With an SGI IS16000 array which supports up to 1,200 drives, filesystems
with large numbers of drives isn't difficult. Most configurations
using the IS16000 have 8+2 RAID6 luns. I've seen sustained 15 GB/s to
a single filesystem on one of the arrays with a 600 drive configuration.
The scalability of XFS is impressive.
