Dell EMC Unity XT reviews

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.

We used Dell EMC Unity XT for onsite storage.

We were moving from our HP3 power data center to a hybrid cloud solution. We still needed some onsite storage, but we wanted faster performance and a more efficient capacity. The flash storage generally outclasses older solutions, which was why we went down the flash storage route.

Having gone down the flash storage route, we liked Dell EMC Unity XT because of its speed and efficiency. We did compare it with Pure, but we liked Dell because Pure is more niche, while Dell EMC Unity XT is more general purpose. We can also buy other things from Dell, and we get better prices from them, compared to Pure. In Pure, you can only buy storage. These are the things we liked about this product.

Dell operates at the commodity end of the market, so if they really want to get into storage in a big way, they need to have better pre-sales technical support and engagement.

They do what they say, but if it was a really big implementation, I would be worried about recommending Dell EMC Unity XT, simply because we need to have a more technical understanding of it. The technical engagement can be a lot better.

Dell EMC Unity XT is a stable product.

Dell EMC Unity XT has good scalability.

The technical support for this product is fine.

There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage.

We evaluated Pure Storage.

I'm in IT and my niche is digital transformation consulting. One of my customers needed a storage solution, so I recommended Dell EMC Unity XT. I'm not a storage consultant. I'm a digital transformation consultant, and one of my clients needed a storage solution.

I'm not a user of this product. My clients might need a solution from time to time, and what I do is I recommend solutions.

Dell EMC Unity XT is a good product.

I didn't get involved in the initial setup of this product, but I believe it was straightforward. It only took one to two days for the installation, then we were able to migrate our data.

I can recommend this product to others looking into implementing it.

I'm giving Dell EMC Unity XT a score of seven out of ten.

One advantage was the ability to use different types of disks and different types of disk solutions to increase the speed, first of all, and to take advantage of different storage costs across the life cycle of the data.

• One of the most useful features for us was the deduplication. It had been challenging for us to store certain types of data and to use patterns of storage to reduce storage size.
• The IOPS and the speed were also an important part of the solution.
• In addition, there was a Unity machine that offers block-level and NAS, and we used the block-level storage.
• We also use the side-to-side storage verification for the recovery site.
  
• Finally, the device was flexible and we could change the configuration to meet our needs.

Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things.

I worked with Dell EMC Unity XT for two to three months. My last role was IT director so I didn't do a lot of hands-on with the devices. I was overseeing the IT staff and doing project management for these kinds of solutions. At that time I was working for a manufacturing company for pharmaceutical life cycle products, and we were a customer of Dell EMC.

There was no problem with the stability. It was, as expected, very strong.

You can grow as much as you like. There is no limit. It's easy to scale.

We had about 1,000 users of the Unity XT.

We did not need to contact their technical support.

The initial setup for Unity XT was pretty straightforward. We knew exactly what we needed and our requirements were very easily applied to the box. With one day of hands-on training, my colleagues were able to manage things.

Maintenance required one person.

We used an integrator for the deployment. They had great knowledge of the product. We also did some additional integration with them in other parts of the storage, including backup and data domain devices, because we were very fond of the work they did.

The main factors to consider are space, availability, business continuity, performance, and IOPS. The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations.

It is a very complete platform. Dell EMC wrote a new OS for storage, but I haven't seen it yet.

We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition.

It is for a customer who does virtualization.

We use replication for disaster recovery (DR), making our DR process much easier.

Price and performance are its most valuable features.

It streamlines processes.

I haven't seen the roadmap for this solution.

It has met our overall performance expectations. The solution runs as we need it to, without any issues. It hasn't failed.

We haven't tried scaling yet.

The technical support is good.

We had performance issues with our previous product, which is why we started to search for a new solution when we did a reorganization. We decided on this solution because of the performance that we receive from the solution.

The initial setup is straightforward: Just connect, plug in everything, then do the configuration wizard.

We are integrators.

Our CAPEX was close to $42,000 and operating costs are below $1000.

We also evaluated HPE and Lenovo.

The product has met all our expectations.

Take a closer look at the price per gigabyte and the performance that you are getting with the solution.

We bought a couple of 450F and 650F to replace our ageing VNX family. The primary use case is for block storage, and VMware for our tier-2 applications.

Moving away from Java-based Unisphere to the HTML5 version of Unity is a huge improvement for our day-to-day management. We are still in the process of getting things in place, but at this stage, I can say the configuration is pretty straightforward and doesn't require additional training to learn the product.

Moving also from a hybrid to an all-flash array helped us to minimize footprints in our data centers. It's like two racks of VNX 8000 down to a quarter rack of Unity 650F.

• New HTML5 GUI: It's really fast and works well on your favorite browsers.
• Data reduction: We haven't seen the actual benefits, but with this feature, we are expecting to gain maximum efficiency.
• CloudIQ integration: This provides really useful data and analysis.

• Storage groups are no longer available in Unity so you will have some challenges if you managed quite a huge environment in provisioning perspective.
• Domain management is also gone in Unity. This is not an issue if you are managing less than two of this, but in our case, we have a number of this array around the globe.
• All models are limited up to two I/O modules per SP giving you fewer front-end ports compare to higher VNX models.
• Unisphere Central is not so useful as we expect. This will provide a centralized management of our arrays, but it ends up giving you only some numbers and figures for you to report to your management.

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.
