Cabling the Storage Systems

This section provides information for connecting your cluster to a storage

system in a direct-attached configuration, or to one or more storage systems

in a network-attached configuration.

NOTE:

The cluster nodes represent the individual server modules in the

PowerEdge server enclosure. The designations namely, node 1 and node 2 and the

server enclosure are used for illustrative purposes only. The system and the storage

components in your cluster configuration may vary.

In a direct-attached cluster configuration, the redundant

Fibre Channel/iSCSI HBA ports are connected to a supported storage system

using pass-through modules. Two cluster nodes in a direct-attached

configuration can be configured within one PowerEdge server enclosure or

configured between two PowerEdge server enclosures. Direct-attached

configurations are self-contained and do not share any physical resources with

other server or storage systems outside of the cluster.

Each server module is labeled with an identification (ID) number located

above each module on the front of the PowerEdge server enclosure that

corresponds with the identical port number on the pass-through module. For

example, server module 4 connects to port 4 on the pass-through module.

To connect your server modules to a storage system in a direct-attached

configuration:

1 Identify the server modules that you wish to configure in a direct-attached

configuration.

2 Locate the identification number for each server module you selected in

step 1.

3 Match the server module identification numbers with the corresponding

port numbers on the pass-through module.

4 Connect cables from the selected ports to the appropriate SPs in the

supported storage system.

NOTE:

Figure 2-2 illustrates a PowerEdge 1855/1955 server enclosure configured

with a Dell|EMC CX3-10c storage enclosure. You can use a similar configuration

model for other supported server modules, server enclosures, and storage arrays.
