Overview; Servernet Ii Kits - Compaq ServerNet ServerNet II Installation Manual

Overview

The Compaq ServerNetä II System Area Network (SAN) offers point-to-point, wormhole-
routed connections between Compaq ProLiantä servers in clustering environments where
multiple servers are linked together. Wormhole routing, unlike store and forward, allows the
head of the packet to leave the router before the tail arrives, providing lower latency.
ServerNet II improves latency and bandwidth and reduces CPU usage over the previous
ServerNet version. In addition, it lets you create redundant SANs when ServerNet II Adapters
are teamed with ServerNet II Switches. The SAN can contain from two to 12 nodes with one or
two Switches, or it can be configured without a Switch (a switchless SAN). Information about
these configurations is found later in this chapter.
