Ethernet Support Guide for HP-UX 11i v3

IEEE 802.3u-1995
network
The 802.3 committee that produced the standard for LAN networks.
Integrated
FlexFabric adapter
An I/O card built into the system board that supports both LAN and FCoE functionality on the
same ports. It supports LAN and FCoE or accelerated iSCSI connectivity concurrently with
high-performance protocol offloads that optimize server efficiency and maximize server
virtualization ratios. Integrated FlexFabric adapters provide more functionality and intelligence
than do LOMs. The integrated FlexFabric adapter technology helps enable the HP Converged
Infrastructure model and ubiquity of both 10GbE and network convergence. An Integrated
FlexFabric adapter. Also known as a Converged Network Controller (CNC), Converged Network
Integrated Controller (CNIC), or converged LOM.
Internet An internetwork, a global system of interconnected computer networks that use the standard
Internet protocol suite to serve billions of users worldwide. A network of networks that consists of
millions of private, public, academic, business, and government networks, of local to global
scope, that are linked by a broad array of electronic, wireless, and optical networking
technologies.
Internet address The network address of a computer node. This address identifies both which network the host is
on and which host it is. For more information, see the HP-UX IP Address and Client Management

interrupt
coalescing
To avoid flooding the host system with too many interrupts, packets are collected and one single
interrupt is generated for multiple packets instead of generating interrupts for every single packet.
Adapters provide various degrees of control of interrupt coalescing behavior.
intranet A computer network that uses IP technology to share information, operating systems, or computing
services within an organization or corporation. Sometimes the term refers only to an organization’s
internal website, but may be a more extensive part of the organization’s information technology
infrastructure and may consist of multiple LANs.
IP Internet Protocol. Data travels over an IP-based network in the form of packets.
IP address See Internet address.
iSCSI Internet SCSI. An IP-based storage networking standard for linking data storage facilities. Facilitates
data transfers over intranets and can manage storage over long distances. Can be used to transmit
data over LANs, WANs, or the Internet.
See also SCSI.
Jumbo Frames Ethernet frames with more than 1500 bytes of payload or maximum transmission unit (MTU) size;
generally, 9000 bytes. The size that optimizes bulk data transfers: larger amounts of data can
be sent with greater efficiency.
LAN See local area network (LAN).
LAN on
Motherboard
(LOM)
A chip or chipset capable of network connections that has been embedded directly on the
motherboard of a server. For example, server blades include LOMs that are dual-port 1 or 10
Gigabit Ethernet interfaces.
LAN provider A software module that you can use to find and collect information about the Ethernet links on a
system. It is based on the CIM (Common Information Model) standard from the distributed
management task force (DMTF).
link level In the hierarchical structure of a primary or secondary station, the conceptual level of control or
data processing logic that controls the data link.
local area network
(LAN)
A data communications system that allows a number of independent devices to communicate
with each other.
local network The network to which a node is directly attached.
Major Number Unique value that identifies an individual hardware device.
maximum
transmission unit
(MTU)
Largest amount of data that can be transmitted through the interface. This value does not include
the LLC or MAC headers.
Mbit/s Megabits per second; also referred to as Mb/s.
