interswitch link
See ISL.
IOD
In-order delivery. A parameter that, when set, guarantees that frames are either delivered in order or
dropped.
IP
Internet Protocol. The addressing part of TCP.
IQN
iSCSI qualified name.
iSCSI
Internet Small Computer Systems Interface. A protocol that defines the processes for transferring block
storage applications over TCP/IP networks by encapsulating SCSI commands into TCP and transporting
them over the network by IP. See also SCSI.
iSCSI Gateway Service
The HP Multi-protocol SAN Routing Service that maps the FCP protocol to the IP transport. This service
projects iSCSI hosts onto the backbone fabric of a gateway switch.
ISL
Interswitch link. A Fibre Channel link from the E_Port of one switch to the E_Port of another. See also E_Port.
JBOD
Just a bunch of disks. A number of disks connected in a single chassis to one or more controllers. See also
RAID.
LED
Light-emitting diode. Used to indicate the status of elements on a switch.
Loop Mode
One of two possible modes for an L_Port, in which the L_Port is in an arbitrated loop, using loop protocol.
An L_Port in Loop Mode can also be in Participating Mode or Nonparticipating Mode.
LSAN
Logical storage area network. An LSAN enables device and storage connectivity that spans two or more
fabrics. The path between devices in an LSAN can be local to a fabric or cross one or more FC routers and
one or more backbone fabrics.
LSAN zone
The mechanism by which LSANs are administered. An FC router attached to two fabrics listens for the
creation of matching LSAN zones on both fabrics. If this occurs, it creates phantom domains and FC-NAT
entries as appropriate, and inserts entries for them into the name servers on the fabrics. LSAN zones are
compatible with all standard zoning mechanisms.
Mbit/sec
Megabits per second.
