Mirror Persistence vs Connection Mirroring

just trying to figure out the difference between both of them and advantages or disadvantages...     It will be used with Microsoft Remote Desktop.

If the client to RDP VIP connection drops during an LTM failover, the client will automatically retry the connection. As long as you have persistence mirroring enabled, LTM will send the new TCP connection to the original server. And the server will accept the new connection and connect the client to the same virtual session on the RDP server.

 

 

So I don't think the overhead of mirroring connections between LTM peers is worth it as the application handles a TCP connection drop fairly well. I'm not saying you shouldn't use both persistence and connection mirroring for RDP--just that I don't think connection mirroring is a requirement.
