Google Search Appliance: Getting the Most from Your Google Search Appliance Setting Up 13
After you complete the installation process, record the identification number of the search appliance,
which is useful in troubleshooting if the search appliance experiences any problems. You can find the
appliance ID in the following places:
• On the label on the back of the search appliance
• On the Administration > License page in the Admin Console (see “Using the Admin Console” on
page 61)
• On the Google for Work Technical Support web site, if you log in with the credentials used for your
Technical Support account
If the search appliance experiences any problems during installation or configuration, attach a monitor
directly to the search appliance. The search appliance displays messages on the monitor indicating the
progress of the start-up process and when the process is complete.

Google Search Appliance.
Configuring Search Appliances for Load Balancing
or Failover
After your Google Search Appliance has been deployed, it may experience a high volume of search
queries, which might affect performance. You can improve performance by configuring load balancing.
Load balancing distributes network traffic of a particular type to two or more instances of an
application, dividing the work load between the instances. A load balancer is a software or hardware
application that distributes network traffic.
Load balancing requires two Google Search Appliances. When you configure two Google Search
Appliance systems for load balancing, search queries are distributed between the two systems. For load
balancing, you can choose one of the following configurations:
• A configuration where there is a physical connection between the search appliances and the load
balancer. Each search appliance is on the same network or subnet as the load balancer.
• A configuration where there is a logical connection between the search appliances and the load
balancer. Each search appliance is potentially on different networks or subnets from the load
balancer.
Google does not recommend specific load balancers to use with the search appliance.
With two Google Search Appliances, you can also configure your systems for failover. In this
configuration, the first search appliance responds to search queries. If the first search appliance fails,
the second search appliance starts responding to search queries.
