Galaxy Repository node server recommendations

The Galaxy Repository (GR) node is the computer where the Galaxy Repository resides. It is a SQL Server database in which all of the galaxy configuration data is stored.

When deciding where to deploy it, consider:

• When deploying a Galaxy, high-sustained CPU usage will occur on the node running the associated SQL Server.

• The GR should be available to the Galaxy.

For this reason, it is recommended that the GR Node Server be on the Report Server or on the Engineering station. It is recommended that the GR Node Server not be on any of the production servers (Production Database Server, Application Server, or Terminal Server).

Note: The GR is not needed at runtime. With the GR node, an object or a view node subscribing for an object attribute is made significantly faster because the GR node knows where everything is located. Otherwise the node with the subscription request has to ping all other nodes’s engines to determine whether they host this object’s attribute.
