We use NFS mounted, 8 disk 3ware IDE Raid

We are using a 3ware IDE Raid card with 8 IDE disks that we NFS mount
from the TSM server. The only part that goes to tape is copy storage
pools. Haven't had any problems with this setup.

Hi,

We are getting TSM 5.1 server, and want to run it on a linux box. Our
library will probably be the OVerland Storage Neo 4100 with LTO-2 drives.

We also want to have some spool space, and SCSI is the first thought. But
since IDE is getting cheaper and faster, I'm wondering if anyone has tried
out IDE as spool disks between the PC and the tape library. We could go
with either software or hardware RAID 0 (striping), which would further
increase the IDE performance. We also plan on upgrading our network to
Gigabit in a few months, so we don't want the spool disks to be the
bottleneck.

But since SCSI still outperforms IDE in relation to concurrent
operations, which the spool disks will most likely be doing (I.E.
writting from network, reading to tape), then maybe IDE is a bad idea.

Any thoughts?

Thanks in advance,

Alex
