Cabling Your Cluster Hardware 15
Cabling the Storage System
This section provides information on cabling your cluster to a storage system
in a SAN-attached configuration.
Cabling a Cluster to a Compellent Storage Center Storage System
A SAN-attached cluster is a cluster configuration where all cluster nodes that
are attached to the storage system through SAN use a redundant switch
fabric.
SAN-attached cluster configurations provide flexibility, expandability, and
performance.
For more information on Fibre Channel switch fabrics, see "Implementing
Zoning on a Fibre Channel Switched Fabric" on page 28.
Figure 2-3 shows an example of a two node SAN-attached cluster.
Figure 2-4 shows an example of an sixteen-node SAN-attached cluster.
Similar cabling concepts can be applied to clusters with different number of
nodes.
NOTE: The connections listed in this section are representative of one proven
method of ensuring redundancy in the connections between the cluster nodes and
the storage system. Other methods that achieve the same type of redundant
connectivity may be acceptable.
