"Its array houses our entire production environment."
"It has good stability for our company."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"The compression and deduplication features help to make the best use of the capacity."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"It worked flawlessly."
"The solution is very reliable."
"Virtualization of external storage, while adding cache and speed to the external storage."
"The most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"We are a 100% satisfied with the stability of the solution."
"The installation is nice and easy."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"I really value deduplication and compression to save space."
"It is very stable, even during multiple power failures."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"The replication feature provides another functionality to protect your data."
"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."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"Storage. There could be better storage."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Self-backup is the only feature lacking in this solution."
"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."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"The interface of this solution could be improved."
"The pricing needs to be more competitive."
"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"I would like to see an improvement in the handling of large amounts of rights."
"Cloud file sharing is an area that needs improvement."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"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."
"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 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."
"Poor connection to FC."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"If the VNX had embedded encryption, that would be great."
