You can install and configure InfoScale Storage and Exchange Server in a Microsoft campus cluster.

This configuration workflow describes a two-node campus cluster with each node at a separate site.

The procedures for setting up a campus cluster are nearly the same as those for local clusters, with the following differences:

A campus cluster has the nodes located in separate buildings. Therefore, the hardware setup requires SAN interconnects that allow these connections.
In a campus cluster, each node has its own storage array rather than having a shared storage array between the two clusters.
Both local clusters and campus clusters have SFW dynamic disk groups and volumes, but the volumes on each campus cluster node are mirrors of one another. Each disk group must contain the same number of disks on each site for the mirrored volumes.
For campus clusters, you enable site allocation, assigning disks to one or the other campus cluster sites.

Action

Description

Understand the configuration

See Planning your campus cluster configuration.

Configure the storage hardware and network

Set up the storage hardware for a cluster environment.
Verify the DNS entries for the systems on which Exchange will be installed.

See Configuring the storage hardware and network.

Establish a Microsoft cluster

For details, refer to the Microsoft documentaiton.

Connect the two campus cluster nodes after setting up the Microsoft cluster.

See Campus cluster: Connecting the two nodes.

Install InfoScale Storage with the Microsoft Failover Cluster option

For more information, see the Veritas InfoScale Installation and Upgrade Guide.

Configure and manage disk groups and volumes

Use the VEA console to create disk groups and volumes for the application and for the quorum resource.

See Tasks for configuring InfoScale Storage.

Ensure that the disk group you configure on each site contains the same number of disks and that you configure mirrored volumes.

See Considerations when creating disk groups and volumes for a campus cluster.

After creating the disk group, add the disks to a campus cluster site to enable site allocation.

See Adding disks to campus cluster sites.

Note:

Setting up a Microsoft failover cluster creates physical disk resources for all the basic disks on the shared bus. To use these disks when you create your SFW cluster disk groups, you must first remove the physical disk resources from the cluster. Otherwise, a reservation conflict occurs.

Implement a dynamic mirrored quorum resource

Create a dynamic cluster disk group with a mirrored volume for the quorum disks.
Create a Volume Manager Disk Group (VMDG) resource for the quorum disk group.
Change the cluster quorum resource to the dynamic mirrored quorum resource.

See Tasks for implementing a dynamic mirrored quorum resource.

Add the VMDG Resource for the First Storage group

Add the VMDG disk group resource(s) for the First Storage Group to the quorum group.

See Adding a Volume Manager Disk Group resource for Exchange 2007 installation.

Install Exchange Server

See Installing Exchange Server.

Add the VMDG resources to the Exchange group

See Adding the Volume Manager Disk Group resources to the Exchange group.

Set the database dependency on the disk group resource

See Setting the database dependency on the disk group resource.

Move Exchange databases and logs to shared storage.

See Moving Exchange databases and logs to shared storage.

Verify the cluster configuration

Move the online Exchange Server cluster group to the second node and back to the first node.

See Verifying the Exchange Server group in the Microsoft cluster.
