Sun Microsystems X4150 manual Advanced Programmable Interrupt Controller, Advanced Technology

CPU in response to system load, thus enabling the system’s main power- consuming element (the CPU) to vary its power consumption based on system load.

Interrupt Controller

(APIC) A device that manages interrupt requests for multiple central processing units (CPUs). The APIC decides which request has the highest priority and sends an interrupt to the processor for that request.

Advanced Technology

Attachment (ATA) A specification that describes the physical, transport, electrical, and command

protocols used to attach storage devices to host systems.

Advanced Technology

Attachment Packet

Interface (ATAPI) An extension to the Advanced Technology Attachment (ATA) standard for connecting removable media storage devices in host systems, including CD/DVD drives, tape drives, and high-capacity diskette drives. Also called “ATA-2” or “ATA/ATAPI.”

agent A software process, usually corresponding to a particular local managed host, that carries out manager requests and makes local system and application information available to remote users.

alert A message or log generated by the collection and analysis of error events. An alert indicates that there is a need to perform some hardware or software corrective action.

Alert Standard Format

(ASF) A preboot or out-of-band platform management specification that enables a device, such as an intelligent Ethernet controller, to autonomously scan ASF- compliant sensors on the motherboard for voltage, temperature, or other excursions and to send Remote Management and Control Protocol (RMCP) alerts according to the platform event trap (PET) specification. ASF was intended primarily for out-of-band management functions for client desktops. ASF is defined by the Distributed Management Task Force (DMTF).

authentication The process that verifies the identity of a user in a communication session, or a device or other entity in a computer system, before that user, device, or other entity can access system resources. Session authentication can work in two directions. A server authenticates a client to make access control decisions. The client can authenticate the server as well. With Secure Sockets Layer (SSL), the client always authenticates the server.

authorization The process of granting specific access privileges to a user. Authorization is based on authentication and access control.

AutoYaST An installation program for SUSE Linux that automates the process of configuring one or more servers.
