HPC Hyper-Converged Virtualized Software-Defined Storage Framework
TimeTuesday, July 246:30pm - 8:30pm
DescriptionBoth hardware and software for HPC storage systems are complex, difficult to administer, unreliable, and performance sensitive. Virtualizing HPC storage systems would increase the reliability, manageability, and flexibility of these systems, allowing them to be converged with more general cloud, big data, and high-end computing systems. This project is examining a wide range of HPC storage virtualization architectures, focusing on the performance costs of different approaches to running the Lustre Parallel File System inside VMware virtual machines on commodity Dell hardware. As part of this work, researchers are examining the costs and benefits of pass-through and full virtualization of the Infiniband fabric in the context of storage system workloads. They are also researching the potential reliability gains of VM-based replication of key system software components such as the Lustre metadata server.
