My understanding was:

The source can be standalone, CCR, or SCC.
The target can be standalone or the pssive node of a cluster that is not a
possible owner of any other CMS.

Thanks Bharat,

I've been lucky enough to talk with an Exchange tech today at Microsoft's
UK
HQ in Reading, here's what I've learnt:

SCR as implemeneted in SP1 will still require clustering.

As explained to me, it effectively allows the active node to Seed and
Log-Ship to a storage area at a seperate datacentre (this is done in
addition
to the seeding/logshipping being done by the passive node).

This offsite copy can then be accessed by a dedicated server at that
site.
My understanding is that the 'recovery' steps need to bring the offsite
service online in the event of the datacentre being unavailable would be
manual ones

Exchange 14 when it's released, will remove the need for MSCS to be used
to
cluster.

Hopefully I'm not speaking out of turn - All of the above are my views
based
on informal chats with Exchange contacts at MS, so please dont take it as
gospel. If it turns out to be mis-information because I haven't
understood I
apologise, but hopefully it'll be of some benefit until more official
info
is available.

All the best,

Darren

I read on the Exchange Team blog site that Standby Continuous
Replication
is
going to provide the facility for Exchange 2007 to run a
geographically
dispersed standby server without the need to stretch the subnet, which
would
normally be needed with a CCR cluster.

The implication is that the MS Cluster Services is done away with - so
no
need for the file share witness role, potentially no need for
Enterprise
software (maybe).

There doesn't seem to be any info yet on how SCR works yet tho -
anybody
heard anything? I presume it uses the same database seeding and log
shipping/transport dumpster technology but that the failover &
recovery is
handled through Exchange Console/Powershell as a manual process. Can't
find
any info on how the server to server comms are done either.

Any info greatly appreciated
