Price / Quality ratio is good and since OE 5.03 code the array family reached a rather good maturity level

Pros and Cons

  • "The most valuable feature is the integration with vCenter."
  • "Support Responsiveness & time to fix bugs should be improved."

What is our primary use case?

We are running 3,000 VMs spread out over five such units.

How has it helped my organization?

The initial Unity x50 series, even all-flash, were quickly driving the CPU to near 100% on as little as 180TB, having data reduction on all volumes in place.

The XT came in support and sizes better on our infra, due to more CPU power. The system doesn't seem to have a module to offload datareduction, but in the end does a great job in getting the datareduction come round at higher capacity without oversubscribing the CPU (%). In the end the SDD media cost more then the array/storage processors. So basically you want to datareduce as much as the system can take.

What is most valuable?

Good in-built monitoring tools from the System|Performance section Tab, from CloudIQ you can reach out to vCenter as well. ESRS (Call Home) on the service delivery part is valuable.

Remote Code update support (interactive or not) is free of charge , as you wish, nonetheless you are free to do it yourself as update are cumulative and retained on each new codelevel.

What needs improvement?

The UEMCLI is not an object-oriented CLI and the more object-rich PowerCLI has been discontinued. Only people with bash experience possibly can operate it. Still nowadays, feeding object from one command into another is still a burden with such CLI. When adding a few disks to a cluster, the CLI is actually standing in the queue for one disk to be added to all, requiring multiple scans on each membering host, before proceeding with the second...and scanning all hosts once again.  One could add all disks at once and stand in the queue once for a rescan all.

There isn't a means to add volumegroups , nor hostgroups. A feature that any solution I worked with so far has. Its a burden to assure each host has the same LUN ID on each host in this manner. As of the june 2021 releae , code OE 5.1 it seems to offer the option to have hostgroups in the end !

The integration with vCenter comes with a sideeffect, in that it will take control of the vSphere scan process, moreover every esx host is scanned multiple times. It takes easiliy a few hours to add a few LUNS to a few hosts. Rather Painfull. Even when adding LUNs using the unisphere GUI , you can keep up with the pace of your script.

Support Responsiveness & time to fix bugs should be improved. Over the past 1,5 yrs we had occassional controller reboots and we went all the way from OE 4.5 over 5.02 to 5.03 and eliminated the  most common causes. We still face a stress triggered cache merge issue and though we provided the dumps and engineering acknowledged the bug, it has been told that addressing the bug requires substantial code rewritting and the problem will be fixed in the next major code release (OE 6.x) . We are now a year later, still no fix, but furtunately faced the considition once on one out of 5 arrays during that year. 

For how long have I used the solution?

I have been using Unity (XT) for 15 months.

What do I think about the stability of the solution?

OE 5.03 is a rather mature & stable code, without to say that it will addresse all. Some bugs are stress/load triggered and rather exceptional but might be easily recurring if the same conditions are remet.

What do I think about the scalability of the solution?

The XT scales better then its predecessor. 

How are customer service and technical support?

Not the most responsive support, we have a Service Account Manager and reporting in place now and keep the pressure to get answers. Very bad post bug/incident follow up.

How was the initial setup?

The system is easy to install and you might be able to do it on your own on the 2nd attempt.

What was our ROI?

Ease of use, Price Quality, vSphere Integration, CloudIQ (Performance data) , ESRS (Call Home) and though not used as such , Support for Block Devices, Cifs,NFS

What's my experience with pricing, setup cost, and licensing?

The setup is rather straighforward.

Which other solutions did I evaluate?

I have compared Unity x00/x50f versus Unity XT x80f. 

What other advice do I have?

Midrange solution for SMB up till Large Entreprises too if you spread the load on many units.

Which deployment model are you using for this solution?

On-premises

Good integration, an easy initial setup, and quite stable

Pros and Cons

  • "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."

What is our primary use case?

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

What is most valuable?

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

Integration is easy with this product.

What needs improvement?

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.

For how long have I used the solution?

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

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

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.

How are customer service and technical support?

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.

How was the initial setup?

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.

What's my experience with pricing, setup cost, and licensing?

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

What other advice do I have?

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.

High availability, stable, and good support

Pros and Cons

  • "The high availability of Dell EMC Unity XT has been the most important feature."
  • "The interface and configuration could improve."

What is our primary use case?

We use Dell EMC Unity XT as a storage solution for a virtual machine datastore.

How has it helped my organization?

Dell EMC Unity XThas helped our organization with the high availability. It has been working very well and the performance has been good with an old flash solution that we are using. It has improved the reliability and speed of virtual machines.

What is most valuable?

The high availability of Dell EMC Unity XT has been the most important feature.

What needs improvement?

The interface and configuration could improve.

For how long have I used the solution?

I have been using Dell EMC Unity XT for approximately six years.

What do I think about the stability of the solution?

The solution is stable.

What do I think about the scalability of the solution?

The solution does not fully scale because it's a scale-up solution, not a scale-out, but if you get the right target, you will be able to scale up to meet your needs. We are not planning to expand the storage of the solution at this time.

We have approximately 200 users using this solution.

How are customer service and support?

The first level support from Dell I was not happy with because as a technician I needed to get the second or third level support. However, the level one support was able to pass me over to the right technician and I received the solution pretty fast. The support overall was very good.

Which solution did I use previously and why did I switch?

We previously were using the Dell EMC VNX storage and before it, we used CX storage. It's is basically the same solution evolving during the time.

How was the initial setup?

The implementation is straightforward, the configuration tool two hours, and to deploy it took approximately three days. We did some configuration changes and considerations which took a lot of time to test.

The interface and how the configuration needs to be completed could be simplified.

What about the implementation team?

I did the implementation of this solution. The solution works well and does not need any maintenance or assistance unless it is broken.

What other advice do I have?

My advice to others is for them to make a good plan and to use that resource they have.

I rate Dell EMC Unity XT an eight out of ten.

Stable and problem free solution

Pros and Cons

  • "I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
  • "In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."

What is most valuable?

The most valuable feature that Unity had at that moment was the ability to communicate with the previous family, the Clariion. So, the migration and all the data transfer was really easy.

What needs improvement?

In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside.

For how long have I used the solution?

I have been dealing with Dell EMC Unity XT for something like 20 years.

The oldest implementation I have done for Unity was about six, seven years ago and it's been working pretty good. No problem so far.

What do I think about the stability of the solution?

I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward.

Which solution did I use previously and why did I switch?

We switched to Unity because of the price, but that was for the migration from IBM to Dell Clariion. And when replacing the Clariion to the Unity, it was an easy migration of the data.

How was the initial setup?

The initial setup was simple. The main problem is that you need an extra appliance outside of the disk - you need extra hardware.

What other advice do I have?

My advice would be the same thing as the Data Domain - it is important that there is good sizing at the beginning. It makes a difference.

On a scale of one to ten, I would give Dell EMC Unity XT a 10.
