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.

First claim

What is claimed is:

1. A method comprising:
receiving a data from one or more sensors that are connected to a network switch via a network interface of a data storage device, wherein the data storage device is accessible using a network address;
storing the data in a non-volatile storage of the data storage device;
detecting an event based on the data received from the one or more sensors; and
changing an operating mode of the data storage device to a read-only mode based on detection of the event.

2. A data storage device comprising:
a control logic, a data protection logic, and a non-volatile storage; and
a network interface connector configured to be connected to a network switch,
wherein the data storage device is accessible using a network address,
wherein the control logic is configured to store a data in the non-volatile storage,
wherein the data is received from one or more sensors that are connected to the network switch, and
wherein the data protection logic is configured to detect an event based on the data received from the one or more sensors and change an operating mode of the data storage device to a read-only mode based on detection of the event.

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

4. The data storage device of claim 2 , wherein the control logic stores the data in the data storage device for a predetermined period of time after the event.

5. The data storage device of claim 2 , wherein the network interface connector has a small form-factor pluggable (SFP), quad small form-factor pluggable (QSFP), or modular connector form factor.

6. The data storage device of claim 2 , wherein the data storage device is a network-attached solid-state drive (SSD).

7. The data storage device of claim 2 , wherein the one or more sensors include a video camera that is connected to the network switch via a network connection, and wherein the video camera is configured to send a video stream to the network switch in network packets.

8. The data storage device of claim 2 , further comprising a reserve power and a beacon, wherein the beacon is triggered by the data protection logic after the event and is configured to generate a beacon signal using the reserve power.

9. The data storage device of claim 2 , further comprising an image processor, wherein the image processor is configured to insert a time stamp and/or a coordinate stamp to the data.

10. A data storage and retention system comprising:
a network switch comprising a plurality of switch ports and a CPU;
one or more sensors configured to generate a data; and
a data storage device comprising a control logic, a data protection logic, and a non-volatile storage; and a network interface connector,
wherein the data storage device is accessible by a network address,
wherein the one or more 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 data generated by the one or more sensors in the non-volatile storage, and
wherein the data protection logic of the data storage device is configured to detect an event based on the data generated by the one or more sensors and change an operating mode of the data storage device to a read-only mode based on detection of the event.

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

12. The data storage and retention system of claim 10 , wherein the control logic of the data storage device stores the data in the data storage device for a predetermined period of time after the event.

13. The data storage and retention system of claim 10 , 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.

14. The data storage and retention system of claim 10 , wherein the data storage device is a network-attached solid-state drive (SSD).

15. The data storage and retention system of claim 10 , wherein the one or more sensors include a video camera that is connected to the first switch port of the network switch via a network connection, and wherein the video camera is configured to send a video stream to the network switch in network packets.

16. The data storage and retention system of claim 10 , 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 event and is configured to generate a beacon signal using the reserve power.

17. The data storage and retention system of claim 10 , wherein the data storage device further comprises an image processor, wherein the image processor is configured to insert a time stamp and/or a coordinate stamp to a video stream.

18. The data storage and retention system of claim 10 , 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.

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

20. The data storage and retention system of claim 10 , wherein the CPU is configured to insert a time stamp or a coordinate stamp to the data.
