StorageTek Tape Formats
Storage Technology Corporation (marketing as 'StorageTek' ne word created several magnetic tape data storage formats. These are commonly used with large computer systems, typically in conjunction with a robotic tape library. The most recent format is the T10000. StorageTek primarily competed with IBM in this market, and continued to do so after its acquisition by Sun Microsystems in 2005 and as part of the Sun Microsystems acquisition by Oracle in 2009. Cartridge formats Most (but not all) modern tape cartridges are format tape, first popularized by the IBM 3480 and DEC DLT formats. This is a small, rectangular and easily handled tape cartridge compared to the previously common 7-track and 9-track round tape reels. This form factor has proven to work well with stand alone drives and for use in automated tape libraries. Nearly all " tape formats today are a single hub design, whereby the tape is wound onto a single hub, entirely within the external shell and presents one en ...

Storage Technology Corporation
Storage Technology Corporation (StorageTek or STK, earlier STC) was a data storage technology company headquartered in Louisville, Colorado. New products include data retention systems, which it calls "information lifecycle management" (ILM). Its remaining product line is now part of Oracle Corporation, and marketed as Oracle StorageTek, with a focus on tape backup equipment and software to manage storage systems. History In 1969 four former IBM engineers— Jesse Aweida, Juan Rodriguez, Thomas S. Kavanagh, and Zoltan Herger—founded the Storage Technology Corporation. The headquarters was in Louisville, Boulder County, Colorado. In the 1970s, StorageTek launched its Disk Products division. After a failed attempt to develop an IBM-compatible mainframe, and an optical disk product line, the company filed for Chapter 11 bankruptcy protection in 1984. Starting in 1987, new management invested in an automated tape library product line that "picked" tapes from a silo-like contr ...

Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. Standards bodies have deprecated this binary usage of the mega- prefix in favor of a new set of binary prefixes, by means of which the quantity 220 B is named mebibyte (symbol MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte m ...

D3 Video
D-3 is an uncompressed composite digital video format invented at NHK and introduced commercially by Panasonic. It was launched in 1991 to compete with Ampex's D-2. Overview D-3 uses half-inch metal particle tape at 83.88 mm/s (compare to D-2's 19 mm and 131.7 mm/s). Like D-2, the composite video signal is sampled at four times the color subcarrier frequency, with eight bits per sample. Four channels of 48 kHz 16–20 bit PCM audio, and other ancillary data, are inserted during the vertical blanking interval. The aggregate net (error corrected) bitrate of the format is 143 Mbit/s, and because the codec is lossless, it has been used in data applications. Camcorders were available which used this format, and are to date the only digital tape camcorders to use a lossless encoding scheme. The D-5 digital component video format, introduced in 1993 by Panasonic, uses the D-3 transport and tape running at roughly double D-3 speed. The D-3 transport in turn ...

SCSI
Small Computer System Interface (SCSI, ) is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives. SCSI was introduced in the 1980s and has seen widespread use on servers and high-end workstations, with new SCSI standards being published as recently as SAS-4 in 2017. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the presence of "unknown" as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements. The initial Parallel SCSI was most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and optical disc drives, although not all controllers can handle ...

Fibre Channel
Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. Fibre Channel is primarily used to connect computer data storage to Server (computing), servers in storage area networks (SAN) in commercial data centers. Fibre Channel networks form a switched fabric because the switches in a network operate in unison as one big switch. Fibre Channel typically runs on optical fiber cables within and between data centers, but can also run on copper cabling. Supported data rates include 1, 2, 4, 8, 16, 32, 64, and 128 gigabit per second resulting from improvements in successive technology generations. The industry now notates this as Gigabit Fibre Channel (GFC). There are various upper-level protocols for Fibre Channel, including two for block storage. Fibre Channel Protocol (FCP) is a protocol that transports Small Computer System Interface, SCSI commands over Fibre Channel networks. FICON is a protocol that transports ESCON comman ...

FICON
FICON (Fibre Connection) is the IBM proprietary name for the ANSI ''FC-SB-3 Single-Byte Command Code Sets-3 Mapping Protocol'' for Fibre Channel (FC) protocol. It is a FC layer 4 protocol used to map both IBM's antecedent (either ESCON or parallel Bus and Tag) channel-to-control-unit cabling infrastructure and protocol onto standard FC services and infrastructure. The topology is fabric utilizing FC switches or directors. Valid rates include 1, 2, 4, 8, 16, and 32 Gigabit per second data rates at distances up to 100 km. FICON was introduced in 1998 as part of System/390 G5 IBM mainframe. In July 2013, FICON replaced ESCON in new zEnterprise BC12/EC12, and later models, because of FICON's technical superiority (especially its higher performance) and lower cost. Protocol internals Each FICON channel port is capable of multiple concurrent data exchanges (a maximum of 32) in full duplex mode. Information for active exchanges is transferred in Fibre Channel sequences ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

ESCON
ESCON (Enterprise Systems Connection) is a data connection created by IBM, and is commonly used to connect their mainframe computer A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise ...s to peripheral devices such as disk storage, tape drives and IBM 3270 display controllers. ESCON is an optical fiber, half-duplex, Serial communications, serial interface. It originally operated at a rate of 10MB/s, which was later increased to 17MB/s. The current maximum distance is 43 kilometers. IBM introduced ESCON in September 1990 as part of its System/390 announcement. It replaced the older, slower (4.5MB/s), copper-based, parallel, IBM System/360 Bus and Tag channels technology of 1960-1990 era mainframes. Optical fiber is smaller in diameter and weight, and hence could save installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Gigabyte
The gigabyte () is a multiple of the unit byte for digital information. The SI prefix, prefix ''giga-, giga'' means 109 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard disk drive, hard drives, solid-state drives, and magnetic-tape data storage, tapes, as well as data transmission speeds. The term is also used in some fields of computer science and information technology to denote (10243 or 230) bytes, however, particularly for sizes of random-access memory, RAM. Thus, some usage of ''gigabyte'' has been ambiguous. To resolve this difficulty, IEC 80000-13 clarifies that a ''gigabyte'' (GB) is 109 bytes and specifies the term ''gibibyte'' (GiB) to denote 230 bytes. These differences are still readily seen, for example, when a 400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Magnetic Tape Data Storage
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track, later 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloaders and tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage is now used more for system backup, data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive. Open reels Initially, magnetic tape for data storage was wound on reels. This standard for large computer systems persisted through the late 1980s, with steadily increasing capacity d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Linear Tape-Open
Linear Tape-Open (LTO), also known as the LTO Ultrium format, is a magnetic tape data storage technology used for backup, data archiving, and data transfer. It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time. Upon introduction, LTO rapidly defined the ''super tape'' market segment and has consistently been the best-selling super tape format. The latest generation as of 2025, LTO-10, can hold in one cartridge, or with industry-standard 2.5:1 compression. Cartridges contain hundreds of meters of half-inch (12.65 mm) wide tape media wound onto a single reel. Mechanisms (a.k.a. tape drives, streamers) extract the tape from the cartridge and spool it up on a second reel in the mechanism, reading or writing data as the tape moves between reels. Robotic Tape library, libraries exist that can hold hundreds or thousands of LTO cartridges and dozens of mechanisms. The original version of LTO U ...
