Ok, I decided to build a new system. At the momenten I'm thinking about a server with space for 12 SATA drives and a 3Ware 9550SX SATA RAID controller with 12 ports. The controller should be fast enought (380MB/sec RAID 5 writes) and is able to manage multiple logical RAID units. I need 6-8 of these ports for a RAID 5 to mirror the disks of the main server with drbd over GE (shouldn't be much traffic during the night when bacula runs). What about the RAID layout for bacula? What would be a good way to go with 4 SATA disks? 2x 80GB RAID1 for system + database? Separate db disk(s)? 2x 200GB RAID0 for spooling? I read in the archives that disk io is the bottlenck in most setups. Thus I'm a bit concerned about the right disk/RAID setup to get decent speed with the LTO3 tape drive.
