Gigabit Interface Converter-Shortwave
Two Gigabit Interface Converter-Shortwave (GBIC-SW) modules are required
for each Fibre Channel cable installed. Two GBIC-SW modules are provided
with each RA4000/4100, RA4000 Controller, and host bus adapter.
GBIC-SW modules hot-plug into Fibre Channel storage hubs, array
controllers, and host bus adapters. These converters provide ease of expansion
and 100 MB/s performance. GBIC-SW modules support distances up to
500 meters using multi-mode fibre optic cable.
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 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: MSCS requires TCP/IP as the cluster communication protocol. When
configuring the interconnects, be sure to enable TCP/IP.
Client Network
Every client/server application requires a local area network, or LAN, over
which client machines and servers communicate. The components of the LAN
are no different than with a stand-alone server configuration.
Because clients desiring the full advantage of the cluster will now connect to
the cluster rather than to a specific server, configuring client connections will
differ from those for a stand-alone server. Clients will connect to virtual
servers, which are cluster groups that contain their own IP addresses.
Within this guide, communication between the network clients and the cluster
is termed
cluster-to-LAN communication .
