System and method for storage device management

A method for managing storage devices, the method comprising:

• receiving a request from a host device;
• updating a global submission queue in response to receiving the request;
• identifying a first storage device from a plurality of storage devices;
• transmitting the request to the first storage device;
• updating a submission queue corresponding to the first storage device in response to transmitting the request to the first storage device;
• and
• updating a global completion queue and a completion queue corresponding to the first storage device in response to completion of the request by the first storage device.

A storage device, comprising:

• a housing having a plurality of ports configured to receive storage devices;
• and
• a storage management device disposed within the housing and comprising:
• a memory comprising a global submission queue and a global completion queue;
• and
• a processor communicatively coupled to the memory, and configured to:
• receive requests from the host device and communicate the requests to the storage devices via the plurality of ports;
• receive responses from the storage devices via the plurality of ports and communicate the responses to the host device;
• update the global submission queue and a submission queue corresponding to a first storage device of the storage devices in response to receiving the requests;
• update the global completion queue and a completion queue corresponding to the first storage device in response to completion of the requests.

An external storage device, comprising:

• a host interface configured to communicatively couple with a host device having a first read/write speed;
• a plurality of storage device interfaces configured to communicatively couple with storage devices having a second read/write speed less than the first read/write speed;
• and
• a memory comprising a host input/output queue, wherein the host input/output queue is larger than an input/output queue of each of the storage devices, wherein the host input/output queue comprises a global submission queue and a global completion queue, the storage device further comprising a processor configured to:
• receive a first request from the host device via the host interface and communicate the first requests to a first storage device of the storage devices via the plurality of storage device interfaces;
• receive a first response from the first memory storage device via the plurality of storage device interfaces and communicate the first responses to the host device via the host interface;
• update the global submission queue and a submission queue corresponding to the first storage device in response to receiving the first request;
• and
• update the global completion queue and a completion queue corresponding to the first storage device in response to completion of the first request.

A data storage device, comprising:

• means for receiving requests from a host device;
• means for storing the requests within a memory;
• means for identifying a first storage device and a second storage device based on a first one of the requests and a second one of the requests;
• means for communicating the first one of the requests to the first storage device and the second one of the requests to the second storage device;
• means for receiving a response from the first storage device and a response from the second storage device;
• means for updating a global submission queue corresponding to the host device based on the first and second requests, updating a submission queue corresponding to the first storage device based on the first second request, and updating a submission queue corresponding to the second storage device based on the second request;
• and
• means for updating a global completion queue corresponding to the host device based on the first and second responses, a completion queue corresponding to the first storage device based on the first response, and a completion queue corresponding to the second storage device based on the second response.

A client device for storage device management, the client device comprising:

• a load balancing module configured to distribute input/output commands of a host device to a plurality of removable storage devices;
• a queue management module configured to:
• update the global submission queue and global completion queue;
• and
• update submission queues and completion queues of the plurality of removable storage devices;
• a global mapping table comprising an indexing of data stored within each of the plurality of removable storage devices, and an identifier for each of plurality of removable storage devices;
• and
• a command acknowledgement module configured to communicate an acknowledgement from each of the plurality of removable storage devices to the host device.
