Abstract

An embodiment of a semiconductor package apparatus may include technology to provide a first interface between a first storage device and a host device, and provide a second interface directly between the first storage device and a second storage device. Other embodiments are disclosed and claimed.

First claim

We claim:

1 . An electronic processing system, comprising:
a host device having a chassis; a first storage device communicatively coupled to the host device inside the chassis; a second storage device communicatively coupled to the host device inside the chassis; and logic communicatively coupled to the first storage device to:
provide a first interface between the first storage device and the host device, and
provide a second interface directly between the first storage device and the second storage device.

2 . The system of claim 1 , wherein the logic is further to:
provide a peer-to-peer interface for the second interface.

3 . The system of claim 2 , wherein the logic is further to:
provide a third peer-to-peer interface between the first storage device and a third storage device communicatively coupled to the host device inside the chassis.

4 . The system of claim 1 , wherein the logic is further to:
discover one or more storage devices interconnected with the first storage device; and update a local routing table for the first storage device based on the discovered interconnected storage devices.

5 . The system of claim 4 , wherein the logic is further to:
process a data movement command to one or more of move and copy data between two or more of the interconnected storage devices.

6 . The system of claim 1 , wherein one or more of the storage devices includes a solid-state disk device.

7 . A semiconductor package apparatus, comprising:
a substrate; and logic coupled to the substrate, wherein the logic is at least partly implemented in one or more of configurable logic and fixed-functionality hardware logic, the logic coupled to the substrate to:
provide a first interface between a first storage device and a host device, and
provide a second interface directly between the first storage device and a second storage device.

8 . The apparatus of claim 7 , wherein the logic is further to:
provide a peer-to-peer interface for the second interface.

9 . The apparatus of claim 8 , wherein the logic is further to:
provide a third peer-to-peer interface between the first storage device and a third storage device.

10 . The apparatus of claim 7 , wherein the logic is further to:
discover one or more storage devices interconnected with the first storage device; and update a local routing table for the first storage device based on the discovered interconnected storage devices.

11 . The apparatus of claim 10 , wherein the logic is further to:
process a data movement command to one or more of move and copy data between two or more of the interconnected storage devices.

12 . The apparatus of claim 7 , wherein one or more of the storage devices includes a solid-state disk device.

13 . A method of interconnecting storage devices, comprising:
providing a first interface between a first storage device and a host device; and providing a second interface directly between the first storage device and a second storage device.

14 . The method of claim 13 , further comprising:
providing a peer-to-peer interface for the second interface.

15 . The method of claim 14 , further comprising:
providing a third peer-to-peer interface between the first storage device and a third storage device.

16 . The method of claim 13 , further comprising:
discovering one or more storage devices interconnected with the first storage device; and updating a local routing table for the first storage device based on the discovered interconnected storage devices.

17 . The method of claim 16 , further comprising:
processing a data movement command to one or more of move and copy data between two or more of the interconnected storage devices.

18 . The method of claim 13 , wherein one or more of the storage devices includes a solid-state disk device.

19 . At least one computer readable medium, comprising a set of instructions, which when executed by a computing device, cause the computing device to:
provide a first interface between a first storage device and a host device; and provide a second interface directly between the first storage device and a second storage device.

20 . The at least one computer readable medium of claim 19 , comprising a further set of instructions, which when executed by the computing device, cause the computing device to:
provide a peer-to-peer interface for the second interface.

21 . The at least one computer readable medium of claim 20 , comprising a further set of instructions, which when executed by the computing device, cause the computing device to:
provide a third peer-to-peer interface between the first storage device and a third storage device.

22 . The at least one computer readable medium of claim 19 , comprising a further set of instructions, which when executed by the computing device, cause the computing device to:
discover one or more storage devices interconnected with the first storage device; and update a local routing table for the first storage device based on the discovered interconnected storage devices.

23 . The at least one computer readable medium of claim 22 , comprising a further set of instructions, which when executed by the computing device, cause the computing device to:
process a data movement command to one or more of move and copy data between two or more of the interconnected storage devices.

24 . The at least one computer readable medium of claim 19 , wherein one or more of the storage devices includes a solid-state disk device.
