I hae 20 identical boxes (2x 4-core cpus, 64G ram, 16x1TB SATA drives on

running linux 2.6.30
on 3 of the 20 I seem to have a max write speed of ~5MB/sec (as opposed to
100 MB/sec)
any pointers on how I can identify what is different about these three
boxes?
Do you have cache OFF on the 3 slow boxes ?
yep, that's what it was. rackable couldn't ship us boxes that were all
configured the same :-(
sorry for the noise.
is there a way (other than the closed source binaries) to monitor the
status of the array?
