Product Description
ꢀ Availablein two speed grades (collectively referred
to as ISP2200A):
The ISP2200A is a single-chip, highly integrated, bus
master, Fibre Channel processor that targets storage,
clustering, and networking applications. This chip
connects the PCI bus to a Fibre Channel loop or to a
point-to-point Fibre Channel port.
ꢀ 66-MHz, 64-bit PCI host bus interface
(ISP2200A/66)
ꢀ 33-MHz, 64-bit PCI host bus interface
(ISP2200A/33)
The ISP2200A/33 is pin compatible with the
ISP2100A/33.TheISP2200A/66ispincompatiblewiththe
ISP2100A/66.
ꢀ Compliance with PCI Local Bus Specification
revision 2.2
The ISP2200A is a fully autonomous device, capable
of managing multiple I/O operations and associated data
transfers from start to finish without host intervention.
ꢀ Supports full-duplex communications in all Fibre
Channel topologies
ꢀ Compliance with ANSI SCSI standards for class 2
The ISP2200A provides power management support in
accordancewiththe PCIBusPowerManagementInterface
Specification. The ISP2200A block diagram is illustrated
in figure 1.

ꢀ Fibre Channel Fabric Loop Attachment
(FC-FLA) working draft, rev 2.7, August 12,

ISP Initiator/Target SCSI and IP Firmware
The ISP2200A firmware implements a multitasking
host adapter that provides the host system with IP
communications and complete SCSI command and data
transport capabilities, thus freeing the host system from the
simultaneous execution of SCSI and IP traffic. The
firmware provides two interfaces to the host system: the
command interface and the Fibre Channel transport
interface. The single-threaded command interface
facilitatesdebugging,configuration,andrecoveringerrors.
The multithreaded transport interface maximizes use ofthe
Fibre Channel and host buses.
ꢀ Fibre Channel Private Loop SCSI Direct Attach
(FC-PLDA) working draft, rev 2.1,
September 22, 1997
ꢀ Fibre Channel Tape (FC-TAPE) profile,
T11/98-124vD, rev 1.13, February 3, 1999
ꢀ SupportsFibre Channel protocol SCSI(FCP-SCSI)
and Fibre Channel IP protocols
ꢀ Compliance with PCI Bus Power Management
Interface Specification Revision 1.0 (PC98)
ꢀ Supports up to 200 Mbytes/sec sustained Fibre
The ISP2200A can operate simultaneously in SCSI
initiator and target modes, and supports SCSI and IP
protocols concurrently.
Channel data transfer rate
ꢀ Supports SCSI initiator, initiator/target, and target
modes
ꢀ Onboard, enhanced RISC processor
ꢀ Onboard gigabit serial transceivers
ꢀ Supports PCI dual-address cycle and cache
Software Drivers
The ISP2200A supports a host software interface
similar to the QLogic parallel SCSI and FC-AL processor
family. Existing ISP2100A software drivers for all major
operating systems are easily modified to support the
ISP2200A. The ISP2200A also supports FCP-SCSI and IP
software drivers for most major operating systems.
commands
ꢀ No host intervention required to execute complete
SCSI and IP operations
ꢀ Supports multi-ID aliasing in target mode
ꢀ Supports external frame buffering for performance
scalability over long distances
