NimbostratusExchange 2010 CAS Array - 2 Sites
I have a question regarding CAS arrays in 2010.
We have two sites: * Pair of LTM's at each site * One GTM at each site * 2 Exchange nodes per location (CAS, mailbox, etc al...

NimbostratusSo here is what I have done.. I'm really hoping someone can give me some feedback here that has more knowledge in this area:
SITE A:
* Created a CAS array with FQDN of "array-siteA.domain.com"
SITE B:
* Created a CAS array with FQDN of "array-siteB.domain.com"
On the LTM's at each side there are three VIP's which handle RPC - one for MAPI, one for Address Book, and one for the RPC endpoint mapper. These VIPs are fronted by GTM's at each location, and the Wide-IP for this service is "array.domain.com." Then, I simply created two CNAMEs for "array-siteA" and "array-siteB" to point to "array.domain.com" Therefore, array.domain.com points to whichever site is active at the moment as determined by GTM.
Does this sound correct?
