Abstract
A storage array uses paged metadata. Each storage director has access to a plurality of object storage subsystems in a global memory. The object storage subsystems describe locations of paged metadata in backing storage. Each object storage subsystem includes a unique identifier, a pointer to a descriptive data structure that indicates availability of free space for paged metadata for that object storage subsystem, and different types of inodes which describe objects in backing storage. The object storage subsystems are used to locate metadata for loading into global memory, and creation and deletion of objects.
