Abstract
A method, non-transitory computer readable medium and storage controller computing device that retrieves an anchor record from a shared memory of a peer storage controller using a direct memory access (DMA) provider device. The anchor record includes an indication of a message first in first out (FIFO) memory region of the peer storage controller. A work request is obtained from a queue. The work request is inserted into the queue by a client application using an application programming interface (API). One of a plurality of types of the work request is determined. The DMA provider device is instructed based on the determined type of the work request and, when the determining indicates that the work request is a request to send a network message, use the message FIFO memory region of the peer storage controller computing device.
