Power Cabling the NAS SCSI Cluster Solution
Dell™ PowerVault™ NAS SCSI cluster configurations require cabling for the storage systems, cluster interconnects, client
network connections, and power connections.
Cabling the NAS SCSI Cluster Solution
The cluster systems and components are interconnected to provide four independent functions as listed in Table 3-1 , each of
which is described in more detail throughout this section.
Table 3-1. Cluster Cabling Components
Components Description Connection
Shared storage
system
Connects the host-based,
RAID controller(s) to the disk
enclosure(s).
Connect a Dell SCSI cable from the PERC controllers in the PowerVault
NAS systems to each PowerVault 21xS or 22xS storage system that is
cabled to the cluster.
Cluster
interconnect
(private network)
Connects the NAS systems to
each other to exchange
information and status.
For point-to-point Fast Ethernet, connect a crossover Ethernet cable
between the Fast Ethernet network adapters in both cluster nodes.
For point-to-point Gigabit Ethernet, connect a standard Ethernet cable
between the Gigabit Ethernet network adapters in both cluster nodes.
Network
connection for
public traffic
(public network)
Provides a connection between
each cluster node and the
client network.
See the Platform Guide for a
list of supported network
adapters for your
configuration.
Connect an Ethernet cable from the client network to the public
network adapter connector on the back of the system.
Power connection Provides a connection between
the power source and the
power supplies in your system.
Connect the power strips or power distribution units (PDUs) to separate
AC circuits. When you are finished, connect each power supply in your
PowerVault systems to the separate power strips or PDUs.
Cabling One PowerVault 21xS or 22xS Shared Storage System to a NAS
SCSI Cluster
NOTE: See " Configuring the PowerVault 22xS Storage System for Cluster Mode " for more information about
configuring the storage systems.
NOTE: Ensure that you securely tighten the retaining screws on all SCSI connectors to ensure a reliable connection.
NOTICE: Do not turn on the systems or the storage system(s) until the split-bus module on the back of the
PowerVault system has been set to cluster mode and all cabling is complete.
