[Beowulf] Large raid rebuild times

[james bardin]

Hello,

Has anyone here seen any numbers, or tested themselves, the rebuild
times for large raid arrays (raid 6 specifically)?
I can't seem to find anything concrete to go by, and I haven't had to
rebuild anything larger than a few TB. What happens when you loose a
2TB drive in a 20TB array for instance? Do any hardware raid solutions
help. I don't think ZFS is an option right now, so I'm looking at
Linux and/or hardware raid.


Thanks
