Emergency Chilled Water Maintenance
During early June, 2014, all RCAC systems housed in the Math Sciences building will be unavailable due to an emergency repair to the redundant 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.
