30 Cabling Your Cluster Hardware
Cabling Two Two-Node Direct-Attached Clusters to an MD36x0f Storage System
The following steps are an example of how to cable a two two-node cluster.
1
In the first cluster, connect cluster node 1 to the storage system:
a
Install a cable from cluster node 1 HBA port 0 to the Fibre Channel
port on the MD36
x
0f RAID controller module 0, port In-0.
b
Install a cable from cluster node 1 HBA port 1 to the Fibre Channel
port on the MD36
x
0f RAID controller module 1, port In-0.
2
In the first cluster, connect cluster node 2 to the storage system:
a
Install a cable from cluster node 2 HBA port 0 to the Fibre Channel
port on the MD36
x
0f RAID controller module 0, port In-1.
b
Install a cable from cluster node 2 HBA port 1 to the Fibre Channel
port on the MD36
x
0f RAID controller module 1, port In-1.
3
In the second cluster, connect cluster node 1 to the storage system:
a
Install a cable from cluster node 1 HBA port 0 to the Fibre Channel
port on the MD36
x
0f the RAID controller module 0, port In-2.
b
Install a cable from cluster node 1 HBA port 1 to the Fibre Channel
port on the MD36
x
0f RAID controller module 1, port In-2.
4
In the second cluster, connect cluster node 2 to the storage system:
a
Install a cable from cluster node 2 HBA port 0 to the Fibre Channel
port on the MD36
x
0f RAID controller module 0, port In-3.
b
Install a cable from cluster node 2 HBA port 1 to the Fibre Channel
port on the MD36
x
0f RAID controller module 1, port In-3.
Cabling Storage for Your SAN-Attached Cluster
A SAN-attached cluster is a cluster configuration where all cluster nodes that
are attached to a single storage system or to multiple storage systems through
SAN use a redundant switch fabric.
SAN-attached cluster configurations provide more flexibility, expandability,
and performance than direct-attached configurations.
For more information on Fibre Channel switch fabrics, see "Implementing
Zoning on a Fibre Channel Switched Fabric" on page 45.
Figure 2-6 shows an example of a two node SAN-attached cluster.
Figure 2-7 shows an example of an sixteen-node SAN-attached cluster.
