Abstract

A system may include information handling system devices connected together to form a computing cluster utilizing a SCSI interface. Each one of the information handling system devices may include an operating system kernel having a SCSI networking module for encapsulating Internet Protocol (IP) packets for transmitting between the information handling system devices. The system may also include SCSI hardware for connecting the information handling system devices together. The SCSI hardware may be configured to transmit the encapsulated IP packets between the information handling system devices.

Claims

1. A system, comprising:

a plurality of information handling system devices connected together to form a computing cluster utilizing a SCSI interface, each one of the plurality of information handling system devices including an operating system kernel having a SCSI networking module for encapsulating Internet Protocol (IP) packets for transmitting between the plurality of information handling system devices; and

SCSI hardware for connecting the plurality of information handling system devices together, where the SCSI hardware is configured to transmit the encapsulated IP packets between the plurality of information handling system devices.

2. The system of claim 1, wherein a SCSI address for at least one of the plurality of information handling system devices is utilized as a Media Access Control (MAC) for the at least one of the plurality of information handling system devices.

3. The system of claim 1, wherein the SCSI networking module utilizes target mode emulation to designate an initiating one of the plurality of information handling system devices as a target for a Command Descriptor Block (CDB) packet.

4. The system of claim 1, wherein the SCSI networking module provides at least one of multicast or broadcast emulation by providing a plurality of individual I/O requests to the plurality of information handling system devices in the computing cluster.

5. The system of claim 1, wherein one of the encapsulated IP packets is transmitted in the form of a SCSI Write I/O request to one of the plurality of information handling system devices.

6. The system of claim 1, wherein the computing cluster utilizes Single Route I/O Virtualization (SRIOV) to segregate block I/O and cluster traffic within the computing cluster.

7. The system of claim 1, wherein the computing cluster implements zoning to isolate a port associated with a failed node within the computing cluster.

8. A method, comprising:

clustering a plurality of information handling system devices utilizing a SCSI interface, each one of the plurality of information handling system devices including an operating system kernel having an SCSI networking module;

encapsulating Internet Protocol (IP) packets for transmission between the plurality of information handling system devices utilizing the SCSI networking module; and

transmitting the encapsulated IP packets between the plurality of information handling system devices utilizing the SCSI interface.

9. The system of claim 8, further comprising:

designating a SCSI address for at least one of the plurality of information handling system devices as a Media Access Control (MAC) for the at least one of the plurality of information handling system devices.

10. The system of claim 8, further comprising:

designating an initiating one of the plurality of information handling system devices as a target for a Command Descriptor Block (CDB) packet.

11. The system of claim 8, further comprising:

emulating at least one of multicasting or broadcasting by providing a plurality of individual I/O requests to the plurality of information handling system devices.

12. The system of claim 8, further comprising:

transmitting one of the encapsulated IP packets in the form of a SCSI Write I/O request to one of the plurality of information handling system devices.

13. The system of claim 8, further comprising:

segregating block I/O and cluster traffic within the computing cluster utilizing Single Route I/O Virtualization (SRIOV).

14. The system of claim 8, further comprising:

zoning the plurality of information handling system devices to isolate a port associated with a failed node.

15. A system, comprising:

a plurality of information handling system devices connected together to form a computing cluster utilizing a SCSI interface, each one of the plurality of information handling system devices including an operating system kernel having a SCSI networking module for encapsulating Internet Protocol (IP) packets for transmitting between the plurality of information handling system devices; and

SCSI hardware for connecting the plurality of information handling system devices together, where the SCSI hardware is configured to transmit the encapsulated IP packets between the plurality of information handling system devices, wherein a SCSI address for at least one of the plurality of information handling system devices is utilized as a Media Access Control (MAC) for the at least one of the plurality of information handling system devices.

16. The system of claim 15, wherein the SCSI networking module utilizes target mode emulation to designate an initiating one of the plurality of information handling system devices as a target for a Command Descriptor Block (CDB) packet.

17. The system of claim 15, wherein the SCSI networking module provides at least one of multicast or broadcast emulation by providing a plurality of individual I/O requests to the plurality of information handling system devices in the computing cluster.

18. The system of claim 15, wherein one of the encapsulated IP packets is transmitted in the form of a SCSI Write I/O request to one of the plurality of information handling system devices.

19. The system of claim 15, wherein the computing cluster utilizes Single Route I/O Virtualization (SRIOV) to segregate block I/O and cluster traffic within the computing cluster.

20. The system of claim 15, wherein the computing cluster implements zoning to isolate a port associated with a failed node within the computing cluster.
