Abstract

A data storage device includes: a housing integrating a control logic, a data protection logic, and a non-volatile storage; and a network interface connector integrated to the housing and is configured to be directly inserted into a network switch. The control logic is configured to store a vehicle data including a video stream in the non-volatile storage. The video stream is received from a video camera that is connected to the network switch. The data protection logic is configured to detect a vehicle event and change an operating mode of the data storage device to a read-only mode prohibiting the vehicle data stored in the non-volatile storage from being erased or tampered.

Claims

1. A data storage device comprising:

a housing integrating a control logic, a data protection logic, and a non-volatile storage; and

a network interface connector integrated to the housing and is configured to be connected to a network switch,

wherein the data storage device is compatible with the NVMe-oF standard,

wherein the control logic is configured to store a vehicle data in the non-volatile storage,

wherein the vehicle data is received from one or more vehicle sensors that are connected to the network switch, and

wherein the data protection logic is configured to detect a vehicle event and change an operating mode of the data storage device to a read-only mode.

2. The data storage device of claim 1, wherein the vehicle event is one or more of an airbag deployment, a sensor trigger, a power loss due to water submersion, and a fire due to a crash.

3. The data storage device of claim 1, wherein the control logic stores the vehicle data in the data storage device for a predetermined period of time after the vehicle event.

4. The data storage device of claim 1, wherein the network interface connector has a small form-factor pluggable (SFP), quad small form-factor pluggable (QSFP), or modular connector form factor.

5. The data storage device of claim 1, wherein the data storage device is an Ethernet-attached solid-state drive (SSD).

6. The data storage device of claim 1, wherein the one or more vehicle sensors include a video camera that is connected to the network switch via an Ethernet connection, and wherein the video camera is configured to send a video stream to the network switch in Ethernet packets.

7. The data storage device of claim 1, further comprising a reserve power and a beacon, wherein the beacon is triggered by the data protection logic after the vehicle event and is configured to generate a beacon signal using the reserve power.

8. The data storage device of claim 1, further comprising an image processor disposed in the housing, wherein the image processor is configured to insert a time stamp and/or a coordinate stamp to the vehicle data.

9. A data storage and retention system comprising:

a network switch comprising a plurality of switch ports and a CPU;

one or more vehicle sensors configured to generate a vehicle data; and

a data storage device comprising a housing that integrates a control logic, a data protection logic, and a non-volatile storage; and

a network interface connector integrated to the housing,

wherein the data storage device is compatible with the NVMe-oF standard,

wherein the one or more vehicle sensors are connected to a first switch port of the network switch and the data storage device is connected to a second switch port of the network switch,

wherein the control logic of the data storage device is configured to store the vehicle data generated by the one or more vehicle sensors in the non-volatile storage, and

wherein the data protection logic of the data storage device is configured to detect a vehicle event and change an operating mode of the data storage device to a read-only mode.

10. The data storage and retention system of claim 9, wherein the vehicle event is one or more of an airbag deployment, a sensor trigger, a power loss due to water submersion, and a fire due to a crash.

11. The data storage and retention system of claim 9, wherein the control logic of the data storage device stores the vehicle data in the data storage device for a predetermined period of time after the vehicle event.

12. The data storage and retention system of claim 9, wherein the network interface connector of the data storage device and at least one of the plurality of switch ports of the network switch have a small form-factor pluggable (SFP), quad small form-factor pluggable (QSFP), or modular connector form factor.

13. The data storage and retention system of claim 9, wherein the data storage device is an Ethernet-attached solid-state drive (SSD).

14. The data storage and retention system of claim 9, wherein the one or more vehicle sensors include a video camera that is connected to the first switch port of the network switch via an Ethernet connection, and wherein the video camera is configured to send a video stream to the network switch in Ethernet packets.

15. The data storage and retention system of claim 9, wherein the data storage device further comprises a reserve power and a beacon, wherein the beacon is triggered by the data protection logic after the vehicle event and is configured to generate a beacon signal using the reserve power.

16. The data storage and retention system of claim 9, wherein the data storage device further comprises an image processor disposed in the housing, wherein the image processor is configured to insert a time stamp and/or a coordinate stamp to a video stream.

17. The data storage and retention system of claim 9, wherein the CPU of the network switch is configured to stitch multiple video streams generated by a plurality of video cameras connected to the plurality of switch ports of the network switch.

18. The data storage and retention system of claim 17, wherein the CPU is configured to generate a spherical video stream using the multiple video streams.

19. The data storage and retention system of claim 9, wherein the CPU is configured to insert a time stamp or a coordinate stamp to the vehicle data.
