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.
