Abstract

A method, non-transitory computer readable medium, and storage controller computing device that establishes an application interface and a source interface to a programmable switch. A flow table of the programmable switch is updated to insert routing actions associated with the application and source interfaces.

Next, when an application request received from an application is locally serviceable is determined. When the determination indicates the application request is not locally serviceable, a migration request for data associated with the application request is sent to the programmable switch from the source interface and a destination address of a source storage server is used. Additionally, a migration response to the migration request including the data from the source storage server is received from the source interface. The data is then stored locally in a destination storage server and thereby is migrated from the source storage server.

Claims

establishing, by a storage controller computing device, an application interface and a source interface to a programmable switch;

updating, by the storage controller computing device, a flow table of the programmable switch to insert routing actions associated with the application interface and the source interface; and

sending, by the storage controller computing device, a migration request for data associated with the application request to the programmable switch from the source interface and using a destination address of a source storage server;

receiving, by the storage controller computing device and from the source interface, a migration response to the migration request including the data from the source storage server; and

storing, by the storage controller computing device, the data locally in a destination storage server.

2. The method of claim 1, further comprising when the determining indicates the application request is not locally serviceable, sending, by the storage controller computing device, the application request to the source storage server to be serviced by the source storage server, the sending comprising sending the application request to the programmable switch from the source interface and using a destination address of the application.

3. The method of claim 1, further comprising when the determining indicates the application request is not locally serviceable, sending, by the storage controller computing device, an application response to the application request to the programmable switch from the application interface and having a destination address of the application.

4. The method of claim 1, wherein the routing actions comprise sending any packet received from:

5. The method of claim 1, further comprising instructing, by the storage controller computing device, the programmable switch to quiesce prior to the updating and to resume normal operation subsequent to the updating.

6. The method of claim 1, wherein the programmable switch is compliant with an OpenFlow protocol and the updating further comprises invoking an OpenFlow Controller (OFC) Application Programming Interface (API).

7. A storage controller computing device comprising a processor and a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to:
