I'm looking at making the same decision here - to buy GPFS or to roll our
own Lustre configuration. I'm in the process of setting up test systems,
and so far the main difference seems to be in the that in GPFS each server
sees the full filesystem, and so you can run other applications (e.g
backup) on a GPFS server whereas the Luste OSS (object storage servers)
see only a portion of the storage (the filesystem is striped across the
OSSes), so you need a Lustre client to mount the full filesystem for
things like backup.
However I have very little practical experience of either and would also
be interested in any comments.
