SouthGrid has been busy taking part in the Service Challenge Throughput tests.
Oxford carried out tests on September 26th and 27th. The first Oxford to RALpp went ok although slowly, the second RALPP to Oxford was extremly disapointing. Practically zero bandwidth.
Further iperf tests have been carried out between servers both within Oxford and SouthGrid. At the moment the main cause of the problem seems to be the installation of a new Campus Firewall on August 15th. See: the Gridmon web site.
Work with David Wallom of Oxford Grid has continued in order to enable the NGS VO on Oxford's cluster.
Another worker node PSU failed two weeks ago and was replaced under warrenty by Dell.
