1Introduction
Overview
The MPMC101 and MPMC102 provide fast and wide SCSI-2 (Small
Computer System Interface-2) high throughput connectivity for
host carrier boards equipped with PMC (PCI Mezzanine Card)
connections. The MPMC101 supports single-ended SCSI-2
connections; the MPMC102 supports differential SCSI-2
connections.
The adapters, combined with a 32-bit/33-Mhz PCI interface into
local CPU memory, provide a total wide and fast pathway for data.
This is especially important for servers, image processing,
high-speed networks, and other high performance peripherals. The
adapters are designed to operate within the framework of todayÕs
open systems architectures by providing physical and data-link
services as defined by the ANSI X3.131 specifications for SCSI-2.
The PMC adapters are plug-and-play devices with systems that are
compliant with the PCI Local Bus Specification (revision 2.0).
