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.
