[gpfsug-discuss] Disabling individual Storage Pools by themselves?

[Simon Thompson (Research Computing - IT Services)]

Do you mean in GNR compared to using (san/IB) based hardware RAIDs?

If so, then GNR isn’t a scale-out solution - you buy a “unit” and can add another “unit” to the namespace, but I can’t add another 30TB of storage (say a researcher with a grant), where as with SAN based RAID controllers, I can go off and buy another storage shelf.

What do you see as the pros and cons of using GPFS Native Raid and configuring your disk arrays as JBODs instead of using RAID in a box.
