determine whether the proxy server is capable of handling the input/output request;
responsive to determining that the proxy server is incapable of handling the input/output request, communicate the input/output request to the accelerator device, wherein the accelerator device is configured to accelerate data transfer operations between the first virtual machine and a storage virtual appliance executing as a second virtual machine of the hypervisor; and
responsive to determining that the proxy server is capable of handling the input/output request, emulate to the hypervisor a functionality of the accelerator device with respect to the input/output request.
2. The information handling system of claim 1 , wherein emulating to the hypervisor the functionality of the accelerator device comprises processing the input/output request and communicating a response of the input/output request to the hypervisor.
3. The information handling system of claim 1 , wherein the proxy server is configured to execute on the hypervisor.
4. The information handling system of claim 1 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a read request for data stored on a cache accessible to the hypervisor.
5. The information handling system of claim 1 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a communication protocol handshake.
6. A method, comprising:
receiving by a proxy server executing on a processor subsystem an input/output request from an application executing on a first virtual machine of a hypervisor, wherein the hypervisor is executing on the processor subsystem;
determining whether the proxy server is capable of handling the input/output request;
responsive to determining that the proxy server is incapable of handling the input/output request, communicating the input/output request to an accelerator device, wherein the accelerator device is configured to accelerate data transfer operations between the first virtual machine and a storage virtual appliance executing as a second virtual machine of the hypervisor; and
responsive to determining that the proxy server is capable of handling the input/output request, emulating to the hypervisor a functionality of the accelerator device with respect to the input/output request.
7. The method of claim 6 , wherein emulating to the hypervisor the functionality of the accelerator device comprises processing the input/output request and communicating a response of the input/output request to the hypervisor.
8. The method of claim 6 , wherein the proxy server executes on the hypervisor.
9. The method of claim 6 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a read request for data stored on a cache accessible to the hypervisor.
10. The method of claim 6 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a communication protocol handshake.
11. An article of manufacture comprising:
a non-transitory computer-readable medium; and
computer-executable instructions for a proxy server carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
receive by a proxy server executing on a processor subsystem an input/output request from an application executing on a first virtual machine of a hypervisor, wherein the hypervisor is executing on the processor subsystem;
determine whether the proxy server is capable of handling the input/output request;
responsive to determining that the proxy server is incapable of handling the input/output request, communicate the input/output request to an accelerator device, wherein the accelerator device is configured to accelerate data transfer operations between the first virtual machine and a storage virtual appliance executing as a second virtual machine of the hypervisor; and
responsive to determining that the proxy server is capable of handling the input/output request, emulate to the hypervisor of the first virtual machine a functionality of the accelerator device with respect to the input/output request.
12. The article of claim 11 , wherein emulating to the hypervisor the functionality of the accelerator device comprises processing the input/output request and communicating a response of the input/output request to the hypervisor.
13. The article of claim 11 , wherein the proxy server is configured to execute on the hypervisor.
14. The article of claim 13 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a read request for data stored on a cache accessible to the hypervisor.
15. The article of claim 13 , wherein determining whether the proxy server is capable of handling the input/output request comprises determining that the proxy server is capable of handling the input/output request if the input/output request is a communication protocol handshake.
