High Availability for BO Enterprise XI 3.1 how does it work?

Dear colleagues,

we are planning a HA infrastructure for BO with a cluster of 2 nodes running on Windows Server. From documentation I see that HA is implemented using several CMS servers. How does the client's access to the "correct" CMS server work? Is there any kind of relocatible name available? How is the client informed which instance is up? Many thanks in advance.

Best regards,
