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