SM: the supported configuration of SM LB and HW LB

Customer is building an environment with both SM LB and HW LB.
They are planning to load balancing the SM app servers (#1 and #2) by using both a Hardware Load Balancer (HWLB) and the SM Software Load Balancer (SWLB).
Like below:

SM APP VIP(HWLB)
/ \
SM LB#1 SM LB #2
SM APP#1 SM APP#2

They want to know whether this kind of configuration is supported or not.


Solution

No, this type of configuration is not supported.
For each deployed SM environment (e.g. Production, Development, Testing, etc) there is only one SM load balancer process allowed.
We cannot run more than one SM load balancer process in a deployed environment.

Load balncing in SM is allowed to be:

1) HWLB only (disable SWLB process)
or
2) SWLB only (disable HWLB) and activate only one LB process (cannot have multiple LB process running)
