GSA Unification is also known as dynamic scalability. This section describes use of the federation feed.
Configuring a GSA Unification Network
Retrieve, update, create, or delete the GSA Unification node configuration and retrieve the node
configuration of all nodes in the network on the Google Search Appliance.
Property Description
applianceId The ID of the search appliance, required to identify the node during
node operations.
federationNetworkIP The private tunnel IP address (virtual address) for the node. This
address must be an RFC 1918 address.
Note: A GSA Unification works best when the IP addresses of the nodes
are numerically near, such as 10.1.1.1, 10.1.1.2, 10.1.1.3, and so on. The
search appliance disallows a GSA Unification for nodes that are not in
the same /16 subnet. This is a problem only if there are more than
65534 nodes in a GSA Unification network. GSA Unification nodes
communicate on TCP port 10999.
hostname The host name of the search appliance.
nodeType The type of search appliance. Possible values:
• PRIMARY: The node merges results from other nodes.
• SECONDARY: The node serves results to the other nodes.
• PRIMARY_AND_SECONDARY: The node acts as both a primary and
secondary node.
scoringBias The scoring bias value for this node. Valid values are integers between -
99 and 99. The scoring bias value reflects the weighting to be given to
results from this node. A higher value means a higher weighting. The
values and their equivalent in the Admin Console are:
secretToken The secret token that you use to establish a connection to this node.
This token can be any non-empty string. The remote search appliance
needs this token for the connection handshake.
