ASPI

Ø  ASPI:

      ASPI (Advanced SCSI Programming Interface) is a software layer that manages communication between SCSI devices and software applications. The ASPI manager software provides an interface between ASPI modules (device drivers or applications with direct SCSI support), a SCSI host adapter, and SCSI devices connected to the host adapter. The ASPI manager is specific to the host adapter and operating system; its primary role is to abstract the host adapter specifics and provide a generic software interface to SCSI devices. On Windows 9x and Windows NT, the ASPI manager is generic and relies on the services of SCSI miniport drivers. On those systems, the ASPI interface is designed for applications which require SCSI pass-through functionality (such as CD-ROM burning software).The primary operations supported by ASPI are discovery of host adapters and attached devices, and submitting SCSI commands to devices via SRBs (SCSI Request Blocks). ASPI supports concurrent execution of SCSI commands. Adaptec developed ASPI as a standard for SCSI, but the standard that was developed for IDE devices (ATAPI) also worked through ASPI to ensure compatibility .With standard ASPI drivers, you can send the same command to any SCSI card and make the same thing happen with a device. Mostly associated with CD ROMs and CD Writers, it is essential that all the DLL files are consistent and work together when using these drivers.
