Local Continuous Replication (LCR) on Exchange Server
2007
Local Continuous Replication (LCR) is a single-server solution that uses built-in
asynchronous log shipping technology to create and maintain a copy of a storage group
on a second set of disks that are connected to the same server as the production
storage group.
LCR is not a failover implementation. So GroupShield 7.0 can be installed and used in
a similar way to that of a standalone mailbox server installation.
Clustered Continuous Replication (CCR) on Exchange
Server 2007
Cluster Continuous Replication (CCR) is a high availability feature of Microsoft
®
Exchange Server 2007. It combines the asynchronous log shipping and replay
technology built into Microsoft
®
Exchange Server 2007 with the failover and
management features provided by the Microsoft
®
Cluster service.
Install GroupShield 7.0 on all the nodes of the cluster following the standard installation
steps.
Single Copy Cluster (SCC, N+1 cluster configuration) on
Exchange Server 2003 and 2007
A Single Copy Cluster (SCC) is a clustered mailbox server that uses shared storage in
a failover cluster configuration to allow multiple servers to manage a single copy of the
storage groups. This is built on the failover and management features provided by the
Microsoft
®
Cluster service. The Exchange Virtual Server uses its own network identity
and not the identity of any node in the cluster. This network identity is referred to as a
clustered mailbox server.
Both Exchange 2007 Mailbox server and Exchange 2003 can be deployed in this type
of cluster.
Install GroupShield 7.0 on all the nodes of the cluster following the steps of standard
installation.
Note
On an Exchange 2007 CCR Cluster, GroupShield for Exchange 7.0 will not be cluster
aware application. A resource type for GroupShield for Exchange 7.0 will not be
available in the
Cluster Administrator
and cannot be added to the Exchange Virtual
Server. GroupShield for Exchange 7.0 on all nodes of the cluster must be configured
independently and will work as standalone instances.
Note
GroupShield for Exchange 7.0 should be added to the Cluster groups where the
Exchange virtual server is present after the installation on the nodes of the cluster.
