Internally the array is probably O.K. - is that going to be affected by the fact that there will be a number of other machines also attached to the array ? Got 2 BSD machines for starters and possibly 5 windows machines. I am unsure of FC topology - will all of them be point-ot-point into the array ? > arbitrated-loop, but that should not be a concern to you. Fibre Channel is a Makes mental note to go research arbitrated-lopp vs point-to-point! Does this affect the kind of card I acquire ?

Curtis Preston's _Introduction to SAN and NAS_ (published by O.K., that helps a lot - if its just acting as an alternative SCSI transport as far as th OS ins concerend then that makes me a lot happier. Thanks for the advice. -pcf.
