We performed a comparison between Dell XtremIO 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."Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"We are very happy with the data deduplication and compression ratio that we have on the platform."
"Data deduplication features make it easier to manage storage and forecast growth."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The performance is very good."
"The most valuable feature is its data reduction."
"Thin storage allocation"
"Ease of management, aside from the serious performance, is the best feature."
"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."
"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."
"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."
"The Metro clustering and solid-state performance, are the most valuable features of this solution."
"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."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"The price of this solution could be improved."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"Larger capacity and more storage ports would be the two things I'd like to see."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"I would like to see more scalability."
"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."
"Native data replication: To replicate data between XtremIO devices, you need to use EMC’s RecoverPoint appliances to move the data."
"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."
"It is very expensive to scale. You have to buy an additional system to extend from one disc, for instance. It is scalable, but extremely expensive to do so."
"The product could be improved by reducing the pricing and having better organization in their technical support team."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"Ease of use is key in the converged and hyper-converged world that requires administrators to have both hypervisor and storage skills."
"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."
