Protecting Redundant CUoD Capacity Card from Misuse

  Capacity Upgrade on Demand (CUoD) is implemented with a CUoD capacity card containing a smart chip that is used to verify activation codes. The Activation code is used to tell the software how many CUoD resources the customer is entitled to use. Contained in the Activation code is the information that uniquely identifies the system and capacity card. The Activation code will not work if this information is incorrect. Each CUoD capacity card initially contains no system identification information so the first time the system is booted, the system information is locked into the CUoD capacity card.

    When the CUoD capacity cards are redundant (must be two in the system) and the first time the system is booted, the machine identification information and an Anchor card identification information (the anchor card identification information is guaranteed to be unique, one of a kind) are stored in the CUoD capacity card to lock the CUoD capacity card to the system and the Anchor card. The Anchor card contains a smart chip that stores a unique serial number which is never duplicated. While the Anchor card identification information is guaranteed to be unique, the system identification information can be altered under certain repair action situations.

    The solution to handling the problem of the code to know if there are one or two cards is to create different vital product data (VPD) (data defining the characteristics of the CUoD capacity card) to tell if one or two CUoD capacity cards will be used for the CUoD function and based on this data require either one or two cards to be present when the system identification information and the Anchor card identification info...
