Title Optimisation of Linux System Settings for Access to the JASMIN/CEMS Panasas Storage
Abstract The JASMIN/CEMS super-data-cluster provides fast, parallel storage and a computing environment for UK and European climate and earth observation communities. Deployed at the Rutherford Appleton Laboratory as a joint project between RAL Space and the Scientific Computing Department, the system comprises a 4.6PB usable parallel storage, collocated with the Lotus HPC compute facility and a virtualisation infrastructure. The JASMIN/CEMS cluster provides the infrastructure for data storage and services for the Centre for Environmental Data Archival, as well as data processing and scientific computation for the climate, earth system science and earth observation communities, including the ISIC/Satellite Applications Catapult funded by the UK Space Agency. Panasas is a very high-performance system which requires a high quality network for optimal performance. Network components and brands behave differently so Panasas recommends spending some time finding the optimal settings for best performance. This report describes the investigation into the optimal system settings for increasing the storage access performance, both from physical hosts and from virtual machines.
