Abstract

A network-attached storage apparatus is configured to be in communication with a local device. The apparatus includes storage devices for storing data, one interface for establishing communication with the network and another interface for establishing communication with the local device. A processor enables the interfaces to alternatively establish communication with the local device or the network.

Claims

1. A network-attached storage device configured to be in communication with a local device, comprising:

a plurality of storage devices to store data;

a first interface to establish communication with a network;

a second interface to establish communication with the local device;

at least one processor to;

selectively enable the second interface to establish communication with the local device;

perform RAID (Redundant Array of Independent Disks) partitioning of the data stored in the plurality of storage devices, where the RAID partitioning of the data comprises organizing the data across the plurality of storage devices according to a RAID storage technique; and

provide status information of the plurality of storage devices to the local device in response to detecting connection of the local device to the network-attached storage device, wherein the status information includes a file structure of the data stored in the plurality of storage devices; and

a peripheral device interface to transfer data between the network or the local device and a peripheral device connected to the network-attached storage device.

2. The network-attached storage device of claim 1, wherein the second interface is to communicate with the local device over a USB bus.

3. The network-attached storage device of claim 1, wherein the second interface is to communicate with the local device over an IEEE 1394 bus.

4. The network-attached storage device of claim 1, wherein the at least one processor is to enable the first interface to establish communication with the network when there is no communication between the second interface and the local device.

5. The network-attached storage device of claim 1, further comprising a switch, the switch when set to a first mode selectively instructing the at least one processor to enable the second interface to establish communication with the local device, and the switch when set to a second mode selectively instructing the at least one processor to enable first interface to establish communication with the network.

6. The network-attached storage device of claim 1, further comprising a storage device interface to access data stored in the plurality of storage devices.

7. The network-attached storage device of claim 1, wherein the at least one processor is to further:

terminate communication between the network-attached storage device and the network in response to detecting connection of the local device to the network-attached storage device.

8. The network-attached storage device of claim 1, wherein organizing the data comprises striping the data across the plurality of storage devices.

9. The network-attached storage device of claim 1, wherein providing the status information allows the local device to treat the plurality of storage devices as being connected directly to the local device.

10. A method comprising:

storing, by a network-attached storage device that includes a first interface, a second interface and a peripheral device interface, data in a plurality of storage devices;

communicating, by the network-attached storage device, with a network through the first interface;

communicating, by the network-attached storage device, with a local device through the second interface;

selectively enabling, by at least one processor in the network-attached storage device, the second interface to establish communication with the local device;

transferring data between the network or the local device and a peripheral device through the peripheral device interface;

performing, by the at least one processor, RAID (Redundant Array of Independent Disks) partitioning of the data across the plurality of storage devices, where the RAID partitioning of the data comprises organizing the data across the plurality of storage devices according to a RAID storage technique; and

in response to detecting connection of the local device to the network-attached storage device, providing, by the at least one processor, status information of the plurality of storage devices to the local device, wherein the status information includes a file structure of the data stored in the plurality of storage devices.

11. The method of claim 10, wherein communicating with the local device through the second interface is over a USB bus.

12. The method of claim 10, further comprising:

setting a switch to a first mode to selectively instruct the at least one processor to enable the second interface to establish communication with the local device; and

setting the switch to a second mode to selectively instruct the at least one processor to enable the first interface to establish communication with the network.

13. The method of claim 10, further comprising:

terminating, by the at least one processor, communication between the network-attached storage device and the network in response to detecting connection of the local device to the network-attached storage device.

14. The method of claim 10, wherein organizing the data comprises striping the data across the plurality of storage devices.
