We want to change our tape backup system and acquire a LTO8 tape drive.
Something that I cannot find the answer easily is what are the pro&con of the connectivty by Fiber channel or SAS.
For the moment I have find that :
- SAS 6Gb max // Direct connection less latency // Need SAS card on the server (or hypervisor)
- Fiber 10Gb max // can be shared by several Servers // A virtual server can be used
Our network for internal server is 10Gb so It's tempting to take the fiber option.
Do I forget something ?
Edit : Our Configuration is a 10 Gb Network dedicated (No VLAN tags) Admin Lan mixed in Rj45 and FC (which means only NAS servers // Replication server // Backup server // switches).
So the tape drive will be connected directly to a Switch//Server not a SAN.
