Various embodiments for efficient data transfer in a Remote Direct Memory Access (RDMA) operation by a memory device. A file protocol header of the data is replaced with a block protocol header. The block protocol header enables transfer over a direct data path through a transport layer from a source to a target without outside manipulation by a central processing unit (CPU).

File storage protocols header transformation in RDMA operations

Methods, systems, and computer storage mediums including a computer program product for managing data in a computing network are provided. One method includes registering a plurality of buffers with a work queue in a server and assigning ownership to each of the plurality of buffers to a different working thread in a plurality of working threads. The method further includes continuously polling, by a polling thread, the work queue to determine when work requests are received by the work queue, upon receipt of each work request, and performing each work request on each respective associated buffer by a working thread among the plurality of working threads that owns each respective associated buffer. One system includes a processor for performing the above method and one computer storage medium includes computer code for performing the above method.

Lock-free processing of stateless protocols over RDMA

Methods, systems, and computer storage mediums including a computer program product for managing data in a computing network are provided. One method includes registering a plurality of buffers with a work queue in a server and assigning ownership to each of the plurality of buffers to a different working thread in a plurality of working threads. The method further includes continuously polling, by a polling thread, the work queue to determine when work requests are received by the work queue, upon receipt of each work request, determining which buffer among the plurality of buffers each work request is associated, and performing each work request on each respective associated buffer by a working thread among the plurality of working threads that owns each respective associated buffer. One system includes a processor for performing the above method and one computer storage medium includes computer code for performing the above method.
