We have an IBM x-series 345 that we're looking to upgrade, but I'm having a hard time finding out what the limitations of the hard drive controller are (an Adaptec AIC-7902 RAID controller, supporting U320 SCSI disks). The brochure says the maximum disk capacity of the 345 is 880 gigs, which so happens to be 146.6 x 6. And while there are lots of 146 Gig drives out there, there are also 300 gig drives (or, I suspect they are actually 292 gig drives) available, which would be desirable.
Does the Adaptec 7902 controller just support any drive that happens to be a U320 disk, or is there some kind of size limitation?
