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Storage."We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"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."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The most valuable feature is its upgradeability."
"This solution has improved our organization. In the past, we had reports that were taking up to two hours and after switching to SSD storage the overall processing power dropped to half an hour. The end users saw an immediate performance gain."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The stability of Pure Storage is very very good."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"It is easy to manage. A lot of the system manages itself."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"The solution is so easy to manage that I forget it is there."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"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."
"Dell EMC Unity XT has good integration with VMware."
"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."
"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."
"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."
"Pricing could be better in comparison to other solutions."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"The technical support is okay, but could be improved."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"Storage. There could be better storage."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"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."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"Its replication technology could be better."
"The price of Dell Unity XT could improve."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."
"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."
"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."
"I set up Wi-Fi for storage, and since then, we haven't experienced any interruptions in service."
