Abstract:
A tape library is seldom considered as a viable place for
constructing a file system for a sequential write/read device.
Storage virtualization technology has become a buzzword in
technology circles lately, in this paper we propose a tape library
file system, called TLFS. The purpose of TLFS is to maintain a
consistent view of mass storage so that the user can effectively
manage it. Like disk file system, TLFS provides some file system
operations, such as create, delete, open, close, read and write
files/directories. It supports remote data access, backup,
mirroring, replication by iSCSI protocol and facilitates fast data
backup and archive. Moreover, TLFS supports large-scale storage
management, provides file system fragment management, defenses virus
and has transparent file movement. The prototype system, which is
built by a SCSI disk and a tape library, is present and some
implementation details are shown. Also, the experiment results are
analyzed.
