Dell EMC Unity XT Pros and Cons
Dell EMC Unity XT Pros
We currently have two Dell EMC Unities going. One of them at our primary on-premise DR site. They communicate with each other. If we ever have to failover, it is right there and ready.
It is easy to manage. Managing it, I get alerts if there are any type of issues. I had a hard drive go bad, which had never caused any issues. Dell EMC contacted me, and said, "We are a shipping a new one out." My response was, "Why?" He told me that hard drive was bad. So, I went and looked, and it was. This was almost immediate. I never even knew anything had happened.View full review »
The solution is so easy to manage that I forget it is there.View full review »
I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid.
The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all.
We just recently started using the Dynamic Pools, so while it's scalable, we actually find it valuable that we can just pop in one or two drives when we need to, instead of having to add a whole RAID set. That has actually been very handy for us.View full review »
It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it.View full review »
I like the integration into VirtualCenter. I used to have to add LUNs manually, then scan them in and format them. It does that all for you, all in one, immediate deployment of LUNs.
It does great deduplication. From a storage perspective, we save money being able to dedupe right on the diskView full review »
We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface.View full review »
We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform.View full review »
It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy.View full review »
Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure.View full review »
Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage.View full review »
Dell EMC Unity XT Cons
We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s.View full review »
It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint.
It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports.View full review »
The iSCSI and the VMware integation using vSphere could be less confusing.View full review »
What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps.View full review »
I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving.
Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed.View full review »
We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug.View full review »
Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have.View full review »
My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be.
More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial.View full review »
Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product.View full review »
The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed. If it's on, it's on. So we have to be a little more WAN-sensitive, in some applications, which means we can't put it everywhere. That's the biggest issue for us, by far.View full review »
