We performed a comparison between VIOLIN QV2020 [EOL] and VNX [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 its ease of use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Overall stability is very good. It is a very stable solution."
"The high availability of the product is the most valuable feature."
"It has good, reliable, fast storage."
"The initial setup was extremely simple and straightforward."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"I really value deduplication and compression to save space."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"It is very stable, even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"Integration with VMware"
"The replication feature provides another functionality to protect your data."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The tool's pricing is higher than competitors."
"The software layer has to improve."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"In terms of what needs improvement, the dashboard and management could be simplified."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Poor connection to FC."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The CLI could be better documented, like with VMAX."
