Client Access Array - 22.Jul.2010 9:53:09 AM

just wondered how the configuration of the CAS Array settings will effect the users and how they access our 2010 install....

We have 3 sites involved in the implementation -

S00 - hosts TMG, 2 X CAS, 2 x HUB, this is the primary route for smtp, web app, etc

S01 - 2 x CAS, 2 X HUB, DAG1. approx 700 users

S09 - 2 x CAS, 2 x HUB, DAG2. approx 600 users

all is working fine and we have migrated few test users from our current exchange 2007, looking at the configuation of a load balanced cas array, so created the DNS for outlook.domain.us set to the VIP of the NLB for the CAS servers at S01, created the array with site settings of "S01" and then set the mailboxdatabase to use the CAS array address "outlook.domain.us"

all seems fine and I can connect new clients, what I am not sure about is what to do about the rpc client array at site 09 and site 00, if outlook.domain.us uses the VIP address of the S01 NLB then what do I use at the other sites?

many thanks

Hi Jez,

If you want load balanced CAS arrays at every site you'll need to repeat your process at each site.

Obviously this means a unique CAS array name for each site, eg outlook-s01.domain.us and outlook-s09.domain.us

Or outlook.s01.domain.us (you get the idea)

Hope that helps,
