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 most valuable feature of this solution is reliability."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The high availability of the product is the most valuable feature."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"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."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"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."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"It has good performance."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's pricing is higher than competitors."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The tool's portfolio is minimal. It is expensive."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"They could add more support for file storage and different types of storage."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"A customer had to buy VMX because Unity didn't have WORM."
"The price of this product can be more cost-effective."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"Thick provisioning of LUNs."
"This solution would be improved with the addition of flexible raid volumes."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."
"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."
