First, my fundamental query is for documentation on the SUN SCSI host
adapters. Is there in fact anything beyond the man page?

The two I'm interested in are the VME->SCSI "si" adaptor for VME bus Sun
4's, and the Sun 4/60 "esp" built in.

I presume that the "si" is more or less the SCSI-1 standard, and the
driver is close to CCS.

The glossy on the 4/60 on the otherhand talks about fast synchrononous
scsi. Does the "esp" in fact implement the draft SCSI-2 standard, and
support the fast synchronous option? Do any of the Sun disks take
advantage of this?  Is the fast SCSI option a driver issue, or is it all
hardware?

Is it possible that a 4/60 would make a better SCSI fileserver than a VME
Sun 4 with the "si"?
