- Thanks to MDI for the reply to my question about adding additional drives
- to our current system. I didn't mean to imply that SCSI Express was the
- limiting factor to adding more than 42 drives to my current system. I
- understand the limitations but perhaps it was worth stating for the sake
- of the list. I suppose the real question I wanted to ask was:
-
- is there another hardware solution other than purchasing a third server?
