At first, Adaptec focused on devices with Parallel SCSI interfaces. Popular host bus adapters included the 154x/15xx ISA family, the 2940 PCI family, and the 29160/-320 family. Their cross-platform ASPI was an early API for accessing and integrating non- disk devices like tape drives , scanners and optical disks .
Adaptec also developed generic SCSI disk and CD-ROM drivers for DOS (ASPICD.SYS and ASPIDISK.SYS). [ 3 ] : 60–61 At least a couple of other programming interfaces for SCSI device drivers competed with ASPI in the early 1990s, including CAM (Common Access Method), developed by Apple; and Layered Device Driver Architecture, developed by Microsoft .
BusLogic, Inc. (originally BusTek, Inc.), was an American computer company active from 1988 to 1996.It specialized in the production of Small Computer System Interface (SCSI) device controller chips and controller expansion cards, becoming a dominant player in that market, behind only Adaptec.
Adaptec ACB-4000A SASI card from 1985. SCSI is derived from the Shugart Associates System Interface (SASI), [4] developed beginning 1979 [5] and publicly disclosed in 1981. [1] Larry Boucher is considered to be the "father" of SASI and ultimately SCSI due to his pioneering work first at Shugart Associates and then at Adaptec, which he founded ...
Diagrams of different Parallel SCSI symbols [1]. Parallel SCSI is not a single standard, but a suite of closely related standards. There are a dozen SCSI interface names, most with ambiguous wording (like Fast SCSI, Fast Wide SCSI, Ultra SCSI, and Ultra Wide SCSI); three SCSI standards, each of which has a collection of modular, optional features; several different connector types; and three ...
SCSI controller (Adaptec AHA-1740) Fast SCSI RAID controller (DPT PM2022) ELSA Winner 1000 Video card for ISA and EISA EISA Network card The Extended Industry Standard Architecture (frequently known by the acronym EISA and pronounced "eee-suh") is a bus standard for IBM PC compatible computers.
Some adapters cards, such as certain SCSI adapters (e.g. some made by Adaptec), were available in versions that differed only in the presence or absence of the option ROM to enable booting from attached SCSI devices. As a result of the option ROM scanning protocol, the highest-addressed option ROM is the last one to be initialized and so the ...
Fibre Channel host bus adapter. The term host bus adapter (HBA) may be used to refer to a Fibre Channel interface card. In this case, it allows devices in a Fibre Channel storage area network to communicate data between each other – it may connect a server to a switch or storage device, connect multiple storage systems, or connect multiple servers.
