Currently, we are also using Nutanix, Vison, ScaleIO, and Huawei as an STS solution. The problem is that we want to use one solution in the future and not five.

I have to compare all of these and decide which one is the best for the future.

We still use NAS and NFS (mainly NFS), which we used prior to Spectrum Scale.

We added Spectrum Scale because of its scalability. There are just large amounts of data, especially with Ab Initio, NFS would not cut it.

We were previously using the JFS2. We switched because it was the recommended solution to our SAS problems, and it worked.

I would rate IBM Spectrum Scale at a six out of ten.

We were not using anything before this solution.
