Cluster planning
Successful cluster planning includes:
•Storage planning
•Network planning
•Protocol planning
Storage planning
For clustering, a basic disk must be designated for the cluster and configured as the Quorum disk.
Additional basic disks are presented to each cluster node for data storage as physical disk resources. The physical disk resources are required for the basic disks to successfully work in a cluster environment, protecting it from simultaneous access from each node.
The basic disk must be added as a physical disk resource to an existing cluster group or a new cluster group needs to be created for the resource. Cluster groups can contain more than one physical disk resource depending on the
NOTE:
The LUN underlying the basic disk should be presented to only one node of the cluster using selective storage presentation or SAN zoning, or having only one node online at all times until the physical resource for the basic disk is established.
In preparing for the cluster installation:
•All shared disks, including the Quorum disk, must be accessible from all nodes. When testing connectivity between the nodes and the LUN, only one node should be given access to the LUN at a time.
•All shared disks must be configured as basic (not dynamic).
•All partitions on the disks must be formatted as NTFS.
Network planning
Clusters require more sophisticated networking arrangements than stand alone storage systems. A Windows NT domain or Active Directory domain must be in place to contain the cluster names, virtual server names, and user and group information. A cluster cannot be deployed into a
All cluster deployments have at least six network addresses and four network names:
•The cluster name (Unique NETBIOS Name) and IP address
•Node A's name and IP address
•Node B's name and IP address
•At least one virtual server name and IP address for virtual server A
•Cluster Interconnect static IP addresses for Node A and Node B
