  2. IOPS - Wikipedia

    en.wikipedia.org/wiki/IOPS

    Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).

  3. I/O scheduling - Wikipedia

    en.wikipedia.org/wiki/I/O_scheduling

    Input/output (I/O) scheduling is the method that computer operating systems use to decide in which order I/O operations will be submitted to storage volumes. I/O scheduling is sometimes called disk scheduling .

  4. iostat - Wikipedia

    en.wikipedia.org/wiki/Iostat

    iostat (input/output statistics) is a computer system monitor tool used to collect and show operating system storage input and output statistics. It is often used to identify performance issues with storage devices, including local disks, or remote disks accessed over network file systems such as NFS.

  5. Hard disk drive - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive

    A hard disk drive (HDD), hard disk, hard drive, or fixed disk [a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.

  6. Anticipatory scheduling - Wikipedia

    en.wikipedia.org/wiki/Anticipatory_scheduling

    Anticipatory scheduling is an algorithm for scheduling hard disk input/output (I/O scheduling). It seeks to increase the efficiency of disk utilization by "anticipating" future synchronous read operations.

    input/output (I/O) The communication between an information processing system (such as a computer), and the outside world. Input/Output Operations Per Second (IOPS) A common performance measurement used to benchmark computer storage devices like hard disk drives. instruction

  8. SGPIO - Wikipedia

    en.wikipedia.org/wiki/SGPIO

    Of the four signals, three are driven by the HBA and one by the backplane. Typically, the HBA is a storage controller located inside a server, desktop, rack or workstation computer that interfaces with hard disk drives or solid-state drives to store and retrieve data. It is considered an extension of the general-purpose input/output (GPIO

  9. Input/output - Wikipedia

    en.wikipedia.org/wiki/Input/output

    The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.
