Abstract: A method for data verification in a data storage environment including the steps of (A) sending a command from an initiator to a target, where the command defines an expected data pattern, (B) sending a block write command from the initiator to the target, where the write command initiates sending data from the initiator to the target, (C) comparing data received to the expected data pattern and (D) generating a status indication in response to the comparison.

Abstract: Systems and methods for analyzing data transferred through an SPI data bus are presented. In one exemplary preferred embodiment of the invention, an SPI data probe imitates an SPI device coupled to the SPI data bus and receives data from the SPI data bus so that the data may be analyzed. The SPI data probe transfers the data to an analysis unit without substantially altering impedance more than the SPI device would. The SPI data probe includes connectors configured for coupling the probe to the SPI data bus and for coupling the probe to an analysis unit. The SPI data probe also includes circuitry that may buffer, compensate and deskew the data as an SPI device would.

Abstract: A communications layer is provided between a host-based SCSI initiator and a SCSI target device to fully automate the validation process. The communications layer allows the host to direct variation and modification of the target parameters and behavior using vendor unique commands. The behavioral modification aims to establish interoperability by conforming the behavior of the target to the host behavior. The host-based initiator transports a suitable command structure to the target device containing appropriate ones of the vendor unique commands and associated parameter data. The target executes and otherwise processes the command structure to effectuate a reconfiguration according to the specifics of the command code. The command code is sufficient to fully reconfigure the SCSI target. Accordingly, the reconfiguration process is carried out in a fully automated fashion.
