G
Global DCBX
Parameter
Global DCBX parameters take effect on all devices in VFM.
H
HBA Host bus adapter (HBA) is an FC storage network card.
I
I-SID The backbone service instance identifier is the unique number of a VSI. In a single BEB device,
the I-SID indicates the number of the VSI. In an SPBN network, the I-SID indicates the number of
an SPB service.
Inactive zone set In a VSAN, there is only one active zone set and other zone sets are inactive. zones in an inactive
zone set cannot control access to N_Ports of servers or storage devices.
Ingress RB An ingress RB is the node through which a frame enters the TRILL network.
Interface DCBX
parameter
The DCBX parameter which takes effect on the interface in VFM.
L
LSDB A link state database (LSDB) contains all link state information in the SPB or TRILL network.
LSPDU A link state data unit (LSPDU) describes local link state information and is advertised between
neighbor devices.
N
N mode/N_Port All ports on nodes (servers and storage devices) are in N mode. Port in N mode is called N_Port.
Ports in N mode include N_Ports and NL_Ports. An N_Port directly connects to a fabric. An
NL_Port connects to a fabric through an arbitrated loop.
NP mode/NP_Port In a SAN network, a port is called NP_Port when it is operating in NP mode. An NP_Port connects
to the F_Port of another switch. VFM does not manage NP_Ports.
NPV mode When an FCoE switch is operating in NPV mode, it can connect to the N_Port on a node (a
server or a storage device) through its F_Port or to the F_Port on an FCF switch through its NP_Port.
NPV switch An FCoE switch is an NPV switch when it is operating in NPV mode. Its VFC interfaces support
F mode (F_Port) and NP mode (NP_Port). VFM does not manage NPV switches.
P
Port mode In a switched fabric, servers, storage devices, and FC switches communicate with each other
through ports of different modes. Ports of servers and storage devices are in N mode. Ports of
FC switches are in E mode, F mode, NP mode, or Auto mode.
R
RB A routing bridge (RB) is a device that runs TRILL. RBs are classified into ingress RBs, transit RBs,
and egress RBs, depending on their position in the TRILL network. A frame enters the TRILL network
through an ingress RB, travels along transit RBs, and leaves the TRILL network through an egress
RB.
S
SAN Storage area networks (SAT) enable the universal connectivity of servers, network devices, and
storage devices and allow the servers to store, access, and back up data of high storage scalability
and availability. Servers connect to the storage devices and read or write data through the network
devices.
