  • Deleting an object from an object storage subsystem for managing paged metadata
    Patent number: 11269544
    Abstract: A storage array uses paged metadata. Each storage director has access to a plurality of object storage systems which describe locations of paged metadata in backing storage. Each object storage system includes different types of inodes which describe objects in backing storage. The object storage systems are used to locate and relocate metadata for loading into global memory, and creation and deletion of objects. An object storage system may be selected based on factors including ratio of different inode types, locality of object usage and anticipated object activity level.

  • Object storage subsystems
    Patent number: 11010101
    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.
