G-10 DAC960PG and DAC960PJ Installation Guide

I/O

Input/Output, the transmission of information between an external source

and the computer.

I/O Bus

Any path used for the transfer of data and control information between I/O

adapters and storage controllers or storage devices. See also Bus.

Intelligent Input/Output, a driver that uses special I/O processes to eliminate

I/O bottlenecks. The processes deal with interrupt handling, buffering, and

data transfer. An I

O driver also includes an OS-specific module (OSM),

which handles higher-level OS details, and a hardware device module

(HDM), which knows how to communicate with certain devices.

ISA

Industry Standard Architecture, a standard bus (computer interconnection)

architecture associated with the IBM AT motherboard. It allows 16 bits at a

time to flow between the motherboard circuitry and an expansion slot card

and its associated device(s).

JBOD

Just A Bunch of Disks (Drives), a number of disk drives, usually in an

enclosure. JBOD implies that the disks do not use RAID technology and

function independently. All Mylex RAID controllers support JBOD mode.

Jumper

A short piece of electrical conductor encased in plastic used to connect pins

on a device to provide settings that the user can change. The settings remain

constant during operation. For example, jumpers often set SCSI ID,

termination, and IDE master/slave settings.

Kilobyte

(1,024). Abbreviated as K or KB.

Logical Drive

The logical devices presented to the operating system. System drives are

presented as available disk drives, each with a capacity specified by the

Mylex RAID controller.
