Rafi K C from India. I am a C developer presently working on Gluster FS, a distributed file system project at Red Hat. Remote Direct Memory Access(RDMA), snapshot creation, data tiering are some of the areas of Gluster I have actively worked on. Improving the performance of the distributed file system is always a challenge and one that I enjoy doing very much. I follow the latest updates in the opensource world. My last presenation was in SDC-India about "Effiecient Data tiering in DS".
