Host Adapter
In computer hardware a host controller, host adapter or host bus adapter (HBA) connects a computer system bus which acts as the host system to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, SAS, NVMe, Fibre Channel and SATA devices. Devices for connecting to FireWire, USB and other devices may also be called host controllers or host adapters. Host adapters can be integrated in the motherboard or be on a separate expansion card. The term network interface controller (NIC) is more often used for devices connecting to computer networks, while the term converged network adapter can be applied when protocols such as iSCSI or Fibre Channel over Ethernet allow storage and network functionality over the same physical connection. SCSI A connects a host system and a peripheral SCSI device or storage system. These adapters manage service and task communication between the host and target. Typically a device driver, linked to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibre Channel Over Ethernet
Fibre Channel over Ethernet (FCoE) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol. The specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard published in 2009. FCoE did not see widespread adoption. Functionality FCoE transports Fibre Channel directly over Ethernet while being independent of the Ethernet forwarding scheme. The FCoE protocol specification replaces the FC0 and FC1 layers of the Fibre Channel stack with Ethernet. By retaining the native Fibre Channel constructs, FCoE was meant to integrate with existing Fibre Channel networks and management software. Traditionally, data centers used both Ethernet for TCP/IP networks and Fibre Channel for SANs, each having different and mostly incompatible interfaces/connections and interconnects/wiri ...

SBus
SBus is a computer bus system that was used in most SPARC-based computers (including all SPARCstations) from Sun Microsystems and others during the 1990s. It was introduced by Sun in 1989 to be a high-speed bus counterpart to their high-speed SPARC processors, replacing the earlier (and by this time, outdated) VMEbus used in their Motorola 68020- and 68030-based systems and early SPARC boxes. When Sun moved to open the SPARC definition in the early 1990s, SBus was likewise standardized and became IEEE-1496. In 1997 Sun started to migrate away from SBus to the Peripheral Component Interconnect (PCI) bus, and today SBus is no longer used. The industry's first third-party SBus cards were announced in 1989 by Antares Microsystems; these were a 10BASE2 Ethernet controller, a SCSI-SNS host adapter, a parallel port, and an 8-channel serial controller. The specification was published by Edward H. Frank and James D. Lyle. A technical guide to the bus was published in 1992 in book fo ...

Peripheral Component Interconnect
Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor's address space. It is a parallel bus, synchronous to a single bus clock. Attached devices can take either the form of an integrated circuit fitted onto the motherboard (called a ''planar device'' in the PCI specification) or an expansion card that fits into a slot. The PCI Local Bus was first implemented in IBM PC compatibles, where it displaced the combination of several slow Industry Standard Architecture (ISA) slots and one fast VESA Local Bus (VLB) slot as the bus configuration. It has subsequently been adopted for other computer types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open System (computing)
Open systems are computer systems that provide some combination of interoperability, software portability, portability, and open standard, open software standards. (It can also refer to specific installations that are configured to allow unrestricted access by people and/or other computers; this article does not discuss that meaning). The term was popularized in the early 1980s, mainly to describe systems based on Unix, especially in contrast to the more entrenched mainframe computer, mainframes and minicomputers in use at that time. Unlike older legacy systems, the newer generation of Unix systems featured standardized programming interfaces and peripheral interconnects; third party development of hardware and software was encouraged, a significant departure from the norm of the time, which saw companies such as Amdahl Corporation, Amdahl and Hitachi Data Systems History, Hitachi going to court for the right to sell systems and peripherals that were compatible with IBM's mainframe ...

Storage Area Network
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block device, block-level data storage. SANs are primarily used to access Computer data storage, data storage devices, such as disk arrays and tape libraries from Server (computing), servers so that the devices appear to the operating system as direct-attached storage. A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN). Although a SAN provides only block-level access, file systems built on top of SANs do provide file-level access and are known as shared-disk file systems. Newer SAN configurations enable hybrid SAN and allow traditional block storage that appears as local storage but also object storage for web services through APIs. Storage architectures Storage area networks (SANs) are sometimes referred to as ''network behind the servers'' and historically developed out of a centralized data storage mode ...

LSI Corporation
LSI Logic Corporation was an American company founded in Santa Clara, California, was a pioneer in the ASIC and EDA industries. It evolved over time to design and sell semiconductors and software that accelerated storage and networking in data centers, mobile networks and client computing. In April 2007, LSI Logic merged with Agere Systems and rebranded the firm as LSI Corporation. On May 6, 2014, LSI Corporation was acquired by Avago Technologies (now known as Broadcom Inc.) for $6.6 billion. History 1981–2004 LSI Logic Corporation was incorporated in November 1980 by Wilfred J. Corrigan and began operating in early 1981 using leased facilities in Santa Clara, California. The name "LSI" referred to Large Scale Integration. Corrigan recruited co-founders Bill O'Meara (VP Marketing and Sales), Rob Walker (VP Engineering) and Mitchell "Mick" Bohn (CFO) as co-founders. Initial funding of $6 million came from a consortium of venture capitalists, including Kleiner Per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptec
Adaptec, Inc., was a computer storage company and remains a brand for computer storage products. The company was an independent firm from 1981 to 2010, at which point it was acquired by PMC-Sierra, which itself was later acquired by Microsemi, which itself was later acquired by Microchip Technology. History Larry Boucher, Wayne Higashi, and Bernard Nieman founded Adaptec in 1981. 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. With advancements in technology, RAID functions were added while interfaces evolved to PCIe and SAS. Adaptec made a number of acquisitions in the 1990s to expand their reach in the SCSI peripheral market. In March 1993, they acquired Trantor Systems Ltd. of Fremont, California, for $ ...

SCSI Initiator
In computer data storage, a SCSI initiator is the endpoint that initiates a SCSI session, that is, sends a SCSI command. The initiator usually does not provide any Logical Unit Numbers (LUNs). On the other hand, a SCSI target is the endpoint that does ''not'' initiate sessions, but instead waits for initiators' commands and provides required input/output data transfers. The target usually provides to the initiators one or more LUNs, because otherwise no read or write command would be possible. Detailed information Typically, a computer is an initiator and a data storage device is a target. As in a client–server architecture, an initiator is analogous to the client, and a target is analogous to the server. Each SCSI address (each identifier on a SCSI bus) displays behavior of initiator, target, or (rarely) both at the same time. There is nothing in the SCSI protocol that prevents an initiator from acting as a target or vice versa. SCSI initiators are sometimes wrongly calle ...
