    I have a 667 MHz XP900/DS10 alphaserver running Tru64 5.1B that
    currently has three internal ultra-2 SCSI disks (two 9.1 GB and
    one 18.2 GB) attached to a KZPCA-AX PCI SCSI adapter card.
    This setup works fine. However, I need more disk space, so I want
    to replace one (or perhaps both) of the 9.1GB drives with larger
    drives. My questions are:

    - what's the max single disk size that the KZPCA-AX controller can handle?
      Can it take 36.4GB disks ?
    - what is the maximum total internal disk capacity on this system ?
    - any suggestions for which HP/Compaq part numbers to look for ?

    I also have a second PCI SCSI adapter card (KZPBA-CX) spare that
    I could add in to the system, if that would help.
    (BTW my understanding is that the KZPCA-AX and KZPCA-AA adapters
    are essentially the same, being a Symbios SYM8952U).

    Thanks for any suggestions.

    Martin
