Each of the five LSMs contains approximately 6000 cartridges (1/2-in, 18-track) with a robot performing cartridge mounts and dismounts. Multiple LSMs can be connected together in such a way that cartridges are passed between robots for improved optimization of cartridge transports. The current configuration has eight 4480 cartridge transports attached to each of the five LSMs for a total of forty transports. With five LSMs installed, the current storage capacity is very close to six terabytes (TB). A discussion is presented of the original decision-making process, the implementation planning process, the implementation of both the StorageTek 4480 transports and 4400 Automatic Cartridge System, and some critical observations from a heavy production user of this type of mass storage device.<<ETX>>","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

He concludes that basic tape and machine technology to increase capacity and bandwidth with 64-fold to 43 TB and one GB/s has been demonstrated piecemeal.

Key requirements are that the medium be consistent at all times and that large amounts of storage are not wasted in maintaining the directory information appropriate to a normal read/write file system. The file system is implemented in four layers. The first layer replaces the fixed sector-size characteristic of the medium with separate data and control streams composed of variable-length tagged records. The second layer defines data structures used by the control stream: file headers, a series of unmount records, and a journal of directory updates which are pending. The third layer implements a generalized file system (directories, etc.) containing common features of the four target systems: MS-DOS, Unix, VAX/VMS and Macintosh. The fourth layer is the operating system-specific adapter. The objective is to provide a common on-disk structure for all of these systems, while implementing the equivalent of a fully erasable file system. Efficiency of storage space usage and of file reading and writing time are equally important.<<ETX>>","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.
