[gpfsug-discuss] Strategies - servers with local SAS disks

[Oesterlin, Robert]

Looking for feedback/strategies in setting up several GPFS servers with local SAS. They would all be part of the same file system. The systems are all similar in configuration - 70 4TB drives.

Options I’m considering:

- Create RAID arrays of the disks on each server (worried about the RAID rebuild time when a drive fails with 4, 6, 8TB drives)
- No RAID with 2 replicas, single drive per NSD. When a drive fails, recreate the NSD – but then I need to fix up the data replication via restripe
- FPO – with multiple failure groups -  letting the system manage replica placement and then have GPFS due the restripe on disk failure automatically

Comments or other ideas welcome.
