Product Description
The ISP2300 is a single-chip, highly integrated, bus
master, Fibre Channel processor that targets storage,
clustering, and networking applications. This chip connects
a conventional PCI bus to a 2-gigabit Fibre Channel loop
or to a point-to-point Fibre Channel port.
The ISP2300 is a fully autonomous device, capable of
managing multiple I/O operations and associated data
transfers from start to finish without host intervention.
The ISP2300 balances the advanced bus speeds and
efficiency of PCI with exceptional 2-gigabit Fibre Channel
performance. Fibre Channel support for SCSI, IP, and VI
allows the ISP2300 to target a wide spectrum of storage
and system area networks (SANs). The ISP2300 block
diagram is illustrated in figure 1.
ISP Initiator/Target SCSI, IP, and VI
Firmware
The ISP2300 firmware implements a multitasking host
adapter that provides the host system with IP
communications, complete SCSI command and data
transport capabilities, and VI communications, thus freeing
the host system from simultaneous execution of SCSI, IP,
and VI traffic. The firmware provides two interfaces to the
host system: the command interface and the Fibre Channel
transport interface. The single-threaded command
interface facilitates debugging, configuration, and error
recovery. The multithreaded transport interface maximizes
use of the Fibre Channel and host buses.
The ISP2300 can operate simultaneously in SCSI
initiator and target modes, and supports SCSI, IP, and VI
protocols concurrently.
Software Drivers
The ISP2300 supports a host software interface similar
to the QLogic parallel SCSI and 1-gigabit Fibre Channel
processor families. Existing ISP2100A/2200A software
drivers for all major operating systems are easily modified
to support the ISP2300. The ISP2300 also supports
FCP-SCSI, IP, and VI software drivers for most major
operating systems.
