In a Dell PowerEdge high availability cluster configuration, each server

module requires at least one expansion card. Expansion cards for either Fibre

Channel or Gigabit Ethernet (for iSCSI) are available, and allow the server

module to communicate with the shared storage system for the cluster. The

expansion cards, also known as daughter cards or mezzanine cards, are

installed on the server module and contain two I/O ports. These I/O ports are

internally connected to two separate I/O modules in the server enclosure.

By attaching to two separate I/O modules, an expansion card can provide

redundant paths and load balance the I/O from the server module to the

shared storage system(s) for the PowerEdge cluster solution. Table 1-1

outlines the number of expansion cards that are available on each supported

server module.

Each server module is also configured with two additional Ethernet ports for

cluster interconnects. These are internally connected to two separate Gigabit

Ethernet pass-through or Gigabit Ethernet switch modules in the server

enclosure. With certain server modules, it is also possible to configure

additional Ethernet ports, which can enable the use of NIC teaming on the

cluster public network.

For a list of supported Fibre Channel and iSCSI daughter cards, see the

Platform Guide for your PowerEdge cluster located on the Dell Support

website at support.dell.com.
