msm use one? or two?

I use the BD8810.

What is the performance difference between when the MSM used only one and dual MSM used ?

Hi,
As JaeChul said, this is not only for redundancy. MSM have both Management and Fabric role. 2 MSMs give a 1+1 redundancy for Management, but you need both MSM to achieve the highest throughput. They are both active for Fabric role.

Indeed. Dual MSM's for redundancy.

One MSM fails, the other one takes over right away.

[JaeChul_Jung]

Yes. Dual MSMs is performed redundancy and process packets at the dual MSM. If one single MSM falls to half the packet throughput.
