Network-Attached Cluster

Network-attached clusters provide configuration flexibility, expandability, and

performance. In a network-attached cluster, all of the nodes (server modules)

are attached to redundant switch fabrics. A network-attached cluster supports

the following configurations:

•

One or two storage systems using embedded switch fabrics

•

Up to four storage systems using external fabrics

Figure 1-4 shows the network-attached cluster connected to an external SAN

using embedded switch modules.

Figure 1-5 shows the network-attached cluster connected to an external SAN

using embedded pass-through modules.

Figure 1-6 shows the network-attached cluster connected to an external SAN

using embedded switch modules

NOTE:

Figure 1-4 through Figure 1-6 are for illustration only. Some cluster connections

shown below are routed internally through the PowerEdge server enclosure.
