We performed a comparison between Hitachi Universal Storage VM [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."It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"The stability of Pure Storage is very very good."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"The deduplication and compression rates are beyond impressive."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Because of the encryption, we have different storage and the encryption can go over both."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"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."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"I really value deduplication and compression to save space."
"Integration with VMware"
"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."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"Multi-tiering, positively affects the efficiency of the storage space."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"In the next release I would like to see integration into other third-party player providers like Google."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Self-backup is the only feature lacking in this solution."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"The exterior display needs to be improved."
"Poor connection to FC."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"The CLI could be better documented, like with VMAX."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
