ABSTRACT:
An apparatus, computer program product, and method for preventing piracy in combined hardware/software products, and specifically in RAID storage systems is disclosed. In a preferred embodiment of the present invention, when a hardware device (a disk controller, in a preferred embodiment) is initialized, the device executes firmware that directs it to write a signature to a storage location (scratchpad register) in the device, where the signature corresponds to a set of product features authorized for use with the hardware device. When application code executing on the host computer system attempts to access a feature (e.g., through device driver code), the stored signature is read from the hardware device. The code implementing the feature is allowed to execute only if the signature that is read from the hardware device matches a feature level of the product in which that feature is authorized.
