ISP2312 Data Sheet
Dual 2-Gb Fibre Channel to 133-MHz PCI-X Controller
The ISP2312 is a highly integrated single-chip,
dual-channel, bus master, Fibre Channel processor
that targets storage, clustering, and networking
applications. This chip connects a conventional PCI
bus or PCI-X bus to a 2-Gb Fibre Channel loop or to
a point-to-point Fibre Channel port.
ꢀ Compliance with PCI Bus Power Management
Interface Specification Revision 1.1 (PC99)
ꢀ Compliance with ANSI SCSI standards for
class 1, class 2, class 3, and intermix Fibre
Channel service:
ꢀ Second Generation FC Generic Services
Definition (FC-GS-2), NCITS 288.200x,
Project 1134-D, revision 5.3
The ISP2312 is a fully autonomous device,
capable of managing multiple I/O operations and
associated data transfers from start to finish without
host intervention.
ꢀ Third Generation FC Generic Services
Definition (FC-GS-3) draft, revision 6.2
The ISP2312 balances the advanced bus speeds
and efficiency of PCI-X with exceptional 2-Gb Fibre
Channel performance. Fibre Channel support for
SCSI, IP, and VI allows the ISP2312 to target a wide
spectrum of storage and system area networks
(SANs).
