Cabling Your Cluster Hardware 21
Cabling Three or Four PowerVault 22xS Storage Systems to a Cluster SE500W
To connect the cluster to three or four PowerVault 22xS storage systems, repeat the process
described in the preceding section for a second controller.
NOTICE: If you have dual storage systems that are attached to a second controller, Dell supports disk
mirroring between channels on the second controller. However, Dell does not support mirroring disks on
one cluster-enabled PERC RAID adapter to disks on another cluster-enabled PERC RAID adapter.
Cabling Your Public and Private Networks
The network adapters in the cluster nodes provide at least two network connections for each
node. These connections are described in Table 2-2.
Table 2-2. Network Connections
Network Connection Description
Public network All connections to the client LAN.
At least one public network must be configured for Mixed mode for
private network failover.
Private network A dedicated connection for sharing cluster health and status
information between the cluster nodes.
Network adapters connected to the LAN can also provide redundancy at
the communications level in case the cluster interconnect fails. See your
MSCS documentation for more information on private network
redundancy.
