METHOD AND APPARATUS FOR REDUNDANCY IN AN ATM USING HOT SWAP HARDWARE UNDERLYING A VIRTUAL MACHINE

摘要

A method and apparatus for providing redundancy in an Automatic Teller Machine (ATM) is provided. Application software may be run on top of a virtual environment such as a virtual machine and/or a virtual disk environment. Should a software component fail, the virtual environment will “crash” but the ATM hardware and operating system will remain intact. If the software is fatally flawed—e.g., due to a faulty “upgrade” the older version may be “rolled back” from a previously stored virtual environment.

主权项

1. An automatic teller machine comprising:
at least one computer comprising:
at least one central processing unit;at least one memory; andat least one device interface; at least one device connected to the device interface; and at least one software program running on the at least one computer comprising at least one virtual environment, wherein a failure in the at least one virtual environment does not cause a failure of the automatic teller machine.
