Dell EMC Unity XT reviews

I am handling the maintenance of Dell Unity XT, particularly for a leading telecommunication company in Sri Lanka. They use Dell Unity XT as one of their storage areas.

Dell Unity XT is a stable product, and it rarely encounters hardware issues. My customers, including a leading telecommunication company, benefit from several storage areas. Unity 400 is a part of their storage solutions.

I believe if Dell can integrate AI to predict potential failures, especially in hardware like hard disks, that would be very useful for proper maintenance.

I have been using Dell Unity XT for more than one year.

I would rate the overall stability of Dell Unity XT an eight out of ten. It is quite stable.

Dell Unity XT is quite scalable and can be scaled up to the petabyte level. I rate the scalability nine out of ten.

The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten.

Neutral

It wasn't my personal choice to choose Dell, but we have contracts with Dell and occasionally with HPE.

There are three engineers, including myself, who are part of the maintenance team. Not all of us engage full time.

Overall, I rate Dell Unity XT an eight out of ten. I am satisfied with how Dell Unity XT integrates with other tools, as I didn't face any issues. I would recommend Dell Unity XT to other companies.

On-premises

This solution is used for primary storage. We have a single installment with many units throughout our on-premises environment. We only have one XT unit and it is used for one of our core environments. It provides critical services such as DHCP and DNS.

This solution helped us reduce our physical footprint and power consumption. 

The inline deduplication and data reduction capabilities have been the most valuable.

I have been using this solution for five years. 

This is a stable solution.

Scalability of this solution could be improved. 

I would rate support for this solution a six out of ten. A few years ago, I would have rated it an eight or nine out of ten. The biggest challenge is responsiveness and getting to speak to someone who really understands our challenges. 

Neutral

We previously used VNX. We switched solutions to have an updated platform and integrated NAS services.

The initial setup was very straightforward. It is a plug-and-play deployment. It took half an hour to deploy and required two people. It requires routine updates for maintenance. 

We have experienced a return on investment using this solution. 

This solution offers great pricing. 

We evaluated NetApp before choosing Dell. We are more familiar with Dell's products which is why we decided to use this solution. 

I would rate this solution an eight out of ten. 

On-premises

We use the solution for site recovery manager, DR, and endpoint penetration. Dell Unity XT is integrated with vCenter. It has automation and is configured automatically in Vcenter.

It would be great if the solution could integrate an NVMe disk.

I have been using Dell Unity XT for two years.

I rate the solution ten out of ten for stability.

I rate the solution’s scalability ten out of ten.

The solution's technical support was fast.

Positive

It is very easy to set up and configure the solution.

It is not hard to manage Dell Unity XT. Dell Unity XT works fine and has never failed since its implementation in our infrastructure.

Overall, I rate the solution ten out of ten.

My clients use it from a virtual environment. So, there is a NAS application as well.

It is an on-prem virtualization solution.

In my experience, the application configuration is a standout feature. It allows users and even admin nodes to be configured more smoothly. The process, especially after zoning, has become more streamlined with enhancements in bin management, cleaning, and initiatives.

The ability to have flash to adapt to your environment. It's one of the best solutions you can actually use for the database.

Dell Unity XT's integration capabilities are good, like VMware features and other features that are already added. It's quite good.

It is easy to use. The interface is quite user-friendly, and the integration is not too difficult.

The only challenge I've ever had was with a Drive firmware upgrade.

However, when I did an on-prem performance [assessment], it didn't pose much of a problem.

I have been using it for six years.

I would rate the stability a nine out of ten.

I would rate the scalability a ten out of ten.

I've done upgrades a couple of times. It wasn't too hard to upgrade. A few times, it involved adding capacity depending on how the size of the collections began. And boom, we're good to go.

Within the last three months, I did an upgrade on Unity. It was quite simple. We downloaded the firmware, and then there was a bit of setup. And just a few steps, and we were ready to go.

Our clients are usually enterprise businesses. 

The only time I've ever had a challenge was when the problem had gone beyond the initial support. And when we moved on to the next person who took over, it was really about them fully understanding what we had been troubleshooting.  

Positive

The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy.

It's quite easy. Once you have the application that needs to set up the connection in utility, we are good to go.

I have not had any cloud training in Unity. But the first time I had to deploy one by myself,  it was one of the easiest things I could ever do.

The deployment takes a few minutes. Because if you have your IPs prepared and your router is done, the deployment usually just takes a few minutes.  

I would definitely recommend using it because of its integration part and scalability. 

I would rate it a nine out of ten. 

On-premises

We are using it mostly for VMware and Wintel. It is also for applications, like SQL, which need to be used on multiple different operating system, such as Windows, Linux, and sometimes Citrix. We use it with virtualized infrastructure.

We use QoS and snapshots features, which I like.

Unity provides a complete storage solution for VMware on a Wintel Windows box for various applications, such as SQL or Patron Databases. It is seamless, and it sits there providing all the storage and connectivity, so we can forget about it. Unity takes care of itself, solving all the basic needs of a robust infrastructure.

It is easy to deploy. That is the best feature that I like, because I used to fly into locations to install a Unity. We used to have an expense of $5,000 on the product. Now, I just send whomever is onsite over there locally with the initialization information in a text file. Then, they can put it in a USB drive, come back, and it's deployed. Afterwards, I can remotely access it, saving us $5,000 every time. It is not very expensive, so the value added is you get big bang for your buck.

If I can connect to my Unity through my iPad or my cellphone to check everything is okay and view the information via a dashboard. 

I would like to have secure mobile connectivity going forward. This would help me be more proactive.

It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about.

We are so virtual that we have two of us managing the whole infrastructure. Everything is taken care of and highly available. Nothing is vulnerable at all. Everything is good. There have been no issues at all, so far.

We have 30 to 40 Unities out there in the field. We don't even scratch the full capabilities of the Unity. We are at about 20 to 30 percent utilization. It is just provisioned so well that we are sitting at 90 percent performance level. We have it well-provisioned so we don't need to worry about performance for the next five years.

It is quite scalable. If you want to add on, you can add on easily. We have a 25-slot enclosure and are probably at 15 right now. If we purchase a big company, need to scale up, we can easily scale up. 

If there's any issues with a hard drive or any other hardware components, Dell EMC is contacted, then they will call us back to schedule to get into the data center to replace something. This is all virtual. Support is not a problem, because it's automatically taken care of. Only thing we have to do is to give them access to the data center to go do what they need to do to fix it proactively.

The local account team and system engineer are the best part of working with Dell EMC.

Everything is becoming virtual. Then, cloud transformation is being considered right now. Everybody is going over there. We want to evaluate everything, and if the cloud solution is good for us, we'll go there. Everything will be in the cloud.

We use it for block storage for our entire VMware environment, which runs Windows, Exchange, and SQL Server. The Unity also provides block storage for bare metal Windows Server that run our backup software. We also use file storage primarily to store images.

I use it with three projects that I directly work with. Each of those projects has 80 to 100 virtual servers. We have sysadmins who are dedicated to each project and do all the admin tasks, like checking VMs, servers, storage, etc. There is a larger team of five or six systems engineers who backstop all three of those projects. We focus on architecting and configuring any servers, storage, and networking. We may also be called in to resolve performance concerns.

Unity/Unity XT is significantly more user friendly than VNX.

We can do both block and file storage on one unit. For our projects, we use both of those functions. This is a key feature for us, along with very solid, predictable performance.

We use VMware in a number of projects but there isn't very good visualization of the storage from VMware or vice versa. I'm hopeful this improves in the follow on product, PowerStore.

I have been using this solution for the past seven years, previously at Dell and three years with my current company.

Stability has been very good, even the older models of Unity are quite good. The non-XTs and the XTs have been absolutely stable. We have had a couple of small hardware glitches, e.g., I have had to replace an LCC. That is literally it over the last three years.

This is a newer model for us. Out of the three projects that I have worked on, two of them are using the older model and the XT is primarily in another project. We have tons of scalability in it. We have a whole rack dedicated to Unity, and it is pretty much empty. We have probably close to a petabyte of storage in there, and it is still pretty much empty. Scalability looks really good.

Where we would run into a scalability problem, we are going to do a lot of image storage, and that doesn't compress well. So, flash drives wouldn't really help us. We need a big, scalable object storage system. That is where Isilon comes in. We have about three and a half petabytes of Isilon at each of that project's sites.

The technical support has been really great. I have never had a problem that they were not able to get to the bottom of pretty quickly.

Positive

We do have Dell EMC SC storage, which is very simple and straightforward, which is good for our small remote locations. However, it doesn't have the performance or features that the XT would. As far as block storage, Unity XT is probably the best bank for the buck for us because we can get block and file storage in one package. We don't have to buy a separate Isilon for object storage.

Including VNX, SC, and Unity/Unity XT, Dell EMC has provided all the storage solutions at the company for the last 20 years. 

The initial setup was super easy for the most part. 

I will note one issue. This might be on the sales team, but we had a need for encryption that I am sure we mentioned. However, the Unity that showed up at our data center did not have the licenses for encryption at rest. I would love to see Data At Rest Encryption (D@RE) be just the default since I can't imagine anyone wouldn't want it at this point. It would have made life easier for me. I definitely had to completely wipe out an array three days after we set it up, because it didn't have encryption, then redo it with a new license.

Vendor did initial install. I reinitialized it and did the final install.

There are cost savings from having a single solution that does both file and block storage.

Pricing could always be better. Dell likes to charge a premium price for these products.

I would say the major complaint with pricing is that Dell EMC comes to us and gives us a an initially high price. We usually need to go back and forth to negotiate the price to a more reasonable level. We are not going to just say, 'Yes,' because we are out of time." 

I don't know if the discounting structure needs to be better or more consistent. 

Having worked at Dell EMC previously, I know they have discount floors, etc. I just wish they would note, "This company gets a 55% discount." Just be consistent with it. Company-wide, we buy all our storage from them. They should be able to give us something a little more structured.

In one project, we needed more scalability that the Unity can provide so we are using Dell EMC Isilon for it. In that case, I needed multiple PB of object storage.

Otherwise, we have not looked at much else. In the future, however, we will probably transition to Dell PowerStore.

I would rate it as nine out of 10. It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is wonderful for my piece of mind.

On-premises

We use Unity solutions for our data center operations as a primary storage environment.

We were able to retire all our VNX systems and reduce the footprint in the data center. The Unity systems can scale up quickly, so we use less space in the data center if we employ more Unity systems than the old VNX systems.

Unity is scalable and you can configure it quickly. 

One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX. It takes a little more work when we are incorporating a third-party environment. 

I've been at my current job for almost five years, and we have been using Unity that whole time.

I believe Unity is stable. However, we haven't used it for long, so I can't really know how stable it is until we have enough time to work with it.

Scalability is one of Unity's biggest advantages. It looks like we're going to need to do a lot of expansion because any capacity we purchase gets consumed pretty fast. We'll have to increase our footprint on Unity.

I rate Dell EMC support 10 out of 10. They respond rapidly and do a good job. When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good.

Positive

My company was using EMC Symmetrix. They moved from Symmetrix to Dell EMC VNX and then Unity. They have not done any other evaluations of other vendors aside from EMC.

Implementing Unity was straightforward. We were able to move through the process of setting up the systems based on the procedure the vendor provided without any problems. Once we got started, I think it was just a couple of days. 

The company purchased a support contract, so we worked with Dell EMC to deploy the system.

We just deployed these new Unity systems a couple of months ago, so we haven't had an opportunity to assess the cost savings yet. As we continue moving ahead, we'll be able to do that. The company is scaling up Unity, so if they are willing to scale up quickly, they like the product, and there is something advantageous to the systems. Whether in terms of money or performance, they seem to be getting some value from the systems.

I'll rate Dell EMC Unity nine out of 10. It's a great, scalable product that performs well. Out of many options, it would be my first choice.

On-premises

We use it for post to all our data stores or virtual environment.

We have had no performance issues. 

As far as benefits, Dell EMC Unity XT gives us fast access orders for everybody in accounting, and it's working. It is all-flash and is in extreme hyper-performance mode. 

When there have been critical updates, we will get phone calls from Dell EMC saying, "We need to update this, and because our contract support level is here, we can do this for you." They will bug you to death until you have updated it, which is good because we are overwhelmed.

It's all-flash.

The solution is so easy to manage that I forget it is there.

Their support is now a lot better, so that is good. They are very helpful when we called in and say, "This is the project that we want to do. Which box should we go about buying? They will send us the information and go through it with us."

We have had issues with the capacity and some misunderstandings on how much compression that we should be able to see out-of-the-box. When we were originally sold the box, it was before the merger. The salesman promised us at least a 50 percent compression on the box, so we ordered it with 2TBs of storage. That was a mistake, because now we are locked into smaller drivess. When it comes down to it, we are running out of space. 

We realized that were barley getting a 12 percent compression offset, not the 50 percent, and this came about the time of the merger. All of this was happening and a lot of people in the company did not return emails at the time. I guess it's because they were no longer with the company or they knew they wouldn't be, that's just speculation. However, it took us several months and almost ruined the our reputation during that time period. They did make right on it and sent us several drives to double the storage on our devises for free, so they made it right towards the end, but it took a while.

The iSCSI and the VMware integation using vSphere could be less confusing. 

Three to five years.

The box has been on 24/7/365 with the exception of one day when we had to change out the batteries in our battery backup. We realized our network cord was not working in it. 

When I left to come the conference, I looked, and uptime on the battery said "527 days".

You only have so many days in the storage. When you buy storage, buy more than you think you'll need, because it will come back and bite you. Because now, if we expand anymore, we will have to buy a box to piggyback on this storage. Hindsight is 20/20, but all-flash is expensive.

Technical support is much better now. They are  responsive, and it is easy to get to the right person. They will blow up your inbox and voicemail if you have a critical update that needs to be applied to either the drives or the box itself, which is great.

Previously, all our servers were running one instance of Windows, and running as a particular application. Email servers were on a server unto themselves. We had a mess. We had so much hardware. 

Because of Dell EMC Unity, I was able to turn off the server that I had been managing for ten years for email. This makes the server room a little quieter now!

We bought the box of all the licensing that we needed and not run into anything where we would need any additional licenses from Dell EMC Unity.

VMware is a different story, but as far as Unity goes, it's not been an issue.

Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government. So, we are lucky there. We have that working relationship with the folks at Dell EMC, and sometimes I even get to run into the rep or specialist at events, which is great. I don't get that with a reseller.

We also looked at iXsystems. We just purchased one of their boxes for storage. I've known iXsystems for a number of years, and they gave us a great price on an absolutely insane amount of storage because all we needed was a box set in a bunker for local backups. The Unity was just outrageously expensive for our needs, so we went with iXsystems. I've managed an iX box in the past. Those guys will bend over backwards to help you as well. So, that's why I chose to go with them.

Spec it out with bigger drives than you think you will need, because when you do expand, you're going to wish you had done that. If you buy bigger drives than what you currently have in a RAID, now you have to have a separate data storage. You can't have one continuous data store. For some people, that might be okay, but we really didn't want that but we were forced into having that.

We do integrate with vSphere. We tried Hyper-V and immediately regretted that decision and went back to vSphere. Right now, that is the only utilization and there are costs involved with the VMware integraton.

Most important criteria when selecting a vendor:

• Reliability
• The willingness to make it right when something goes wrong.
