HP Workgroup System AWSXCIG-1A manual Nat

MySQL	A relational database system developed by MySQL AB that is used in HP XC systems to store
	and track system configuration information.
N
NAT	Network Address Translation. A mechanism that provides a mapping (or transformation) of
	addresses from one network to another. This enables external access of a machine on one LAN
	that has the same IP address as a machine on another LAN, by mapping the LAN address of
	the two machines to different external IP addresses.
Network Address	See NAT.
Translation
Network	See NIS.
Information
Services
NIS	Network Information Services. A mechanism that enables centralization of common data that
	is pertinent across multiple machines in a network. The data is collected in a domain, within
	which it is accessible and relevant. The most common use of NIS is to maintain user account
	information across a set of networked hosts.
NIS client	Any system that queries NIS servers for NIS database information. Clients do not store and
	maintain copies of the NIS maps locally for their domain.
NIS master server	A system that stores the master copy of the NIS database files, or maps, for the domain in the
	/var/yp/DOMAIN directory and propagates them at regular intervals to the slave servers. Only
	the master maps can be modified. Each domain can have only one master server.
NIS slave server	A system that obtains and stores copies of the master server's NIS maps. These maps are updated
	periodically over the network. If the master server is unavailable, the slave servers continue to
	make the NIS maps available to client systems. Each domain can have multiple slave servers
	distributed throughout the network.
O
OA	The enclosure management hardware, software, and firmware that is used to support all of the
	managed devices contained within the HP BladeSystem c-Class enclosure.
onboard	See OA.
administrator
P
parallel	An application that uses a distributed programming model and can run on multiple processors.
application	An HP XC MPI application is a parallel application. That is, all interprocessor communication
	within an HP XC parallel application is performed through calls to the MPI message passing
	library.
PXE	Preboot Execution Environment. A standard client/server interface that enables networked
	computers that are not yet installed with an operating system to be configured and booted
	remotely. PXE booting is configured at the BIOS level.
R
resource	Nodes with this role manage the allocation of resources to user applications.
management role
role	A set of services that are assigned to a node.
Root	A component of the administration network. The top switch in the administration network; it
Administration	may be a logical network switch comprised of multiple hardware switches. The Root Console
Switch	Switch is connected to the Root Administration Switch.
root node	A node within an HP XC system that is connected directly to the Root Administration Switch.
