GSA Unification is also known as dynamic scalability. The federation feed provides GSA Unification
features.
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: 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 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.
