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."Overall stability is very good. It is a very stable solution."
"The latency is good."
"The most valuable feature of this solution is reliability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"It has good, reliable, fast storage."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."
"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."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"The solution overall has high performance."
"I like how it separates the iSCSI drives from the standard shares. It has two different routes to it. I know most of the other solutions do this, but I just like the way that Dell EMC does it."
"For me, the most valuable feature is the ease of management."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"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."
"It is on the expensive side."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The tool's pricing is higher than competitors."
"There is room for improvement in the pricing of the product."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"The pre-sales technical support and technical engagement could be made better for this product."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"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."
