Eric Burgueño - PeerSpot reviewer
Simplified data management, tremendously reducing our users’ cognitive overhead
The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.
Paweł Jabłoński - PeerSpot reviewer
Used for VMs with replication a feature, but need upgraded SSDs
We use this solution. I configured and updated it. Of course, I was also a user of applications that store data on that storage. We already have an SSD solution. So, rather than planning to go with an SSD solution, we are focusing on expanding it. If a company wants to deploy something new, it should choose a product with SSD, and NVMe disks. Overall, I rate the solution a six out of ten.

Isilon is Scale-out storage, while NetApp is Active-Standby storage. Regarding the performance issue based on the field engineer’s experience, Isilon is better than NetApp in case of a huge amount of io, while NetApp is better than Isilon in case of a medium amount of IO.
