Fibre doesn't have the distance limitation SCSI has. Fibre drives allow for
sharing/moving of tape devices from host to host without the need to re-cable.
If your using more sophisticated backup techniquies there are other advantages.
Speeds should approach 35MB per sec. I thought I saw 45 MB per sec.

The big advantage of Fibre that I have found (at least in a Windows
environment) is that you don't have to reboot the server when you reboot the
Jukebox. It will rediscover the drives after the Fibre channel tapes come
back up.

I tested SCSI and Fiber connected tape drive and din't find any differnces
in backup speed. New SCSI adapters support 320MB translating rate. LTO2 has
20-25 Mb backup speed (as usual less). So IMHO no differences, only in cost.
Besides, the buttleneck in backup, IMHO, is network, NIC (if you take backup
via network).

Subject: [Networker] LTO2 tape drives - fibre vs. scsi
Im getting some new HP LTO2 tape drives for my library and i have 2 extra
1GB brocade switches.
Is there a big advantage to getting fibre attached tape drives compared to
scsi?
The legato 7 server is on a mid range sun server running solaris 8.
thanks!
