I'm reviewing quotes for VTLs. I currently have one from Cybernetics and
one from LaserVault. One quoted for SAS, the other for fiber. Our current
TS3100 physical tape library is connected via 57B3 3GB SAS cards. Our
internal DASD is connected to two 57D8 8GB SAS RAID controllers.
Unfortunately when our business partner initially set up this box they
optimized the RAID array for size instead of for performance, so all DASD
I/O is going through one RAID controller, and the other will only take over
if the active controller fails. With that in mind, would there be any
benefit from connecting a VTL via fiber, or would our internal DASD be a
bottleneck? All of the above pertains to an 8286-41A.
