Cabling cluster hardware

Cluster configurations require cabling for the storage systems, cluster interconnects, client network

connections, and power connections.

Cabling for the cluster Solution

Components

Description

Shared storage system

Connects the host-based, RAID controller to the disk enclosure. This

interconnect is made from the PERC 4e/DC card in each PowerEdge system to

the Dell PowerVault™ 220S EMMs, using Dell-qualified U320 SCSI cables.

Cluster interconnect

(private network)

Connects the systems to each other to exchange information and status. This

connection can be made by using a supported Ethernet network adapter and

crossover cabling connected to each cluster node.

Network connection for

public traffic (public

network)

Provides a connection between each cluster node and the client network. This

connection can be made using an Ethernet network adapter and cabling that is

connected to the public network.

Power connection

Provides a connection between the power source and the power supplies in

your system.

Cabling PowerVault 220S Shared Storage System to a Cluster

1) Connect the SCSI connector A (see Figure 2) on the back of the PowerVault 220S storage system

to the 68-pin connector on the first SCSI cable (see Figure 3), and then tighten the retaining

screws.

2) Connect the very high-density connector interface (VHDCI) connector of the first SCSI cable to

the channel 0 connector on the cluster-enabled PERC RAID adapter in the first PowerEdge system

(see Figure 3), and then tighten the retaining screws.

3) Connect the VHDCI connector of the second SCSI cable (see Figure 3) to the channel 0 connector

on the cluster-enabled PERC RAID adapter in the second PowerEdge system, and then tighten the

retaining screws.

4) Connect the SCSI connector B (see Figure 2) on the back of the PowerVault 220S storage system

to the 68-pin connector on the second SCSI cable (see Figure 3), and tighten the retaining screws.
