Hi *,
Can anyone share with me, a good rule-of-thumb for the maximum number of
LTO
drives that should be attached to a single Ultra-II SCSI bus? Using the
theoretical max transfer rates of 15 MB/s for the drives and 80 MB/s for
the
SCSI, I shoould be able to put 5 drives on one bus and still have room to
spare (theoretically). What is the generally accepted maximum number, in
the real world?
TIA
David Taylor
