We performed a comparison between Dell Unity XT and VIOLIN QV2020 [EOL] 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."Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The latency is good."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"Overall stability is very good. It is a very stable solution."
"The initial setup was extremely simple and straightforward."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"Dell EMC Unity XT has good integration with VMware."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"The NAS is also extremely easy to set up."
"We've never had an issue with storage."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"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."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"The price of Dell Unity XT could improve."
"Issues with slow responses from the support team."
"This solution would be improved with the addition of flexible raid volumes."
"The VNX reporting is much more granular, versus the Unity reporting."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"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."
