	    Does anyone know of a SCSI driver for the XL400 machine?

	2) the performance is usually pretty bad compared with the
	equivalent ESDI disk. 

    True, it is *pretty bad* relative to ESDI, but no worse than the *best*
    performance using a SUN for example and certainly better than getting
    the data from some Unix file server (which probably uses SCSI) accross
    Ethernet.  The performance of SCSI is quite acceptable for many uses
    --system source, rarely used files, mail collections, fonts, bitmaps,
    etc.

Do you really use SCSI disks on your Sun file servers?  We use them as
local paging disks on some workstations, but all our file servers use
SMD disks (mostly Sun disks (I'm told they are Hitachis), Eagles,
Super-Eagles, and CDC-515's).
