Hello,
I have a customer who wants guidance on load balancing exchange 2010 and enterprise vault. I searched but could not find any technote related to this. Any articles/technotes will be appreciated.
Thanks !!

Typically not, however you may run in to a couple of issues....
Some older load balancers had an issue where you needed to apply a hotfix, otherwise it would disconnect the session prematurely. i think that was regarding the F5 firewalls.
A couple of other things to note:
Exchange 2010 introduces a "Throttling" policy, basically giving Exchange a set of rules of how long a user can perform queries in AD, Exchange, LDAP etc, if this isn't configured properly, and EV is doing a long query such as user address lookups, Exchange will forcefully disconnect the user.
Although you cna set the throttling policies on Exchange, the load balancer itself may say that the user has been connected for too long and kill the connection itself

If you have a lot of connectivity issues, would suggest using the ExchangeGCOverride in the ExchangeServerEntry table to point to a hard coded CAS server, don't use the HOSTS file as the tecnote suggests because thats a horrible solution

As part of the Exchange 2010 environment, my customer is introducing a hardware load balancer to front end the CAS role. Does EV need reconfiguring in any way for this?
