"OAK" was the IBM Mass Storage System (MSS), and was available to the public (at least to large companies who could afford it) in the mid 70s, so in that respect NSA doesn't seem to.

Bythe proposed device was code named "Comanche" and described as an online tape library to provide computer-controlled access to stored information. Numerous marketing studies and design changes were made during the early s, and finally Comanche was announced as the IBM Mass Storage System (MSS) in October The IBM Mass Storage System was an online tape library used to hold large amounts of infrequently accessed data.
It was one of the earliest examples of nearline storage. The mass storage system operates with IBM's System/ Models through running under Operating System/Virtual Storage 1 or 2 (OS/VS1 or 2) Whenever computer programming requires mass storage system functions, a new part of OS/VS -- the Mass Storage System Communicator -- will issue the appropriate commands to the mass storage control.

The IBM Mass Storage System was announced in October A combination of a new storage facility (right background) and IBM's widely used series disk subsystem (left background), the created the image of multiple magnetic disk devices -- similar to the way virtual storage used a computer's main memory as though it were much larger than it actually was.
IBM Mass storage system by CLAYTON JOHNSON IBM Corporation Boulder, Colorado SUMMARY IBM'sa hierarchical storage system, provides random access to stored data with capacity ranging from 35 X to X : Johnson, Clayton.
The IBM Mass Storage System was the monster storage device of its day. Columbia's MSS had a capacity of GB: cartridges of 50MB each; it was used to hold the entire USA Census database and make it available to users of Columbia's IBM mainframe computers.
IBM Mass Storage System IBM produced the first automated tape storage device for information in -- the Mass Storage System (MSS). Lessons learned from the MSS led to a new architecture and the first cache-control device, the IBM Model 11/13, conceived and developed in Tucson, Arizona, in The Mass Storage System—^An Overview The IBM Mass Storage System consists of IBM Disk Storage and one or two IBM Mass Storage Facilities.
The MSS provides very large data capacity, all under system control. The capaci ty range of MSS isfrom 35 billion (35 x 10^) bytes to billion ( x ) bytes (4, volumes). The IBM mass storage system is introduced. The largest storage system held 4, cartridges, stored GB, and was 20 feet long.
IBM claimed online magnetic disk storage was ten times more costly than the Released as an alternative to a manual tape reel library, the system used 4-inch long cylinders of magnetic tape that were. The IBM mass storage system is introduced.
The largest storage system held 4, cartridges, stored GB, and was 20 feet long. IBM claimed online magnetic disk storage was ten times more costly than the IBM Mass Storage System ( – ).
According to IBM, the tape was approximately 3-inches wide. The versatile device, part of the IBM Mass Storage System introduced incontained a control unit that allowed it to locate a needed cartridge and transfer it to a recording device where the information could be sent to magnetic disk drives.

From the collection, a scanned-in computer-related :: GA Mass Storage System Principles of Operation Jun The largest storage system held 4, cartridges, stored GB, and was 20 feet long. This was based off the IBM Mass Storage Systems, which was the first virtual disk system, that used disk and tape to emulate the older disk systems.
In the VTS, tape volume images would be emulated as files on a disk system, then later moved to physical tape. The IBM Photo-Digital Storage System, or PDSS, was an online archival storage system for large data was the first storage device designed from the start to hold a terabit of data ( GB).The stored data on index card sized pieces of stiff photographic film that were individually retrieved and read, and could be updated by copying data, with changes, to a new card.
Within these solution areas, System Storage hardware and software include advanced disk, tape, DVD-RAM, storage software and storage networking systems.
The IBM System Storage portfolio takes an open approach to het-erogeneous storage environments—providing ﬂexible storage solutions to help companies of all sizes.
An automated storage and retrieval system is a strategic solution to obtain a competitive advantage. Westfalia's flexible automated storage/retrieval systems (AS/RS) ensure the ability to adapt to changing market conditions now and in the future.

The parent became International Business Machines Corporation in First IBM system with virtual storage capabilities – S/ Model 65 with addition of the Dynamic Address Translation facility Mass Storage Subsystem S/ In IBM mainframe operating systems from the OS/ and successors line, a Unit Control Block (UCB) is a memory structure, or a control block, that describes any single input/output peripheral device (unit), or an exposure (alias), to the operating system.
Certain data within the UCB also instructs the Input/Output Supervisor (IOS) to use certain closed subroutines in addition to normal IOS.
