User’s Guide Converged Network Adapter 8200 and 3200 Series Adapters

device

A computer subsystem, such an adapter card, which mediates data in a computer network. The term “device” is used inter- changeably with “target” and “target device”.

driver

The software that interfaces between the file system and a physical data storage device or network media.

dynamic host configuration protocol (DCHP)

Enables computers on an IP network to extract their configuration from servers that have information about the computer only after it is requested.

Enhanced Ethernet

Also called data center Ethernet or converged enhanced Ethernet. Refers to new enhancements to the existing Ethernet standard that eliminate Ethernet’s inherent lossy nature and make 10Gb Ethernet a viable storage networking transport.

Ethernet

The most widely used LAN technology that transmits information between computers, typically at speeds of 10 and 100 million bits per second (Mbps).

failover path

Software feature that ensures data avail- ability and system reliability by assigning alternate path and automatic adapter failover for device resources.

Fast!UTIL

QLogic Fast!UTIL™ Fibre Channel Adapter BIOS utility.

Fibre Channel

High-speed serial interface technology that supports other higher layer protocols such as SCSI and IP, and is primarily used in SANs. Standardized under ANSI in 1994.

Fibre Channel over Ethernet (FCoE)

Fibre Channel over Ethernet. A new technology defined by the T11 standards body that allows traditional Fibre Channel storage networking traffic to travel over an Ethernet link by encapsulating Fibre Channel frames inside Layer 2 Ethernet frames. For more information, visit www.fcoe.com.

Flash

Nonvolatile memory where the boot code is saved. At times, Flash and boot code are used interchangeably.

Internet protocol (IP)

A method by which data is sent from one computer to another over the Internet. IP specifies the format of packets, also called datagrams, and the addressing scheme.

Internet small computer system interface (iSCSI)

Protocol that encapsulates data into IP packets to send over Ethernet connec- tions. An alternative to FCIP.

load balancing

A software feature that improves system performance by balancing device access between multiple ports or adapters for maximum resource efficiency.

local area network (LAN)

Network typically with transmissions less than 5km.
