Comparison of Various Virtual Machine Disk Images Performance on GlusterFS and Ceph Rados Block Devices

High availability, scalability and performance in addition to security are some of the important factors for Cloud Computing technology providers have to address. Open sourced solution enable new technology to be widely distributed, tested and improved. Currently we are experimenting open sourced distributed storage system namely Ceph and GlusterFS. Both are addressing the concern stated earlier. We setup two Cloud Computing environments which one is configured with Ceph and another with GlusterFS. We compare the performance of various virtual disk images such as QCOW2, RAW, QED on GlusterFS and Ceph RADOS Block Devices (RBD). We also present our analysis and findings in this paper.
