Re: Ex2007 and Multiple Sites

- CCR cannot be configured between 2 independent Exchange servers already
hosting mailboxes.
- You need to setup a Windows Server 2003 cluster using MNS (Majority Node
Set) quorum - consisting of 2 nodes and 1 file-share witness, and then setup
the Clustered Mailbox Server role on both the servers. Active/Active
clustering is no longer supported with Exchange Server 2007.
- CCR may be possible across WAN links, but both the nodes need to reside on
the same subnet, which requires the use of VLANs to have the subnet span
over 2 sites (afaik).
- In any case, I'm hoping you're simply testing this and not using it in
production yet. Exchange Server 2007 has not RTMed yet - as of now the only
supported way of doing this is if you are part of any of Microsoft's early
deployment programs like RDP or TAP. In that case, Microsoft provides the
required support to enable you to setup CCR.

hi,

I have two data centers and 4 Exch 2007 Ent servers. The roles are:
1) Mailbox and hub transport servers at data center1
2) Client Access Server at data center1
3) Mailbox and hub transport servers at data center2
4) Client Access Server at data center2

I have 2 storage groups and 14 DBs per server and 100 mailboxes per db.
The
data centers are connected via a sonet (1gb+

How do I configure log shippping, etc. between the servers so that if one
fails I can bring the other online to handle the mailboxes? During a
failure, instead of only having 14DB and 700 mailboxes per server the
operational box would have 28dbs and 1400 mailboxes. My client access
servers should then know what server the mailboxes reside on since that is
one of their purposes. Can CCR be configured to do this? I have read
that
CCR is used with clustering but when both servers are in same data center.
In my case the data centers are dispersed. How do I accomplish this. Any
MS articles?

My IPs are 10.55.10.x for
one data center and 10.155.10.x at the other. Subnet is 255.255.255.0.

But can I still split workload between the data centers and have mailboxes
live on both servers, but still CCR datacenter1 to datacenter2 and then
datacenter2 to datacenter1? So when one server hosting 700 mailboxes goes
down the other will pick up load of other server while still handling its
700 mailboxes.
