Re: Recommendations for Clustering?
Given the cost of implementing a CCR cluster (no shared storage or
cluster-certified hardware), CCR for local/same datacenter, and SCR to
remote datacenter.
Neither will provide you load-balancing, or allow a mailbox to be accessed
from multiple locations locallys (e.g. you can't have UserA's mailbox on
ServerA, replicate that to ServerB in remote datacenter, and have it locally
accessible from ServerB as well... ).
Alternatively, you can place a Storage Group with remote users on ServerB,
so it's locally available to those users, and replicate it using SCR to
ServerA in your primary datacenter, where ServerA also hosts mailboxes for
local users in a different Storage Group. (Again, the concept is that the
same mailbox can't be accessed locally from both locations).

Re: Recommendations for Clustering?
Bharat,
Thanks after some reading and then seeing your response, It looks like I
will be doing what you suggest and setting up a second storage group and
then replicating it back to here for backup purposes.
It won't be precisely what I want to do, but it seems to be the best
available option.
Thanks!
