Storage Nodes provide disk storage capacity and services.
More information
What a Storage Node is
A Storage Node includes the services and processes required to store, move, verify, and retrieve object data and metadata on disk.
Managing Storage Nodes
Managing Storage Nodes entails monitoring the amount of usable space on each node, using watermark settings, and applying Storage Node configuration settings.
Monitoring storage
Monitoring storage includes looking at total storage capacity, consumed storage, and usable storage. You might want to monitor storage capacity to determine your usable storage for the entire StorageGRID Webscale system or for select data center sites.
Configuring settings for stored objects
You can configure the settings for stored objects, including stored object encryption, stored object hashing, and stored object compression. You can also enable the Prevent Client Modify setting to override the permissions defined for HTTP profiles and to deny specific HTTP client operations.
Mounted storage devices
At installation, each storage device is assigned a file system UUID and is mounted to a rangedb directory on the Storage Node using that file system UUID. The file system UUID and the rangedb directory are captured in the /etc/fstab file.
What object segmentation is
Object segmentation is the process of splitting up an object into a collection of smaller fixed-size objects in order to optimize storage and resources usage for large objects. S3 multi-part upload also creates segmented objects, with an object representing each part.
Verifying object integrity
The StorageGRID Webscale system verifies the integrity of object data on Storage Nodes, checking for both corrupt and missing objects.
How load balancing works
To balance ingest and retrieval workloads, optionally deploy the StorageGRID Webscale system with API Gateway Nodes, or integrate a third-party load balancer.
