We performed a comparison between Dell Unity XT and VIOLIN QV2020 based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The initial setup was really straight forward."
"The stability and performance are the best things about the solution."
"It gives us capacity planning."
"It worked flawlessly."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"It's extremely stable and has good performance."
"It simplifies the overall management. We don't have to worry about storage anymore."
"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."
"Inline data reduction is pretty impressive."
"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."
"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"VIOLIN QV2020 is the latest in terms of performance. It has high-speed data access and processing capabilities, distinguishing it as a leader in its storage solutions category."
"It’s simple to use hardware to fix performance issues. Our issue is poor coding/queries. This greatly speeded things up. It’s too costly to track down poor programming in applications. The price of a developer’s time to scan through all the coding is high compared to buying Violin."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"Most of our upgrades have not been as smooth as they should have been."
"It needs to improve its price."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"The technical support is okay, but could be improved."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"The scalability of the solution is not as good as it probably could be."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"They should update to the cloud."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
"VIMM replacement is poorly designed. You have to slide out an entire drawer, remove the cover and then pop out the failed VIMM. I would like to see a front replacement just like with hard disks. This leaves room for error; for example, when you slide it out from the rack, you are moving cables along the cable management arm. This leaves the possibility of accidentally unplugging a cable from the array if it is not seated properly. Also, you might pinch the cables when sliding it back into the server rack."
