Oracle^® Dual Port 25 Gb Ethernet Adapter User's Guide

Glossary

A

adapter

The Oracle Dual Port 25 Gb Ethernet Adapter.

D

DAC

Direct attached cables.

DHCP

Dynamic Host Configuration Protocol. Part of the application layer in the Internet protocol suite.

DNS

Domain name system. Translates human-readable domain names into numerical identifiers.

E

EEPROM

Electronically erasable programmable read-only memory.

EMI

Electromagnetic interference. The interference caused by the magnetic fields of electronic components.

G

Gb

Gigabyte.

GbE

Gigabit Ethernet.

Gbps

Gigabits-per-second.

GT

Gigabit-transfer.

GTps

Gigatransfers per second.

L

link aggregation

Link aggregation enables several physical ports to be bundled into a single logical channel.

LC/LC

Little Connector fiber optic cable that connects the transceiver to the adapter. This LC connector is on a small form-factor pluggable transceiver. LC connectors have replaced SC connectors in corporate networking environments because of their smaller size.

LFM

Linear Feet per minute.

LOM

LAN-on-motherboard. A LAN design.

M

MAC

Media access control. Enables the use of a unique address for each device on a network.

Mb

Megabit.

MTU

Maximum transmission unit. The MTU (payload without the Ethernet header) affects how jumbo frames function.

N

NIS

Network Information Service. Originally known as Yellow Pages, NIS is a protocol for distributed system configuration data.

P

PCIe

Peripheral Component Interconnect Express.

PF

Physical function.

PXE

Preboot execution environment. Enables clients to boot over a network interface, independent of the OS or other devices.

R

RDMA

Remote Direct Memory Access. Allows computers in a network to exchange data in main memory without involving the processor, cache, or OS of either computer.

RX

Response. The automatic response mechanism used by Ethernet PAUSE frames.

S

SPI

Serial peripheral interface. A type of flash memory.

SRC

Source code. The SRC RPM is used in Linux to build the driver kernel files.

T

TCP

Transmission Control Protocol. Part of the transport layer of the Internet protocol suite.

transceiver

The 25GbE SFP28 optical transceiver that both ports in the adapter use to transmit data.

TX

Generation. The automatic generation mechanism used by the Ethernet PAUSE frames.

U

UDP

User Datagram Protocol. Part of the transport layer of the Internet protocol suite.

UEFI

Unified Extensible Firmware Interface. Manages the operations between hardware firmware and the OS during the boot time.

V

VF

Virtual function.

VID

VLAN identifier. A 12-bit identifier in an Ethernet header.

VLAN

Virtual LAN. Splits the physical LAN into logical subparts. Multiple VLANs are supported on a single port, enabling a server with a single adapter to have a logical presence on multiple IP subnets.

VXLAN

Virtual eXtensive LAN. A tunneling mechanism for providing isolated virtual Layer 2 (L2) segments that can span multiple physical L2 segments.
