Overview of expansion procedure

The basic steps for performing a StorageGRID expansion vary for the different types of expansion: adding storage volumes to a Storage Node, adding new nodes to an existing site, or adding a new data center site. In all cases, you can perform expansions without interrupting the operation of your current system.

The type of node that you are adding to the grid or the reason that you are adding nodes does not affect the basics of the expansion procedure. But as shown in the workflow diagram, the steps for adding nodes vary slightly depending on whether you are adding StorageGRID appliances or hosts running VMware or Linux.
Note: NetApp-provided virtual machine disk files and scripts for new installations or expansions of StorageGRID on OpenStack are no longer supported. To expand an existing deployment on OpenStack, refer to the steps for your Linux distribution.
Note: Linux refers to a Red Hat® Enterprise Linux®, Ubuntu®, CentOS, or Debian® deployment. Use the NetApp Interoperability Matrix Tool to get a list of supported versions.
