Good afternoon,
HPA mentioned that you guys might be able to give us some suggestions on
implementing xfs on the kernel.org machines.
Specifically I know was asked:
<sandeen> what sort of storage is behind it?
<sandeen> local disk, or raid, or ?
<sandeen> knowing what's behind it (ide/scsi? geometry?
battery-backed cache?) might help w/ the recommendations
The storage that will be used is 300gb u320 10Krpm scsi drives, in total
21 drives (No obvious geometry is available but the model of the drives
is a Compaq BD300884C2). These will be connected to the system via an
HP Smart Array 6400 w/ 192mb of cache and a bbu (so we have
battery-backed cache on the controller).
Our current intention is to run hardware raid 6 across 3 subsets of the
drives (due to controller limitations) which will give us three raid 6
arrays of 7 drives each (total of 21 drives than). Beyond that - I'm
open to suggestions. I had thought of doing software raid0 across the
resulting three arrays and running xfs over that, though if there is a
compelling reason to do things a different way I'm open to hearing about
it.
Anyway any and all suggestions are welcome.
