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."Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"It's just very easy for general block storage."
"The deduplication and compression rates are beyond impressive."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"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."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"We use it to implement all our VDI solutions."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"The most valuable feature is the fast cache with functionality rewrite."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"I have found Dell EMC Unity XT to be stable."
"I like the ease of configuration, the quick setup and the fact that it seems to be hardened. We haven't had any issues with them. In terms of simplicity of ownership, once they're running you don't have to touch them. They're also simple to manage. We came from the VNXe 3200s so it's very similar."
"Inline data reduction is pretty impressive."
"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."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"In the next release, I would like to see file-level encryption."
"The price should be lower."
"If they could make it cheaper, that would be something."
"Self-backup is the only feature lacking in this solution."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"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."
"Ordering is easy, but the processing site and working with those companies was difficult."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"Scalability of this solution could be improved."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"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."
