We're about to buy an external LTO-4 tape drive for our HP DL380g6 server, and since SCSI is on the way out, we'll buy a SAS drive, probably the HP StoreEver LTO-4 Ultrium 1760 SAS External Tape Drive (but feel free to recommend something else).
Now we haven't got any SAS ports available, so also need to buy a controller card. Would the following controllers work (listed from cheap to expensive)? Are these cards reliable? Or would you recommend other cards?
Lycom PE-123e HP Smart Array P212/Z HP SC44Ge Host Bus Adapter HP SC08Ge Host Bus Adapter
If the only thing it has to control is a single external tape drive is there any reason to go for more expensive models?
Which cable do I need?
