Expansion overview

You can expand a StorageGRID Webscale system by adding storage to virtual Storage Nodes, adding new virtual or appliance grid nodes to an existing site, or adding a new data center site. You can perform expansions without interrupting the operation of your current system.

As shown in the workflow diagram, the basic steps for performing each of the three types of expansions vary slightly, depending on whether your StorageGRID Webscale deployment uses hosts running VMware or Linux.
Note: NetApp-provided virtual machine disk files and scripts for new installations or expansions of StorageGRID Webscale on OpenStack have been deprecated. To expand an existing deployment on OpenStack, refer to the steps in this guide for your Linux distribution.
Note: This guide uses "Linux" to refer to a Red Hat® Enterprise Linux®, Ubuntu®, CentOS®, or Debian® deployment. Use the NetApp Interoperability Matrix Tool to get a list of supported versions.
