We are setting up a new storage system for our company and I wan't to know if i'm running the best configuration possible;
The mission is to set-up a storage subsystem for our backup server, we have more then 400 backup jobs running at night from 200 servers.
Configured for Sequential Read
I'm using RAID 6 with NO spares
Using 512 KB for segment size
Using a combination of 2 MB / 4 MB stripe sizes for large data transfers
Enabled cache read-ahead
We are using a IBM DS3512 with DUAL controllers and it is attached to our server with two 6GB/s HBA controllers.
