Storage

As files are ingested through the FSG, they are cached locally and forwarded to the grid for persistent storage. The FSG maintains the file system directory tree locally. Payload data is stored in the grid, making the file system appear to have very high capacity, even though the FSG server itself has relatively modest local resources.

This component provides data on the service’s storage space, and the objects cached and processed.
