信息技术.小型计算机系统接口2(SCSI-2).第2部分:公共访问方法(CAM).运输和SCSI接口模块

[中文适用范围]： 该国际标准定义了小型计算机系统接口（SCSI）的通用访问方法（CAM）。 本国际标准的目的是定义一种方法，使多种环境可以采用通用程序来支持 SCSI 设备。 CAM 提供了一种结构化方法，用于通过与任何计算机相关联的软件（例如，设备驱动程序）和硬件（例如，主机总线适配器）来支持外围设备。 [外文原描述]： SCSI provides a diverse range of peripherals for attachment to a wide range of computing equipment. Some system manufacturers have developed approaches for SCSI attachment which are widely followed, increasing the applications available for the attachment of SCSI peripherals. In markets where no standard method of attachment exists, however, variations between third party sellers have made it nearly impossible for end users to attach more than one SCSI peripheral to one host bus adapter. In an effort to broaden the application base for SCSI peripherals, an ad hoc industry group of companies representing system integrators, controllers, peripherals, and semiconductors decided to address the issues involved. That effort has evolved into this International Standard. Its purpose is to define a method whereby multiple environments may adopt a common procedure for the support of SCSI devices. The CAM provides a structured method for supporting peripherals with the software (e.g. device driver) and hardware (e.g. host bus adapter) associated with any computer.
