Emergency Chilled Water Maintenance

June 9 – 10, 2014
Coates, Conte, Hansen, Radon, Rossmann

During early June, 2014, all RCAC systems housed in the Math Sciences building will be unavailable due to an emergency repair to the redudndant chilled-water system serving the MATH datacenter.

A major chilled water line has developed a leak, and must be repaired to prevent the leak from becoming a catastrophic, major outage. Additionally, as summer heat approaches, operating without redundant cooling would likely result in further unscheduled outages.

The affected clusters are:

  • Conte
  • Hansen
  • Rossmann
  • Coates
  • Radon

Carter is housed in a separate datacenter facility, and is unaffected.

To prepare the clusters for this work, system reservations have been installed beginning on June 9, 2014. Any PBS jobs which request a walltime which would take them past 8:00am on 6/9/2014 will not start and will remain in the queue until after the maintenance is completed.

This notice and PBS reservations will be updated once tradespeople are officially scheduled.
