Sub-luns are out - leaving the same old 8 devices, 8 logical units per device.
The maximum single-initiator system therefore consists of the initiator and
up to 56 logical units spread across 7 targets (physical addresses).

The best stuff is coming from conferences:

The annual SCSI Forum from a few months ago has a good set of technical and
trade articles (4" binder) that you can have for a price:

           Joe Molina
           Technology Forums
           PO Box 1729
           Minnetonka, MN 55345
           612-934-1415

The IEEE Systems Design and Networks Conference (Mass Storage Session) held
May 23-25, 1989 also has a nice set of technical papers (1" bound). About
80% of the papers deal with SCSI specifically. Call IEEE for information.

Some (fairly) recent articles I've seen in trade rags:

   "The Quest for the Best", Andy Hospidor
   Mini-Micro Systems, 11/88
   Testing considerations for SCSI disk drives and WORMs.

   "Disk Interfaces for the High End", Peter Aitken
   PC Tech Journal, 2/89
   A comparison of SCSI, ESDI, and SCSI-2 written from a PC perspective.

   "Small Computer System Interface", Paul Q. Perlmutter
   Hewlett-Packard Journal, 10/88
   A SCSI-1 tutorial with comparisons to HP-IB

   "SCSI Port on the VAXstation 2000" 
   Victor Gould
   DEC Professional, March 1989

   "Explore SCSI-2 Command Queues With Debugger"
   Ronald Berg and Mark Gordon 
   Electronic Design, Feb 23, 1989

   Mass Storage Supplement to PC Week
   April 10, 1989
