Featured Reviews

Paul Pearson - PeerSpot reviewer
Works well, is easy to implement, and has upgrade analysis capabilities
We love the product. Pure Storage works really well. The CAT tool and also the ability to upgrade the unit's place grades are great. It allows for in-place control or upgrades. It's a very simple implementation. They have a good tool to analyze upgrades. The stability is good. Technical support has been excellent.
Tejas Patil - PeerSpot reviewer
It's easy for users to access and saves us a significant amount of money
We have massive storage needs and currently have 20 terabytes of storage Nutanix. We are storing around 10 or 11 terabytes of data on NUS. The cost would be huge if we wanted to add another NAS. A separate NAS would require us to buy more hardware and add switches. Nutanix allows us to add more storage inside the same cluster. It has significantly reduced our storage nodes by about 50 percent. It has been effective for us in terms of operations, management, and control.
Alan Powers - PeerSpot reviewer
Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.
