Add grid nodes to add capabilities to your system

You can add redundancy or additional capabilities to a StorageGRID system by adding new grid nodes to existing sites.

For example, you might choose to add Gateway Nodes to use in a high availability (HA) group, or you might add an Admin Node at a remote site to permit monitoring using a local node.

You can add one or more of the following types of nodes to one or more existing sites in a single expansion operation:

  • Non-primary Admin Nodes

  • Storage Nodes

  • Gateway Nodes

When preparing to add grid nodes, be aware of the following limitations:

  • The primary Admin Node is deployed during the initial installation. You can't add a primary Admin Node during an expansion.

  • You can add Storage Nodes and other types of nodes in the same expansion.

  • When adding Storage Nodes, you must carefully plan the number and location of the new nodes. See Guidelines for adding object capacity.

  • If the Set new node default option is Untrusted on the Untrusted Client Networks tab on the Firewall control page, client applications that connect to expansion nodes using the Client Network must connect using a load balancer endpoint port (CONFIGURATION > Security > Firewall control). See the instructions to change the security setting for the new node and to configure load balancer endpoints.
