8.2.1 Confirming the expansion pattern


8.2.1 Confirming the expansion pattern
Figure 8-1 and Figure 8-2 show the expansion patterns of building block configurations. The necessary tasks vary depending on the expansion pattern. Check which pattern applies to your case. For details on system configurations, see the Fujitsu M10/SPARC M10 Systems Quick Guide.
Figure 8-1  Expansion patterns of building block configurations (up to the 8BB configuration)
Figure 8-1  Expansion patterns of building block configurations (up to the 8BB configuration)
Figure 8-2  Expansion patterns of building block configurations (up to the 16BB configuration)
Figure 8-2  Expansion patterns of building block configurations (up to the 16BB configuration)
In the above figures, "BB" indicates the SPARC M10-4S and "XBBOX" indicates a crossbar box. The patterns in the figures correspond to Table 8-1.
Note - The crossbar box (XBBOX), when shipped, is mounted in a dedicated rack (expansion rack) together with dedicated power distribution units (PDUs) and crossbar cables (optical). Expansion racks are defined as expansion rack 1 and expansion rack 2 according to expandability.
Table 8-1  Expansion patterns and references
Pattern Expansion description Reference
A Expansion up to the 4BB configuration (direct connections between chassis)
Example:
Expansion from the 1BB configuration to the 4BB configuration
Expansion from the 2BB configuration to the 4BB configuration
"9.2 Adding the SPARC M10-4S"



B (1) Expansion up to the 8BB configuration (connections through crossbar boxes)
Example:
New addition of expansion rack 1.
The connections between the chassis in an existing multiple-BB configuration (direct connections between chassis) are released to change every chassis to the 1BB configuration and add them to expansion rack 1.
"9.3 Adding Expansion Rack 1 (Expansion to Up to the 8BB Configuration)"
B (2) Addition of a new SPARC M10-4S in expansion rack 1 "9.2 Adding the SPARC M10-4S"
C (1) Expansion up to the 16BB configuration (connections through crossbar boxes)
Example:
New addition of expansion rack 2.
The connections between the chassis in an existing multiple-BB configuration (direct connections between chassis) are released to change every chassis to the 1BB configuration and add them to expansion rack 2.
"9.4 Adding Expansion Rack 2"
C (2) Addition of a new SPARC M10-4S in expansion rack 2 "9.2 Adding the SPARC M10-4S"
D Expansion from the 8BB configuration to the 16BB configuration (connections through crossbar boxes)
Example:
New addition of expansion rack 2
