When you deploy a services appliance as a primary Admin Node, you use the StorageGRID Appliance Installer included on the appliance to install the StorageGRID software, or you upload the software version you want to install. You must configure and deploy the primary Admin Node before you deploy any other appliance node types. Only one primary Admin Node is allowed per grid.
A primary Admin Node can connect to the Grid Network, the Admin Network, and the Client Network.
