How many clients with how many data to backup at night? How many HBA's / server? Is the data migrated to tape?
I never used/installed SAnergy, but: - SAN is 2g/s, LAN 1g/s, allmost the same speed - extra sanergy overhead (maintanence, more that can go wrong, extra license, ...) - cost of HBA vs cost of gigabit NIC - cost of SAN switch vs cost of network switch (you can even use a crosscable between the NIC's if you want: reliable + sheap) Also, if you backup over the SAN to tape or with SANergy, the data has still to pass to the TSM client, so i'ts passing the SAN twice. I don't think serverless backup is an option. I should go for LAN based backups. Stef
