4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

(In this example, virtual host virtual_acmd1 uses IP address 10.1.1.1 and virtual host
virtual_acmd2 uses IP address 10.1.1.2.)
With this setup, the domain name server sends messages in a round-robin fashion
to the two virtual hosts indicated by the IP addresses, causing them to share the
request load. Each virtual host has a single primary server on which it performs its
work; the other server is a backup in case the primary goes down or is taken offline
for maintenance.
Depending on your needs, more complicated combinations of DNS round robin and
Matrix Server can be used, including cluster configurations with multiple
failover-protected load-balanced servers.
