SGI CDC Hardware

[Dominique Thongs]

        A question to person's with extensive knowledge of SGI hardware.
        
        Has anyone out there installed a CDC 9720 1.23GB Disk on a SGI 4D/50.
        I am looking into the pos. of doing this.
        However, I would like to hear from persons having done this
        as to the ease with which it was accomplished.
        What were the problems encountered ?
        Were there any incompatibility problems between
        the CDC disk and the SMD Controller board ??
        ( I am aware that I need to upgrade controller Board  on 4D/50 first)
        SGI has such an option avail. ( P4-D120D)
        I would like to know what percentage of the CDC DISK'S
        are rejected when they  (SGI) do this option.
        Thanks .
        Any and all responses will be appreciated.
