My customer has 4 data DSAs/user store, then they install router DSAs on each CA SSO policy server; policy server connect to local router DSAs, then traffic is routed to the data DSAs.
There are around 32 policy servers in one data center, so there are 32 router DSAs on those policy server boxes. I don't see benefits to have such a configuration and it is hard to manage so many router DSA instances, but is there any negative impact on performance and system stability with so many router DSAs?
