Lock-free processing of stateless protocols over RDMA

A system for managing data in a computing environment, comprising:

• one or more host computing devices;
• and
• a storage system comprising a server and storage elements coupled to each of the host computing devices via a network, the server comprising a plurality of buffers and a work queue coupled to a processor, the processor configured for:
• registering a plurality of buffers with a work queue in the server;
• assigning ownership of each of the plurality of buffers to a different working thread in a plurality of working threads such that each working thread is assigned ownership of, and therefore performs only work requests associated with, a respective associated buffer, the buffer comprising a specific region of physical memory in the server;
• continuously polling in lieu of polling at predetermined intervals, by a polling thread in the server, the work queue to determine when the work requests are received by the work queue;
• 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.

A physical computer storage medium comprising a computer program product for managing data in a computing environment including one or more host computing devices coupled to a storage system comprising a server and storage elements via a network, said physical computer storage medium comprising:

• computer code for registering a plurality of buffers with a work queue in the server;
• computer code for assigning ownership of each of the plurality of buffers to a different working thread in a plurality of working threads such that each working thread is assigned ownership of, and therefore performs only work requests associated with, a respective associated buffer, the buffer comprising a specific region of physical memory in the server;
• computer code for continuously polling in lieu of polling at predetermined intervals, by a polling thread in the server, the work queue to determine when the work requests are received by the work queue;
• and
• computer code for 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.
