Dual 2-Gb Fibre Channel to 133-MHz PCI-X Controller
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.
capable of managing multiple I/O operations and
associated data transfers from start to finish without
host intervention.
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).

... Support for flash BIOS PROM Support for subsystem ID 3.3-V and 5.0-V tolerant PCI-X I/O buffers The ISP2312 is designed to interface directly to the PCI or PCI-X bus and operate as a 64-bit DMA bus master. This function is accomplished through a PCI bus interface unit (PBIU) containing an onboard DMA controller. The PBIU generates and samples ...
