Hi,
Connection mirroring is used to ensure that the peer LTM has a corresponding connection table for each mirrored connection that the primary unit has. This allows the peer unit to handle existing connections in the event of a failover. Persistence is a mapping of a client to a particular pool member.
For long lived connections like RDP, it would be good to use persistence mirroring. As RDP handles TCP connection loss gracefully (the server allows the client to resume their application session from where it was left off after establishing a new TCP connection), I don't think you really need to use connection mirroring on LTM.
Anyone else have suggestions on this?
