  • Page 13: 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.

  • Page 14: Product Features

    Introduction 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 specifications for SCSI-2.

  • Page 15: Supported Software Drivers

    Supported Software Drivers 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.

  • Page 16: Pci Overview

    Introduction 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.

  • Page 17: Introduction To Scsi-2

    Introduction to SCSI-2 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.

  • Page 18: Target With Multiple Peripherals

    Introduction 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.
  • Page 19 Introduction to SCSI-2 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.
  • Page 20 Introduction 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.

  • Page 21: Overview

    2Hardware Installation Overview The PCI and PMC Adapters may be installed in any PCI bus-equipped system. The PCI SCSI-2 Adapter is designed to be installed in PCI expansion slots on the motherboard. The PMC SCSI-2 Adapter resides in a PMC mezzanine in systems so equipped.

  • Page 22: Unpacking The Adapter

    Hardware Installation There are two electrical versions of the PCI and PMC Adapters, a single-ended version and a differential version. Make sure you have the correct type of adapter Caution to match the bus and peripherals being connected. A mixed installation can cause electrical damage to both the peripherals and to the adapter.
