ARRA Construction @ Feynman ARRA construction project requires completion by September 30 th. This constraint requires a outage window on Saturday August 13 th to enable subsequent deliverables and activities. Date negotiated with experiment D0, CDF and CMS spokespersons to minimize impact.
ARRA Construction @ Feynman Cooling Upgrade project requires an outage – Electrical work associated with cooling system for the FCC2 computer room – EPO upgrade to new system on FCC2 (including commissioning and testing) – Opportunistic Work Installation of power monitoring for the original FCC 480V service (DOE requirement) Small electrical upgrades & work
Impact to Services Core Services will be unavailable with the exception of network for the duration. Shared Scientific Computing Services will be either unavailable or impacted for the duration. We are working in the interim to mitigate the impact on the network and scientific services.
Outage Schedule Saturday, August 13 Scheduled for 8 hours Tentative start of work is 6:00AM All power and cooling in Feynman is impacted except for the FCC3 HACC computer room
Short Term Actions Understand indicators or predicators Computing load shed plan Cooling in the room reviewed – Increased cooling setpoint from 73F to 77F Review of existing monitoring data Water cooling under condensers at the pad Reduction of vegetation around the pad Augmentation of monitoring at the pad
FESS Engineering Study Engineering Review of the cooling system Determine Root Cause Recommendations & proposals Deliverables from study in late summer Implement any modifications – Prior to Summer, 2012
