32 Cabling Your Blade Cluster Hardware
Network-Attached Cluster
A network-attached cluster is a cluster configuration where all cluster nodes
are attached to a single storage system or to multiple storage systems through
a network using a redundant switch fabric. Network-attached cluster
configurations provide flexibility, expandability, and performance with either
iSCSI or Fibre Channel storage arrays.
Network-Attached Cluster Configured With an Internal Fabric
An internal fabric incorporates switch modules that do not connect to
external switches. Each server module I/O port is internally connected to a
port on a switch module. Up to two storage systems can be connected to the
outgoing ports on a switch module with internal fabric.
Cabling One PowerEdge Server Enclosure to One Storage System
In this configuration, a PowerEdge M1000e server enclosure is connected to
Dell|EMC CX3-20 storage system. The server and storage components in
your configuration may vary.
To cable one PowerEdge server enclosure to Dell|EMC CX3-20 storage
system:
1
Connect a cable from Fibre Channel switch module 1 to SP-A fibre port 0
(first fibre port).
2
Connect a cable from Fibre Channel switch module 1 to SP-B fibre port 1
(second fibre port).
3
Connect a cable from Fibre Channel switch module 2 to SP-A fibre port 1
(second fibre port).
4
Connect a cable from Fibre Channel switch module 2 to SP-B fibre port 0
(first fibre port).
Figure 2-3 shows how to cable a PowerEdge M1000e sever enclosure to the
CX3-20 storage system. The server module’s dual-port Fibre Channel
daughter card and Fibre Channel switch modules are connected internally in
the system chassis.
