## Important 

This parameter is deprecated, and is subject to removal in a future release. Use the HostName  parameter instead. 

The node ID for this node can be given out only to connections that explicitly request it. A management server that requests “any”  node ID cannot use this one. This parameter can be used when running multiple management servers on the same host, and HostName  is not sufficient for distinguishing among processes. Intended for use in testing. 

• HostName

Specifying this parameter defines the hostname of the computer on which the data node is to reside. To specify a hostname other than localhost , either this parameter or ExecuteOnComputer  is required. 

• ServerPort

Each node in the cluster uses a port to connect to other nodes. By default, this port is allocated dynamically in such a way as to ensure that no two nodes on the same host computer receive the same port number, so it should normally not be necessary to specify a value for this parameter. 

However, if you need to be able to open specific ports in a firewall to permit communication between data nodes and API nodes (including SQL nodes), you can set this parameter to the number of
