PoolManager Property Unit

The PoolManager is the core of dCache as it maps files via to dCache to the storage on disk. This component is configured with a hierarchical configuration and the smallest unit of configuration is the property Unit. The Poolmanager groups together many "unit" into a ugroup.

Types of Unit

Units come in 4 types.

  • Storage class

These are explained more throughly further in the page.
