Systems and methods for out-of-band booting of a computer
View Patent ↗The present invention is directed to systems and methods for remotely booting a server computer system. A boot request is received from the server computer. An access request is transmitted to a boot management system via a secondary communication channel in response to the received boot request. An access response is received from the boot management system. The access response includes boot data from a boot image accessible via the boot management system and compatible with the server computer. In response to the received access response, the boot data is extracted from the access response and forwarded to the server computer for processing and booting. Multiple responses may be required in certain instances to accumulate the entirety of the boot image.

4. The computer-implemented method of claim 2 , wherein the local request comprises a reference to the data at the local computer; and wherein prior to transmitting the access request to the remote computer through the second communication interface, retrieving the data from the local computer.
5. The computer-implemented method of claim 2 , wherein the access request comprises a request to display the data on a display device, to print the data through a printing device, or to write the data on a storage device.
6. The computer-implemented method of claim 1 , wherein the target peripheral comprises a storage device at the remote computer; wherein the access request comprises a request for data from the storage device; and wherein the access response comprises the data from the storage device.
7. The computer-implemented method of claim 6 , wherein the access request comprises a request for retrieving boot data from a boot image compatible with the local computer from the storage device; wherein the access response comprises the boot data from the boot image compatible with the local computer.
8. The computer-implemented method of claim 6 , wherein the access response comprises a plurality of access responses from the storage device, each of the access responses comprising a segment of the data.
9. The computer-implemented method of claim 1 wherein the access request and the access response are encrypted prior to transmission or are transmitted via an encrypted communication protocol.
10. The computer-implemented method of claim 1 , wherein the first communication interface is configured to connect to a hot swap interface of the local computer.
11. A remote access device comprising:
a first communication interface configured to connect the remote access device to a hot swap interface of a local computer;
a second communication interface configured to connect the remote access device to a secondary communication channel for communicating with a remote computer; and
a system processor in communication with the first and second communication interfaces, the system processor configured to:
receive a local request from the local computer through the first communication interface,
in response to receiving the local request from the local computer, transmit an access request to the remote computer through the second communication interface, the access request comprising a request for accessing the target peripheral at the remote computer, and
upon transmitting the access request to the remote computer through the second communication interface, receiving an access response from the remote computer acknowledging whether the access request was successfully completed.
12. The remote access device of claim 11 , wherein the target peripheral comprises an output device at the remote computer; and wherein the access request comprises a request to output data through the output device.
13. The remote access device of claim 12 , wherein the local request comprises a reference to the data at the local computer; and wherein prior to transmitting the access request to the remote computer through the second communication interface, retrieve the data from the local computer.
14. The remote access device of claim 11 , wherein the target peripheral comprises a storage device at the remote computer; wherein the access request comprises a request for data from the storage device; and wherein the access response comprises the data from the storage device.
15. The remote access device of claim 14 , wherein the access request comprises a request for retrieving boot data from a boot image compatible with the local computer from the storage device; wherein the access response comprises the boot data from the boot image compatible with the local computer.
16. A computer-storage medium having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to:
receive at a remote access device a local request from a local computer through a first communication interface;
in response to receiving the local request from the local computer, transmit an access request to a remote computer through a second communication interface, the access request comprising a request for accessing a target peripheral at the remote computer; and
upon transmitting the access request to the remote computer through the second communication interface, receive an access response from the remote computer acknowledging whether the access request was successfully completed.
17. The computer-storage medium of claim 16 , wherein the target peripheral comprises an output device at the remote computer; and wherein the access request comprises a request to output data through the output device.
18. The computer-storage medium of claim 17 , wherein the local request comprises a reference to the data at the local computer; and wherein prior to transmitting the access request to the remote computer through the second communication interface, retrieve the data from the local computer.
19. The computer-storage medium of claim 16 , wherein the target peripheral comprises a storage device at the remote computer; wherein the access request comprises a request for data from the storage device; and wherein the access response comprises the data from the storage device.
20. The computer-storage medium of claim 19 , wherein the access request comprises a request for retrieving boot data from a boot image compatible with the local computer from the storage device; wherein the access response comprises the boot data from the boot image compatible with the local computer.
