward but, then again, I have a lot of experience with Fibre Channel. I've been working with two VNX machines, and with one Clariion before that. I've been doing this job for seven or eight years, so I knew exactly what I wanted. Our technical guy came and installed it and it was very, very simple.

When selecting a vendor, I really just want the product to work and the support to work. Every computer fails at some point. Every computer breaks down occasionally, and when that happens I need the support to act quickly and be as useful as possible.

I would give Unity a definite nine out of 10 at the moment. I really like the storage system. It's really good.

If you are using a fully virtual environment, I would suggest you check into an HC, a hyper-converged environment instead. But if you do need traditional storage and a SAN network, I would really recommend Unity as your back-end, if you're not too big to use Unity systems. They are mid-range storage. If you have a mid-range environment and you need to use Fibre Channel, I would really recommend a Unity All-Flash system.

It has improved the environments for many customers who have transitioned from other vendors storage platforms to Unity, due to technical proposals and offerings defined by us.

• The ease of management and “user-friendly” management environment (GUI).
• Simplicity for deploying and controlling storage elements.
• Ability to redefine storage policies and improve performance (adding dynamic cache and “Auto-tiering”).
• Hardware simplification (e.g., not requiring NAS dedicated hardware).
• The true “Unification” (to have a fully-flexible solution combining multiple technologies and protocols in 2U of rack space).

There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays).

It has evolved from what it was one year and a half ago, but there are more features incoming with the scheduled “UnityOS” updates (planned on roadmap) that will provide the product with new features only available in VNX2, but most important, all newly added features will have no additional cost for the customers, because the platform is fully-licensed from the base configuration.

Very few (some NAS related issues with early “UnityOS” versions, prior to 4.1).

None. Data-in-Place Conversions are available, for “scaling-up”. This feature may be driven online, in the next “UnityOS” release (4.2 SP1).

With the new support options offered with Unity, this support is always offered on a 24/7 basis (if the customer allows it, the system will be permanently monitored for issues). In this case, the system will be “two-way” connected remotely to Dell EMC proactive support via an ESRS gateway. Now, with the option to add a feature called “CloudIQ” that consists of an online portal offering (totally free, without additional fees) to access online and watch the system health and behaviour (in real time, from a customer point of view).

This does not apply directly to us. I had a very close contact with all “EMC legacy” storage platforms from the times of Clariion and Celerra. Thus, I have experienced the evolution and consolidation of these products, first on VNX, and later on in Unity, that is the pinnacle of this unification.

The initial configuration is guided by an “Initial Configuration Wizard” that is completely straightforward.

Absolutely. We offer Dell EMC solutions to partners who always work with several offerings from various manufacturers, targeting the same scenario (mostly NetApp, Huawei, HPE and IBM).

When implementing this product, be careful while configuring “Virtual Pools” (on hybrid platforms), in order to assure optimum performance. The proper disk raid choice is critical and may impact directly in the performance of a “Storage Pool” dedicated for a specific purpose or environment.

Dell EMC Unity is actually one of my market focuses, from the understanding that Dell EMC has redefined the core of their mid-range storage portfolio, focusing on two main products: Dell EMC SC (Dell legacy Compellent) and Dell EMC Unity (the last mid-range storage solution developed by the former EMC, just prior to committing the fusion with Dell).

In the Spanish market (which is totally different compared with US), it is considered the “premium” Dell EMC mid-range storage choice for those SMB customers who wish to acquire a full integrated solution, combining “multi-protocol” physical topologies (FC/10GbE) but also combining multipurpose storage (SAN/NAS and “Virtualization Optimized Storage”).

From this point of view, I consider it a “well-thought out” solution who was born from the principles that EMC established with the development of the VNXe Storage Series (considering that VNXe3200 is, in many aspects, the mother on Unity). It has inherited a full refresh regarding the “microcode” that characterized the VNX Series, while retaining all the benefits developed in the VNX MCx codes (optimized for true multi-core processing) and foremost developed (is the case of Unity AFA solutions) as a true “All Flash” solution, from their very foundations.
