IO Performance.
IO Performance.
We have moved GPFS's metadata to the SSD disks, the incremental backup is 6-8 times faster (we have over 120,000,000 files and backup takes "only" 30 hours now).
Our next step is to migrate TSM database to SSD array and we hope that allows us to once again reduce backup time.
IO intensive tasks.

Yes
I/O performance is good enough, but to achieve big capacity TB/s you need better controllers and many more SSD drives (we have over 1 PB of storage and only 15 TB of SSD disks).
Good.
Technical Support:Good.
We needed much more I/O, and the size and the GB/s performance was enough.
It wasn't complex.
We implemented it in-house.
We are a non-profit organisation, and we must deliver the best performance solution for our users.
The power consumption is very low, and the size is small (2U) and these are the only costs at this time.
We knew that we needed SSD array.
Buy as much support as you can afford.
