Storage Nodes provide disk storage capacity and services. Managing Storage Nodes entails monitoring the amount of usable space on each node, using watermark settings, and applying Storage Node configuration settings.
What a Storage Node is
Storage Nodes manage and store object data and metadata. Each StorageGRID system must have at least three Storage Nodes. If you have multiple sites, each site within your StorageGRID system must also have three Storage Nodes.
Managing Storage Options
You can view and configure Storage Options using the Configuration menu in the Grid Manager. Storage Options include the object segmentation settings and the current values for storage watermarks. You can also view the ports used by Gateway Nodes (CLB service) and Storage Nodes (LDR service) for S3 and Swift clients.
Configuring global settings for stored objects
You can use Grid Options to configure the settings for all of the objects stored in your StorageGRID system, including stored object compression, stored object encryption. and stored object hashing.
Storage Node configuration settings
Each Storage Node uses a number of configuration settings and counters. You might need to view the current settings or reset counters to clear alarms.
Managing full Storage Nodes
As Storage Nodes reach capacity, you must expand the StorageGRID system through the addition of new storage. There are three options available: adding storage volumes, adding storage expansion shelves, and adding Storage Nodes.
