MASS STORAGE VIRTUALIZATION FOR CLOUD COMPUTING

摘要

Aspects of the present disclosure relate to systems and methods for virtualizing mass storage using an interface card, or other special hardware unit, operatively coupled to a host system. In various implementations, the interface device and host system may collectively emulate a mass storage device for another “terminal” computing system in a manner that is transparent to the terminal system. Moreover, in various implementations, a mass storage device may be emulated in a manner that is transparent to the terminal system, without requiring modifications to the terminal platform's hardware or software architecture.

主权项

1. An interface device comprising:
a first communication interface, the first communication interface being a mass storage interface; a second communication interface, the second communication interface being an expansion interface; and a specialized processing unit operatively coupled to said communication interfaces, the specialized processing unit having a mass storage device controller connected to the first communication interface and a memory access interface connected to the second communication interface, wherein the mass storage device controller is configured to receive a mass storage data request through the first communication interface, wherein the memory access interface is configured to notify a host system of the mass storage data request through the second communication interface.
