Coverage Metrics for Device Level Validation of SATA and SAS Devices -- An Approach

This paper highlights the significance of Coverage analysis with respect to the functionality and adherence to the standard specification of SATA, SAS, NVME & eMMC Devices (SSD's, HDD's). Coverage analysis aims at achieving an effective way of testing the intrinsic functionality of the storage devices. Commands are issued to the Device under test to validate the attributes such as methods of transfer, latest technology involved to structure the storage device functionality, performance and the adherence to the protocol (SATA protocol). Validation environment of the storage device will include innumerable test cases which lead to redundancy of test scenarios and may cause gaps in the whole validation procedure rendering the goal to achieve a thorough validation output.
