BlackDiamond Management Switch Fabric Module (MSM).
Overview of the BlackDiamond Management Switch
Fabric Module
The Management Switch Fabric Module (MSM) is the internal switch fabric for data being sent between
I/O modules. One MSM is required for switch operation; however, adding more MSMs increases both
reliability and throughput.
Each MSM has two CPUs for protocol processing and network management. For full redundancy, you
can install MSMs as follows:
•
Four MSMs in the BlackDiamond 6816 switch
• Two MSMs in the BlackDiamond 6808 switch
•
Two MSMs in the BlackDiamond 6804 switch
With full redundancy, the BlackDiamond 6800 series switch is a fully nonblocking switch.
Table 52 shows that packet throughput between I/O modules increases when additional MSMs are
installed.
