I'm currently doing my first Ex2010 design and have some confusion on the cas role I want to clarify
It's a 3 geographically dispersed site design with decent links but nothing flash, all 3 sites are also defined in AD and all prerequsits are / will be met to go from 2003 to 2010. Client access is currently via outlook 2003 with Outlook 2010 on the horizon but won't happen before Ex2010
1> 2 servers is each site with CAS/HT/MB (in a DAG) roles on both, can I put the load balancer in front of these 2 servers rather than dedicated CAS boxes?
If I don't load balance and a client on server A goes down, DB fails over to Server B does the client fail to reconnect to server B and requires intervention such as running a PS script and a restart of outlook or isn't it that simple?
If I do load balance and a client on server A goes down, DB fails over to Server B does the client just redirect automatically, I've seen comments about the DAG failover happens it asks outlook to restart
I'm at the design phase once I get go ahead I can then start spending time testing senerios but nice to get a design fairly nutted out beforehand
