S - Definitions

  • S

    SAN file system

    A SAN file system (that is, a storage area network file system) is programming that enables the sharing of the same copies of files stored on common storage media among multiple servers that may have different operating systems.

  • SAN island

    A SAN island is a storage area network (SAN) that exists as a discrete, isolated entity within a larger SAN. The components of a SAN island are usually all located in the same building, or even within a single room.

  • SAN routing

    SAN (storage area network) routing is a technology used for interconnecting SAN islands (separately designated logical portions of a storage area network) within a larger network.

  • SAN switch (storage area network switch)

    A storage area network (SAN) switch is a device that connects servers and shared pools of storage devices and is dedicated to moving storage traffic.

  • SAN-in-a-box

    A SAN-in-a-box, also known as a SAN-in-a-can or a SAN kit, is a data storage device that includes all the basic SAN components are in a single package.

  • SAS SSD (Serial-Attached SCSI solid-state drive)

    A SAS solid-state drive (SSD) is a NAND flash-based storage or caching device that uses the serial-attached SCSI (SAS) interface to connect to the host computer and fits into the same slot as a hard disk drive (HDD).

  • SATA controller

    A SATA controller handles how hard drives are connected to a computer's motherboard.

  • SATA Express (SATAe)

    SATA Express (SATAe or Serial ATA Express) is a bus interface to connect storage devices to a computer motherboard, supporting SATA and PCI Express protocols simultaneously.

  • SCSI (Small Computer System Interface)

    Definition: The Small Computer System Interface (SCSI) is a set of parallel interface standards used to attach disk drives and other peripherals to a computer.

  • SCSI controller (Small Computer System Interface controller)

    A SCSI controller, also called a host bus adapter (HBA), is a card or chip that allows a SCSI storage device to communicate with the operating system across a SCSI bus.

  • secondary storage

    Secondary storage is used to protect inactive data written from a primary storage array to a nonvolatile tier of disk, flash or tape.

  • sector

    On a computer diskette or hard disk, a sector is one of the "pie slices" the diskette or disk is divided into.

  • Secure Digital card (SD card)

    SD cards use flash memory to provide nonvolatile storage. They are more rugged than traditional storage media and are used in more portable storage media.

  • self-service cloud computing

    Self-service cloud computing is a form of private cloud service where the customer provisions storage and launches applications without going through an external cloud service provider.

  • semiconductor fab

    A semiconductor fab is a manufacturing plant in which raw silicon wafers are turned into integrated circuits.
