SPARC: LDoms Guest Domains: Clusters Span Two Different Hosts Topology

In this logical domains (LDoms) guest domain topology, each cluster spans two different Solaris hosts and each cluster comprises one node on each host. Each LDoms guest domain node acts the same as a Solaris host in a cluster. In this configuration, because both clusters share the same interconnect switch, you must specify a different private network address on each cluster. Otherwise, if you specify the same private network address on clusters that share an interconnect switch, the configuration fails.

To learn more about guidelines for using and installing LDoms guest domains or LDoms I/O domains in a cluster, see How to Install Sun Logical Domains Software and Create Domains in Sun Cluster Software Installation Guide for Solaris OS.

The following figure illustrates a configuration in which more than a single cluster spans two different hosts.
