BlackDiamond 6800 Series 
Management Switch Module

This chapter describes:

The Management Switch Fabric Module (MSM64i) is the internal switch fabric for data that is being sent 
between I/O modules. One MSM64i is required for switch operation; however, adding more MSM64i 
modules increases both reliability and throughput. 

Each MSM64i has two CPUs for protocol processing and network management. For full redundancy, 
you can install up to:

Four MSM64i modules in the BlackDiamond 6816 switch

Two MSM64i modules in the BlackDiamond 6808 switch

Two MSM64i modules in the BlackDiamond 6804 switch

With full redundancy, the BlackDiamond 6800 series switch is a fully nonblocking switch.

Table 67 shows that packet throughput between I/O modules increases when additional MSM64i 
modules are installed.
