Its WINASPI Driver. Description - ASPI provides a pass-through interface between the two main components of a software driver: a manger that is written to specific host adapter hardware and a device module or application that is tailored to particular peripheral. SCSI device driver modules and applications submit I/O requests to the host adapter, independent of the SCSI host adapter type. An ASPI manager handles and manages multiple I/O requests from multiple ASPI device driver modules or applications.
