SANsurfer FC HBA Manager User’s Guide Management Tool for QLogic FC and FCoE Adapters

„Lower Layer is the SCSI adapter driver. It communicates directly to the SCSI adapter.

Echo diagnostic test

Test that transmits a received signal back to the sender to verify the integrity of the device.

Enhanced Ethernet

New enhancements to the existing Ethernet standard that eliminate Ethernet’s inherently lossy nature and make 10Gb Ethernet a viable storage networking transport. (Also called DataCenter Ethernet or Converged Enhanced Ethernet.)

Fabric

Consists of cross-connected FC devices and switches.

Failover path

Software feature that ensures data avail- ability and system reliability by assigning alternate path and automatic HBA failover for device resources. This feature is avail- able only in Windows 2000/Windows Server 2003/Windows Vista, Novell NetWare, and Red Hat/SUSE Linux. (Windows XP and Windows Server 2008 do not support failover.)

Fast!UTIL

QLogic Fast!UTIL FC HBA BIOS utility.

FC

Fibre Channel. A high-speed serial inter- face technology that supports other higher layer protocols, such as iSCSI and IP, which is primarily used in SANs. ANSI standardized Fibre Channel in 1994.

FCode

A type of boot code designed for use on Sun's SPARC or Apple Macintosh hardware platforms. See Boot code and Flash.

FCoE

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

Flash

Non-volatile memory where the boot code is saved. At times, Flash and Boot code are used interchangeably.

Flash BIOS

Flash programmable read-only memory (PROM) that contains the code for booting from the adapter at startup.

HBA

Host Bus Adapter. The board that inter- faces between the host system and device. HBA is synonymous with host adapter, adapter, and adapter board.

HBA alias

Auser-defined name for an HBA. You may use up to 256 characters when creating an HBA alias.

HBA port

A port on the HBA.

HBA port alias

A user-defined name for an HBA port. You may use up to 256 characters when creating an adapter port alias.
