servers and all I/O modules, multiplexes
the keyboard/video/mouse (KVM), and
monitors critical information about the
chassis and blade servers.
management server
The server on which IBM Director Server
is installed.
master system
In z/VM Center, an operating system
instance that has been set up to serve
Virtual Server Deployment as a model for
creating operating system templates.
media access control (MAC) address
In a local area network, the protocol that
determines which device has access to the
transmission medium at a given time.
minidisk
A direct access storage device (DASD) or
a logical subdivision of a DASD that has
its own virtual device number.
N
nonvolatile random-access memory (NVRAM)
Random access memory (storage) that
retains its contents after the electrical
power to the machine is shut off.
notification
See alert.
NVRAM
See nonvolatile random-access memory.
O
operating system instance
An individual realization of an operating
system with a particular version,
configuration, physical location, and
identifier.
operating system template
A set of installation and configuration
data that z/VM Center uses as a source
for creating operating system instances.
Operating system templates are created
from master systems.
out-of-band communication
Communication that occurs through a
modem or other asynchronous
connection, for example, service processor
alerts sent through a modem or over a
LAN. In an IBM Director environment,
such communication is independent of
the operating system and interprocess
communication (IPC).
P
partition
See scalable partition.
PCI See Peripheral Component Interconnect.
PCI-X See Peripheral Component Interconnect-X.
Peripheral Component Interconnect (PCI)
A standard for connecting attached
devices to a computer.
Peripheral Component Interconnect-X (PCI-X)
An enhancement to the Peripheral
Component Interconnect (PCI)
architecture. PCI-X enhances the
Peripheral Component Interconnect (PCI)
standard by doubling the throughput
capability and providing additional
adapter-performance options while
maintaining backward compatibility with
PCI adapters.
PFA See Predictive Failure Analysis
®
.
physical platform
An IBM Director managed object that
represents a single physical chassis or
server that has been discovered through
the use of the Service Location Protocol
(SLP).
plug-in
A software module, often written by a
third party, that adds function to an
existing program or application such as a
Web browser. See IBM Director extension.
POST See power-on self-test.
power-on self-test
A series of internal diagnostic tests
activated each time the system power is
turned on.
Predictive Failure Analysis (PFA)
A scheduled evaluation of system data
that detects and signals parametric
degradation that might lead to functional
failures.
private key
1) In secure communication, an
algorithmic pattern used to encrypt
messages that only the corresponding
public key can decrypt. The private key is
also used to decrypt messages that were
encrypted by the corresponding public
