Types of cluster IP addresses in SCC/SCR setup

Hi

We are running Exchange 2007 SP3 and one of our servers is set up as below:

HQ site:

Active/Passive SCC cluster using Windows 2008 Server
Node1: Server1.domain.com
Node2 Server2.domain.com
CMS: mailserver.domain.com
CMS IP: 192.168.1.5

DR Site:

Node1: Server10.domain.com

Now, if I look at Failover Cluster Management on either Node1 or Node1 in the HQ site, I see the following:

The CMS is set up as a "Service or Application" in Cluster Manager, for the Cluster named CLUSTER1. It has a an Name resource (mailserver) and an IP (192.168.1.5)

But in Cluster Core Resources, there is also a resource named CLUSTER1 with IP 192.168.1.4

Likewise, if I look at the DR node, I can see a Cluster named CLUSTER2 with a service named mailserver. Within this there is "Other Resource" of IP address 192.168.2.5. Also, under Cluster Core resource, there is the resource named CLUSTER2 with IP 192.168.2.4

Could someone explain what these all mean? And am I correct in thinking that when we fail the CMS over to the SCR node, the "Other Resources" IP address (192.168.2.5) becomes the CMS IP? And Exchange installs the CMS Name resource on there too?

Windows Failover clustering creates a default cluster group "Cluster Group"
Then when you install Exchange it creates the Exchange virtual server within a new group
Each cluster group requires a unique IP address

When your SCR moves to the DR site the only IP that matters is the one for the Exchange virtual server

Hi

Thanks...so I assume it's the Cluster Group resources I see in Cluster Core? What exactly does this IP do?
