OPENSTACK SWIFT INTERFACE FOR TAPE LIBRARY (OSSITL)

摘要

A system for providing a Swift Storage Node includes a media library having drives and tapes formatted according to a Linear Tape File System (LTFS). A management system is connected over a first interface to the media library and over a second interface to a Swift Proxy Server. The management system provides a Swift-On-Disk File System Application Programming Interface (API) over the second external interface, uses a Virtual File System (VFS), stores and registers objects in the VFS, controls the media library to move a respective tape into a respective drive, moves the object from the cache data store to the respective tape using the LTFS and updates the VFS. The management system also receives a request over the Swift-On-Disk File System API to read an object, determines in the VFS the location of the object, loads the object using the LTFS and provides the object.
