Exchange 2010 CAS Array - 2 Sites
We have two sites:
* Pair of LTM's at each site
* One GTM at each site
* 2 Exchange nodes per location (CAS, mailbox, etc all on one server)
We have to support RPC/MAPI for our Outlook clients. My question regarding the CAS arrays: According to the documentation, I have to create two CAS arrays - one for each site/location.
I want the wide-IP for the MAPI/RPC related services to be mapi.domain.com. So, I thought I needed to create both CAS arrays with the FQDN of mapi.domain.com, but apparently you cannot have two CAS arrays with the same FQDN?
Do I need to just create CNAME's named mapi-location1.com and mapi-location2.com which point to mapi.domain.com (the Wide-IP)? Then, use mapi-location1/location2.domain.com as the FQDNs for the CAS arrays?
