Abstract
A solid state disk system is disclosed. The system comprises a user token and at least one level secure virtual storage controller, coupled to the host system. The system includes a plurality of virtual storage devices coupled to at least one secure virtual storage controller. A system and method in accordance with the present invention could be utilized in flash based storage, disk storage systems, portable storage devices, corporate storage systems, PCs, servers, wireless storage, and multimedia storage systems.
Claims31
A secure and scalable solid state disk (SNS-SSD) system having at least a three level architecture comprising:
- a user token for providing an independent user authorization utility for access to the system following boot of a host system;
- at least one first level secure virtual storage controller, coupled to the host system through a host interface;
- at least two second level secure virtual storage controllers,
- wherein the host system can interface directly with at least one of the two second level secure virtual storage controllers, at least one of the at least two second level secure virtual storage controllers includes a direct interface to and is directly compatible with the at least one first level secure virtual storage controller and at least one of the at least two second level secure virtual storage controllers includes at least a plurality of device interfaces;
- and
- a plurality of third level virtual storage devices coupled to the at least one level secure virtual storage controller for interfacing therewith,
- wherein each of the at least one first level secure virtual storage controller and at least one of the at least two second level secure virtual storage controllers have a substantially similar architecture and at least one differing device interface.
A secure and scalable solid state disk (SNS-SSD) system having at least a three level architecture comprising:
- a user token for providing an independent user authorization utility for access to the system following boot of a host system;
- a first level secure virtual storage controller, coupled to the host system;
- a plurality of second level secure virtual storage controllers, each of the second level secure virtual storage controllers having a direct interface with and being directly compatible to the first level secure virtual storage controller, wherein the host system can interface directly with at least one of the two second level secure virtual storage controllers, and at least one of the at least two second level secure virtual storage controllers includes at least a plurality of device interfaces;
- and
- a plurality of lower levels of second level virtual storage devices coupled to the plurality of upper levels of second level secure virtual storage controllers,
- wherein each of the first level secure virtual storage controller and at least one of the plurality of second level secure virtual storage controllers have a substantially similar architecture and at least one differing device interface.
