Abstract

A system includes a data shuttle with rows of data storage devices, which are communicatively coupled to a shared printed circuit board assembly. Each row includes multiple data storage devices. The printed circuit board assembly is configured to communicatively couple to a first controller to enable storing data to the data storage devices and to communicatively coupled to a second controller to enable transferring data from the data storage devices.

First claim

We claim:

1. A system comprising:
an outer chassis including multiple storage bays;
a data shuttle removably coupled to a first storage bay of the multiple storage bays and including rows of data storage devices, which are communicatively coupled to a shared printed circuit board assembly, wherein each row includes multiple data storage devices;
a latch movable between a latched position and an unlatched position; and
a controller programmed to check whether it is permissible to remove the data shuttle from the first storage bay by determining whether data transfer operations have completed and to cause the latch to move from the latched position to the unlatched position based on the determining.

2. The system of claim 1 , wherein the data storage devices are positioned on a single level of the data shuttle.

3. The system of claim 2 , wherein the data shuttle includes three rows of data storage devices and each row includes four data storage devices.

4. The system of claim 3 , wherein the data storage devices are hard disk drives.

5. The system of claim 4 , wherein the data storage devices are 3.5″ form factor hard disk drives.

6. The system of claim 2 , wherein the data storage device are arranged to minimize a height of the data shuttle.

7. The system of claim 1 , wherein the data shuttle does not include its own controller positioned within the data shuttle.

8. The system of claim 1 , wherein the data shuttle does not include an air mover positioned within the data shuttle.

9. The system of claim 1 , wherein the data shuttle does not include a power supply unit positioned within the data shuttle to power the data storage devices.

10. The system of claim 1 , wherein the data shuttle includes a chassis that is sized to fit into a docking station that is separate from the outer chassis.

11. The system of claim 1 , wherein the data storage devices are not communicatively coupled to each other.

12. The system of claim 1 , further comprising:
a rack that includes sub-enclosures,
at least one of the sub-enclosures is a high-density storage sub-enclosure, which includes a separate set of data storage devices positioned along multiple levels and multiple rows,
at least one of the sub-enclosures is an ingest unit sub-enclosure with the multiple storage bays, the ingest unit sub-enclosure including a second controller functionally positioned between the data shuttle and the other sub-enclosures and configured to transfer data from the ingest unit sub-enclosure to the data storage devices positioned in the high-density data storage sub-enclosure.

13. The system of claim 12 , wherein the high-density storage sub-enclosure is a 12U-sized enclosure.

14. The system of claim 13 , wherein another one of the sub-enclosures comprises a second high-density storage sub-enclosure that includes a second 12U-sized enclosure.

15. The system of claim 14 , wherein the ingest unit sub-enclosure comprises only four storage bays.

16. The system of claim 1 , wherein the data storage devices rest on their respective larger area surfaces on an interior surface of the data shuttle.

17. The system of claim 1 , wherein the data shuttle includes rails coupled to opposing sides of a chassis of the data shuttle.

18. The system of claim 17 , wherein the rails comprise nylon.

19. The system of claim 1 , further comprising a button configured to cause the controller to check whether it is permissible to remove the data shuttle from the first storage bay.

20. The system of claim 19 , wherein the button is externally accessible.
