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 TC2201E 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 TC2201E 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.
