Abstract
An inventive apparatus that integrates the operation of a hard disk emulator and a cryptographic accelerator on a single blade server card. An application with cryptographic operations can off load computationally intensive calculations to the cryptographic accelerator so that the speed at which the application performs actions can be increased significantly. Typically, the hard disk emulator is a flash memory component and the accelerator can perform at least modular exponentiation calculations. One bus is employed for communication between the hard disk emulator and the accelerator. Another bus is employed to communicate with other resources off the card. Often, the card is configured to operate as one of a several blade servers in a chassis.
