Fixed Interval Marker (FIM)
Fixed interval markers (FIMs) provide a
synch and steering mechanism that is recommended for certain high-
speed iSCSI implementations.
FTP
File Transfer Protocol
H
Host Bus Adapter (HBA)
See iSCSI Adapter.
HVD
High Voltage Differential
I
ID
Numerical identifier
Indexed Addressing
A menu name. It allows for generic Fibre Channel
host bus adapters to access SCSI devices attached to the TC2201 using a
table which is indexed by sequential LUN values.
Initiator
A device (usually a host system) that requests an operation to be
performed by another device known as a target (usually a peripheral).
Initiator Mode
Configuration mode of the TC2201 in which a Fibre
Channel initiator requests operations to be performed by a SCSI target
device.
IP
Internet protocol
iSCSI (Internet SCSI)
iSCSI is Internet SCSI (Small Computer System
Interface), an Internet Protocol (IP)-based storage networking standard
for linking data storage resources, developed by the Internet Engineering
Task Force (IETF). By carrying SCSI commands over IP networks, iSCSI is
used to facilitate data transfers.
iSCSI Portal Groups
A Portal Group defines a set of Network Portals
within an iSCSI Network Entity that collectively supports the capability
of coordinating a session with connections spanning these portals. Not all
Network Portals within a Portal Group need participate in every session
connected through that Portal Group. One or more Portal Groups may
provide access to an iSCSI Node. Each Network Portal, as utilized by a
given iSCSI Node, belongs to exactly one portal group within that node.
iSNS
iSNS allows the administrator to go beyond a simple device-by-
device management model, where each storage device is manually and
individually configured with its own list of known initiators and targets.
Using iSNS, each storage device subordinates its discovery and
management responsibilities to the iSNS server. The iSNS server thereby
serves as the consolidated configuration point through which
management stations can configure and manage the entire storage
network.
