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

[Chris Hunter]

Smells of troll bait but I'll bite.

"Declustered RAID" certainly has benefits for recovery of failed disks 
but I don't think it claims performance benefits over traditional RAID.
GNR certainly has a large memory footprint. Object RAID is a close 
cousin that has flexbile expansion capability, depending on product 
packaging GNR could likely match these features.
Argonne labs (Illinois USA) has done a lot with both GNR and RAID GPFS, 
I would be interested in their experiences.
