  • Page 13 The server modules include two integrated Gigabit Ethernet network interface cards (NICs). You must configure at least two networks for each PowerEdge cluster solution. One cluster network is configured for heartbeat communications (private network) and is only accessible to the server modules in the cluster.
  • Page 14 Fibre Channel Module You can configure the PowerEdge blade cluster with two hot-pluggable Fibre Channel switch modules installed on a PowerEdge 1855/1955 system or up to four hot-pluggable Fibre Channel switch/pass-through modules installed on the PowerEdge M1000e system to provide Fibre Channel connection between the server modules and storage system(s).
  • Page 15 Additionally, the Fibre Channel switch module includes an internal serial port that communicates with the DRAC/MC module. The Fibre Channel switch module supports the following configurations: • Network-attached configuration with up to two supported Dell|EMC storage systems • Network-attached connection to an external storage area network (SAN)
  • Page 16: Supported Cluster Configurations

    Supported Cluster Configurations The PowerEdge blade servers support both Fibre Channel and iSCSI cluster configurations using either Fibre Channel mezzanine cards or Gigabit Ethernet mezzanine cards to connect to the corresponding shared storage system in either direct-attached or network-attached environments.
