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."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 predictive performance analytics are good."
"The product cheaper compared to other solutions concerning the technology that they are using."
"The stability is perfect. The reliability is 100% and the latency is always lower than 1 millisecond."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Good performance for VM environments"
"It is very stable, even during multiple power failures."
"I really value deduplication and compression to save space."
"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."
"Integration with VMware"
"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."
"I would like to see support for NVMe, end-to-end."
"I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"The system has dual controllers but does not have a high level of resiliency built-in."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"I would like to have support available in Spanish."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"The exterior display needs to be improved."
"The CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"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."
"Poor connection to FC."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
