HP Integrity iLO 3 Operations Guide

D
DDNS Dynamic Domain Name System. DDNS is how iLO 3 automatically registers its name with the
Domain Name System so that when iLO 3 receives its new IP address from DHCP, users can
connect to the new iLO 3 using the host name, rather than the new IP address.
DHCP Dynamic Host Configuration Protocol. A protocol that enables a DHCP server to assign Internet
Protocol (IP) addresses dynamically to systems on a Transmission Control Protocol/Internet Protocol
(TCP/IP) network. Without DHCP, IP addresses must be entered manually at each computer, and
when computers are moved to another location on another part of the network, a new IP address
must be entered.
directory server In the Lightweight Directory Access Protocol (LDAP), a server which stores and provides information
about people and resources within an organization from a logically centralized location.
distinguished
name (DN)
In the Lightweight Directory Access Protocol (LDAP), a unique text string that identifies an entry's
name and location within the directory. A DN can be a fully qualified domain name (FQDN)
that includes the complete path from the root of the tree.
DNS Domain Name Server. The server that typically manages host names in a domain. DNS servers
translate host names, such as www.example.com, into Internet Protocol (IP) addresses, such as
030.120.000.168.
Domain Name Service. The data query service that searches domains until a specified host name
is found.
Domain Name System. A distributed, name resolution system that enables computers to locate
other computers on a network or the Internet by domain name. The system associates standard
Internet Protocol (IP) addresses, such as 00.120.000.168, with host names, such as
www.hp.com. Machines typically acquire this information from a DNS server.
domain A grouping of hosts that is identified by a name. The hosts usually belong to the same Internet
Protocol (IP) network address.
domain name The unique name assigned to a system or group of systems on the Internet. The host names of all
the systems in the group have the same domain name suffix. Domain names are interpreted from
right to left.
E
ethernet An industry-standard type of local area network (LAN) that enables real-time communication
between systems connected directly through cables. Ethernet uses a Carrier Sense Multiple
Access/Collision Detection (CSMA/CD) algorithm as its access method, which all nodes listen
for, and any node can begin transmitting data. If multiple nodes attempt to transmit at the same
time (a collision), the transmitting nodes wait for a random time before attempting to transmit
again.
event A change in the state of a managed object. The event-handling subsystem can provide a
notification, to which a software system must respond when it occurs, but which the software did
not solicit or control.
extended schema A platform-specific schema derived from the common model. An example is the Win32 schema.
F
firmware Software that is typically used to help with the initial booting stage of a system and with system
management. Firmware is embedded in read-only memory (ROM) or programmable ROM (PROM).
FPGA Field Programmable Gate Array. A semiconductor device containing programmable logic
components and programmable interconnects.
FTP File Transfer Protocol. A basic Internet protocol based on Transmission Control Protocol/Internet
Protocol (TCP/IP) that enables the retrieving and storing of files between systems on the Internet
without regard for the operating systems or architectures of the systems involved in the file transfer.
