such as PFC configuration and link bandwidth. You can configure DCB to set specific bandwidth
to be allocated to packets depending on their priority values.
F
F_ID
Fabric_Identifier. An entity consisting of one or more switches that interconnect various Nx_Ports
attached to it, and capable of routing frames using only the D_ID information in an FC-2
frame header. An identifier assigned to each fabric in an inter-fabric routing environment.
F_Port
Fabric Port. FC switch ports that connect directly to N_Ports.
Fabric Login
A process by which a Fibre Channel node establishes a logical connection to a fabric switch.
Fabric_Name
A Name_Identifier associated with a fabric.
FC
Fibre Channel. A serial I/O interconnect capable of supporting multiple protocols, including
access to open system storage (FCP), access to mainframe storage (FICON), and networking
(TCIP/IP).
FC-BB
Fibre Channel Backbone. A standard that defines mappings for transporting Fibre Channel over
different network technologies, including operation of Fibre Channel over Ethernet (FCoE).
FCF
FCoE forwarder. FCFs are the combination of FCoE termination functions and Fibre Channel stack
on Ethernet switches (dual-stack switches) and are equivalent to Fibre Channel switches in native
Fibre Channel networks.
FCoE
Fibre Channel over Ethernet. A technology that allows a convergence of Ethernet and Fibre
Channel fabrics.
FCoE_LEP
FCoE Link Endpoint. The data forwarding component of an FCoE entity that handles FC
frame encapsulation/decapsulation, and transmission/reception of encapsulated frames through
a single Virtual Link.
FIP
FCoE Initialization Protocol. A protocol utilized to discover and initialize FCoE capable entities
connected to an Ethernet cloud, such as the FCF. FIP uses a dedicated Ether type of 0x8914.
0FIP does the discovery by allowing ENodes to discover who to log in with, then enabling a
single ENode to communicate with multiple different FC fabrics, and as a result, a one-to-many
relationship is built in. FIP maintains links with Link Keep Alive and Clear Virtual Link functions to
allow a loss of a physical link or logical connectivity to be detected and for both ends of the
virtual link to be notified when this happens. This allows RSCN to function properly and for the
distributed name server to remain in sync. FIP also reduces the security concerns when FIP snooping
and dynamic ACLs are implemented.
FlexFabric
A flexible, virtualization-optimized data center network architecture that requires far fewer devices,
interconnections, layers, and discrete appliances.
FPMA
Fabric Provided MAC Address. A MAC address that is assigned by an FCF and is fabric-wide
unique.
H
hard zone
A zone consisting of zone members that are permitted to communicate with one another through
the fabric. Hard zones are enforced by fabric switches that prohibit communication among
members not in the same zone on a frame by frame basis, based on the source and
destination addressing. Well-known addresses are implicitly included in every zone.
HBA
Host bus adapter. A hardware device that connects the host server to the fabric.
I
IRF
Intelligent Resilient Framework. A software virtualization technology that connects multiple network
devices through physical IRF ports and performs necessary configurations. These devices are then
virtualized into a distributed device. This virtualization technology realizes the cooperation, unified
management, and nonstop maintenance of multiple devices. An IRF virtual device appears as
a node on the network. You can log in to it by connecting to any port of any member to manage
all members of the IRF virtual device.
iSCSI
Internet Small Computer System Interface. A standard protocol that uses SCSI commands to
transfer data over IP networks.
