Installation Guide
CMCV: Corrected Memory Check Vector.
CMOS: Complementary Metal Oxide Semiconductor.
A type of low-power integrated circuits. System
startup parameters are stored in CMOS memory.
They can be changed via the system setup utility.
COM: Component Object Model. Microsoft
technology for component based application
development under Windows.
COM +: Component Object Model +. Microsoft
technology for component based application
development under Windows. The external part of
the PAM software package is a COM+ application.
COM1 or COM2: The name assigned to a serial
port to set or change its address. See Serial Port.
Command: An instruction that directs the computer
to perform a specific operation.
Configuration: The way in which a computer is set
up to operate. Configurable options include CPU
speed, serial port designation, memory allocation,
...
Configuration Tasks: A PAM feature used to
configure and customize the server.
Control Pane: One of the three areas of the PAM
web page. When an item is selected in the PAM
Tree pane, details and related commands are
displayed in the Control pane. See PAM Tree pane
and Status pane.
Core Unit: A main CSS module unit interconnecting
the MIO, MQB, MSX and MFL boards. See MIO,
MQB, MSX, MFL.
COS: Cluster Operating System.
CPE: Corrected Platform Error.
CPEI: Corrected Platform Error Interrupt.
CPU: Central Processing Unit. See Microprocessor
and Socket.
CSE: Customer Service Engineer.
CSS: Central Sub-System. See CellBlock.
CSS Module: A MidPlane with all its connected
components (QBBs, IO boards, PMB) and utility
devices. See Module.
D
D2D: DC to DC converter.
DC: Direct Current generated by the power supply.
See AC.
Default Setting: The factory setting your server uses
unless instructed otherwise.
Density: The capacity of information (bytes) that can
be packed into a storage device.
Device Driver: A software program used by a
computer to recognize and operate hardware.
DIB: Device Interface Board. The DIB provides the
necessary electronics for the Internal Peripheral
Drawer. See IPD and Chained DIBs.
DIG64: Developer Interface Guide for IA64.
DIM Code: Device Initialization Manager. Initializes
different BUSes during the BIOS POST.
DIMM: Dual In-line Memory Module - the smallest
system memory component.
Disk Drive: A device that stores data on a hard or
floppy disk. A floppy disk drive requires a floppy
disk to be inserted. A hard disk drive has a
permanently encased hard disk.
DMA: Direct Memory Access. Allows data to be
sent directly from a component (e.g. disk drive) to
the memory on the motherboard). The
microprocessor does not take part in data transfer
enhanced system performance.
DMI: Desktop Management Interface. An industry
framework for managing and keeping track of
hardware and software components in a system of
personal computers from a central location.
DNS: Domain Name Server. A server that retains
the addresses and routing information for TCP/IP
LAN users.
Domain: is the coherent set of resources allocated to
run a customer activity, i.e. the association -at boot
time- of a Partition, an OS instance (including
applications) and associated LUNs and an
execution context including execution modes and
persistent information (e.g. time, date of the OS
instance). Domain definitions and initializations are
performed via PAM. A Domain can be modified to
run the same OS instance on a different Partition.
When a Domain is running, its resources are
neither visible nor accessible to other running
Domains.
Domain Identity: a PAM Domain management
logical resource. This resource contains context
information related to the Customer activity running
in a domain. The most visible attribute of this
resource is the name that the Customer gives to the
activity. For each domain created, the Domain
management feature allows the operator to define a
new activity or choose an activity from the list of
existing activities. See Domain.
Domain Manager: A PAM feature used to power
on / off and manage server domains. See Domain.
DPS: Distributed Power Supply.
