[Networker] Adequate server hardware to feed 3-4 LTO3 drives
2007-10-08 08:47:12
Hello,
What might be your concern regarding throughput or scsi id contention ? or
is it HBA performance ? We have been running atleast 4 drive\HBA over 2
Gb FC
( LTO2) without any issues for long time. Unless your backups are mostly
over the SAN, i doubt that you could utilize the full drive potential with
ethernet.
Which hardware ( servers) are out there which you would recommend & will
support 20+ HBA to allow one Drive per card ? which is what we have
running between Physical Tape Lib ( Adic i2K & Netapp VTL).
Thanks

Does a 4 GB switch exist? Perhaps a 4Gb switch might be more realistic?
I really wouldn't put 4-6 drives on one connection. I wouldn't put more
than two, perhaps even only one.
