enhanced transmission selection (ETS)
A standard that specifies the enhancement
of transmission selection to support the
allocation of bandwidth among traffic
classes. When the offered load in a traffic
class does not use its allocated bandwidth,
enhanced transmission selection allows
other traffic classes to use the available
bandwidth. The bandwidth- allocation
priorities coexist with strict priorities. ETS
includes managed objects to support
bandwidth allocation. The per traffic class
ETS minimum bandwidth mode pre-empts
the per partition minimum TX bandwidth
settings. For more information, refer to

Ethernet
The most widely used LAN technology that
transmits information between computers,
typically at speeds of 10Mbps to 100Gbps.
extensible firmware interface (EFI)
A specification that defines a software
interface between an operating system
and platform firmware. EFI is a replace-
ment for the older BIOS firmware interface
present in all IBM PC-compatible personal
computers.
file transfer protocol (FTP)
A standard network protocol used to
transfer files from one host to another host
over a TCP-based network, such as the
Internet. FTP is required for out-of-band
firmware uploads that will complete faster
than in-band firmware uploads.
human interface infrastructure (HII)
A specification (part of UEFI 2.1) for
managing user input, localized strings,
fonts, and forms, that allows OEMs to
develop graphical interfaces for preboot
configuration.
Institute of Electrical and Electronics
Engineers (IEEE)
An international nonprofit organization for
the advancement of technology related to
electricity.
maximum transmission unit (MTU)
Refers to the size (in bytes) of the largest
packet (IP datagram) that a specific layer
of a communications protocol can transfer.
message signaled interrupts (MSI)
Two PCI-defined extensions to support
message signaled interrupts (MSI), in PCI
2.2 and later and PCI Express. MSIs are
an alternative way of generating an inter-
rupt through special messages that allow
the emulation of a pin assertion or
deassertion.
network interface controller/card (NIC)
A computer circuit board or card that is
installed in a computer so that it can be
connected to a network.
NIC partitioning (NPAR)
On QLogic Converged Network Adapters
and Intelligent Ethernet adapters, refers to
the partitioning of a single NIC port into up
to four (nonARI or NPAReP disabled) or
eight (ARI and NPAReP enabled)
individual physical functions or partitions,
each with a user-configurable bandwidth
and personality (interface type). Personali-
ties can include NIC (with or without
RDMA), FCoE, and iSCSI.
PCI Express (PCIe)
A third-generation I/O standard that allows
enhanced Ethernet network performance
beyond that of the older peripheral compo-
nent interconnect (PCI) and PCI extended
(PCI-X) desktop and server slots.
