Glossary: Dell PowerVault 35F User's Guide
the media and interface, including drivers, transceivers, connectors, and cables. Mounts on a FC adapter
card and connects the PowerVault 35F to a FC host. Also referred to as a Physical Link Module (PLM).
Hardware Path
See FC-SCSI Hardware Path
Host Bus Adapter
See FC Adapter.
Indexed Addressing
A menu name. It allows for generic Fibre Channel host bus adapters to access SCSI devices attached to the
PowerVault 35F using a table which is indexed by sequential LUN values.
Initiator
A SCSI device (usually a host system) that requests an operation to be performed by another SCSI device
known as the target (for example, a SCSI disk or tape drive).
Link
For Fibre Channel, it is a connection between two nodes, each having at least one N_Port, interconnected
by a pair of optical or copper links, one inbound and one outbound.
Longwave
Lasers or LEDs that emit light with wave lengths around 1300 nm. When using single mode (9 nm) fibre,
longwave lasers can be used to achieve lengths greater than 2Km.
Loop Address
A FC term indicating the unique ID of a node in Fibre Channel loop topology, sometimes referred to as a
Loop ID. Also a status type in the FC Status Menu, showing the FC Loop Address of the PowerVault 35F.
Loop Port (L_Port)
A FC port that supports loops.
LUN
Logical Unit Number or Logical Unit; a subdivision of a SCSI target. For SCSI-3, each SCSI target
supports up to sixteen LUNs (LUN-0 to LUN-16). Using LUNs, the FC host can address multiple
peripheral devices that may share a common controller.
Management Information Base (MIB)
A structured set of data variables, called objects, in which each variable represents some resource to be
managed. A related collection of resources to be managed.
Mapping Table
A table which is indexed by sequential LUN values, indicating selected BUS:TARGET:LUN devices. It is
used by the PowerVault 35F to perform Fibre Channel-to-SCSI operations by default.
