Software initiator
A software application initiator communicates with a target device. A
software initiator does not require specialized hardware because all
processing is done in software, using standard network adapters.
Storage Navigator Modular 2
A multi-featured scalable storage management application that is used
to configure and manage the storage functions of Hitachi arrays. Also
referred to as “Navigator 2".
Subnet
In computer networks, a subnet or subnetwork is a range of logical
addresses within the address space that is assigned to an organization.
Subnetting is a hierarchical partitioning of the network address space of
an organization (and of the network nodes of an autonomous system)
into several subnets. Routers constitute borders between subnets.
Communication to and from a subnet is mediated by one specific port
of one specific router, at least momentarily. SNIA.
Switch
A network infrastructure component to which multiple nodes attach.
Unlike hubs, switches typically have internal bandwidth that is a
multiple of link bandwidth, and the ability to rapidly switch node
connections from one to another. A typical switch can accommodate
several simultaneous full link bandwidth transmissions between
different pairs of nodes. SNIA.
T
Target
Devices that receive iSCSI requests that originate from an iSCSI
initiator.
TOE
A dedicated chip or adapter that handles much of the TCP/IP processing
directly in hardware. TCP/IP transmission is inherently a CPU-intensive
operation. Therefore, using dedicated hardware that can operate in
parallel with the main processor allows for superior system
performance. Although all iSCSI HBAs have a TOE, a generic TOE only
implements TCP/IP, while an iSCSI HBA implements the iSCSI protocol
in addition to TCP/IP.
