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."The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"It has good, reliable, fast storage."
"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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The initial setup was extremely simple and straightforward."
"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."
"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."
"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"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."
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy."
"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’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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I'd like to see the product implement active replication for vehicles such as VMware."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"In the future, I would like to see integration with enterprise backup systems."
"We need better data deduplication."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"It needs more functionality and the ability to move across more landscapes."
"They can certainly improve in terms of monitoring."
"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."
