1Introduction 1 Adapter Overview Note Though this manual covers the PMC and PCI single-ended and differential SCSI-2 adapters, only the MPMC101 Single-ended PMC SCSI-2 Adapter is currently supported by Motorola. The PCI Adapter is a single slot, fast and wide SCSI-2 (Small Computer System Interface - 2) that provides high throughput connectivity for open systems applications. The PMC Adapter provides the same level of performance for workstations with embedded PMC (PCI Mezzanine

Introduction 1 Combined with a 32-bit/33-MHz PCI (Peripheral Component Interconnect) interface into local CPU memory, the adapters provide a total wide and fast pathway for data, which is especially important for servers, image processing, high-speed networks, and other high performance peripherals. They 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 specificat

Supported Software Drivers 1 Supported Software Drivers The software drivers for the PCI and PMC Adapters are contained in the Windows NT 3.51 and the AIX 4.1 operating systems, respectively. Note The PMC Adapter and the PCI Adapter use the same software drivers. Whether the adapter is installed to a PCI slot (PCI Adapter) or to a PMC mezzanine slot (PMC Adapter), the selection of a driver is based upon the operating system in use by the host computer; not by the configur

Introduction 1 PCI Overview Peripheral Component Interconnect (PCI) was developed by IntelÕs Architecture Lab, along with leading computer vendors, to overcome the bottlenecks associated with traditional 16-bit expansion slots, operating at 8 MHz, or essentially 5 megabytes per second. The result was a local bus system capable of transferring 32 bits of data at 33 MHz for a maximum data transfer rate of 132 megabytes per second. The PCI Local Bus takes peripherals off t

Introduction to SCSI-2 1 Introduction to SCSI-2 SCSI (Small Computer System Interface) is an I/O bus protocol that provides high performance, peer-to-peer data communications for up to 16 devices, including one or more host computers. The main advantage for using SCSI-2 is that all the initialization information is stored within the SCSI-2 device. The hostÕs operating system can obtain all the pertinent information about the device without referencing external setup files or software

Introduction 1 In a SCSI-2 system, a computer with a host-adapter serves as the primary initiator for all actions on the SCSI bus. All other devices connected to the bus are SCSI targets. Figure 1-2 above illustrates a simple configuration where a host computer is connected to a single target, a disk drive with an embedded SCSI controller. The controller can be a stand-alone device with multiple peripherals as shown in Figure 1-3. SCSI Controller Printers Host Computer Peripheral Peri

Introduction to SCSI-2 1 The SCSI-2 architecture allows for multiple devices on the bus where more than one host computer can communicate with more than one target at a time. They can be daisy-chained together in a narrow configuration using a 50-conductor, 8-bit cable to connect up to 8 SCSI devices on the bus. A wide configuration expands the bus to a 68-conductor, 16-bit bus that can handle up to 16 SCSI devices. They can be intermixed on the same bus. Peripheral Host SCSI Comp

Introduction 1 All SCSI devices are required to operate using asynchronous data transfers. Synchronous transfers are optional, and negotiated between the host and target during power-up. There are two electrical alternatives, single-ended and differential. They are electronically incompatible and can not be mixed on the same physical bus. Cable lengths up to 25 meters can be used for differential systems. Single-ended configurations can be up to 6 meters. The overall performance of the t
