Chapter 13: High Availability
23942C4911, January 2007
Figure 13-8 illustrates a common hot-standby implementation on a single blade server. Notice
that the BladeCenter server NICs are configured into a team that shares the same IP address
across both NICs. Because only one link can be active at a time, the hot-standby feature con-
trols the NIC failover by having the Standby switch disable its internal ports (holding down the
server links).

Task 1: Configure GbESM 1
1. On GbESM 1, configure the interfaces for clients (174.14.20.110) and servers (10.1.1.110).
