Hi Sam! What you are referring to is called daisy chaining which can only be done with SCSI. Fiber channel requires a point-to-point connection, so I'm afraid your reseller is right... The other solution is to create 3 point-to-point connections and thus you have to have 3 FC ports on your server. If I remember this correctly one FC adapter has two ports, so you will need two adapters in your host. My guess is that that's cheaper than buying a switch.

I have installed an IBM 3584-L32 Library with 3 FC LTO2 drives. I assumed that since the drives are FC-AL, I could attach them to a single FC HBA in my TSM Server, but my reseller say I need a switch, and the IBM Redbook "The IBM LTO Ultrium Tape Libraries Guide" (SG24-5946) states: The device can be attached directly to SAN switches or FC-AL hubs. Ignoring the questions of availabilty and performance, why can't I simple connect the first drive to my server, the second to the first, and the third to the second ?
