Overview of the HP ProLiant Cluster F100 9

For more information, refer to the HBA documentation.

Optical Transceivers

The F100 cluster uses optical transceivers, which convert data that is transmitted and received over a fibre-optic cable. The F100 cluster uses either SFP for the MSA1000 or GBIC-SW for the RA4100.

The transceivers hot plug into switches, Fibre Channel storage hubs, array controllers, and HBAs. The SFP transceiver provides 200 Mb/s performance and the GBIC-SW provides 100-Mb/s performance. The transceivers support distances up to 500 meters using multimode fiber-optic cable.

For more information, refer to the transceiver documentation.

Cluster Interconnect

The cluster interconnect is a data path over which nodes of a cluster communicate. This type of communication is termed intracluster communication. At a minimum, the interconnect consists of two network adapters (one in each server) and a crossover cable connecting the adapters.

The cluster nodes use the interconnect data path to:

•Communicate individual resource and overall cluster status

•Send and receive heartbeat signals

•Update modified registry information

IMPORTANT: TCP/IP must be used as the cluster communication protocol. When configuring the interconnects, be sure to enable TCP/IP.

Client Network

Every client/server application requires a LAN over which client machines and servers communicate. The components of the LAN are no different than with a stand-alone server configuration.
