Abstract:
To address the limitations of OpenNebula storage subsystems, we have designed and developed an extension that is capable of achieving higher I/O throughput than the prior subsystems. The semi-shared storage subsystem uses central and distributed resources at the same time. Virtual machine instances with high availability requirements can run directly from central storage while other virtual machines can use local resources. As I/O performance measurements show, this technique can decrease I/O load on central storage by using local resources of host machines.
