Re: Exchange Management Console slow

SCC is not just implemented to protect against hardware failure, it
also provides protection against failure of the OS and its
applications and the argument of businesses making mistakes in their
"design, deployment or administration" is also applicable to CCR
implementations.

Even though MNS requires nothing more than FSW and a fileshare on
another server, it is still an extra requirement and dependancy on the
MNS architecture. The network argument comes from capacity management
of bandwith. Yes its cheap but it is still a consideration. You now
have essentaily double the exchange traffic going through your
switches, and I dont think you can compare the size of a heartbeat
packet to the size of actual messaging packets that are being
replicated between the servers. Besides most people would use an
isolated network or a dedicated cross over cable as their primary
heartbeat network which places no impact on the production network
infrastructure and remove the production network as a point of failure
for cluster communications.

As far as array based snapshots goes, most SANs give you the ability
to take a point in time copy of an exchange database, which can be
used in the case of database corruption.
