SMCC's industry-leading, midrange multiprocessing SPARCservers now offer
your customers more integrated connectivity than ever before. The SBus
Expansion Subsystem Board provides valuable extra SBus slots to improve
flexibility and expandability for SMCC's midrange servers. Once again
Sun demonstrates that SPARCservers deliver the best value to the customer
with an unmatched combination of application throughput, growth path
and innovation.


Application Throughput:
	- improved application performance by balancing MP configurations 
	  with more disk and network connections

Growth:
	- add more SBus options when needed without slot contention, even
	  with dual MBus module configurations

Innovation:
	- added expansion capabilities are cleanly integrated into system
	  package, no extra boxes required


The SBus Expansion Subsystem Board (SES/B) is a 9U form factor card that
occupies two VME slots in the cardcage of either a SPARCserver 670MP or 690MP.
The SES/B draws power from the VME backplane and connects to the system's
native SBus through an adapter card. The adapter card occupies one slot on
the system SBus, providing a net gain of 3 SBus slots when an SES/B is
installed.


FEATURES AND BENEFITS
---------------------
Features				Benefits
---------------------------------------------------------------------------
Integrated Expansion			* Better reliability and more
					  appropriate for server customers
---------------------------------------------------------------------------
4 SBus slots				* More expansion for server 
					  applications
---------------------------------------------------------------------------
Supports master SBus cards		* Increased flexibility allowing
					  use of master or slave SBus cards
---------------------------------------------------------------------------
Auto-configuration			* SES/B automatically checks address
					  space requirements of SBus cards on
					  board, simplifying system
					  administration/installation
---------------------------------------------------------------------------
Supports burst mode transfers		* Better performance for high speed
					  devices
---------------------------------------------------------------------------
Packet protocol				* More reliable transmission method
					  for error free transfers
---------------------------------------------------------------------------


					  
HARDWARE AND SOFTWARE CONSIDERATIONS
------------------------------------
- SBus Expansion Subsystem Board requires Solaris 1.1 (with SunOS 4.1.3).

- A maximum of 2 SBus Expansion Subsystem Boards are supported on SPARCserver
  670MP and 690MP.

- The following Sun SBus cards are currently not supported on the SES/B:

	FDDI Single Attach			X1003A
 
  Any SBus card currently not supported on SPARCserver 600MP will not
  be supported using an SES/B.

- Booting from an SBE/S installed on the Xboard is not supported.  Use
  the FSBE/S adapter to boot clients off ethernets installed on the SBus
  Expansion Subsystem.	  


Note:

The SES/B requires two VME slots in a cardcage to accommodate the SBus
cards that plug into it. The 630MP only has one 9U slot.
