Abstract
A computerized system and method for provide increased data throughput for a virtual driver. The system includes a SCSI (Small Computer System Interconnect) port manager; a miniport driver operatively coupled to the SCSI port manager; and a network interface operatively coupled to the miniport driver. Upon receiving indication that a SCSI command has been completed, the miniport driver issues a request to the SCSI port manager causing the SCSI port manager to issue a function call into the miniport driver. As a result, the function call to complete the request is in the SCSI port manager's context. The method includes calling a first routine in a first module to deliver a data packet; sending a function request to a second module that causes the second module to call a second routine in the first module. As a result, the second routine is called in the proper context.
