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

capability of Matrix Server to accept the round-robin requests sent by the DNS. Matrix
Server handles the failover function to the real servers in the cluster.
Following is a simple example to demonstrate this capability. (The example may not
be applicable to your specific usage environment.) In the example, two servers,
acmd1 and acmd2, are configured to accept round-robin requests.
The addresses on the domain name server are virtual_acmd1 and virtual_acmd2.
Two virtual hosts have also been created with those names. The first virtual host uses
acmd1 as the primary server and acmd2 as the backup. The second virtual host uses
acmd2 as the primary and acmd1 as the backup.
The DNS server is configured for round robin using the following A records:
IP AddressRecord TypeServiceTime to LiveAddress
10.1.1.1AIN60www.acmd.com.
10.1.1.2AIN60www.acmd.com.
Address: The virtual hostnames that customers use to send requests to your site. (The
period following the “.com” in the address is required.)
Time to Live: The number of seconds an address can be cached by intermediate DNS
servers for load balancing. This value should be relatively brief so that the addresses
of non-functioning servers are not cached by intermediate DNS servers for long
periods of time.
Service: Always IN for internet.
Record Type: Always A for address.
IP address: The IP addresses for the virtual hosts you will use for each server in the
cluster. These are the IP addresses that the DNS will use to send alternate requests.
