Upgrades to Facility Will Require Multi-Day Outage in Early 2017

December 5, 2016 by Rebecca Hartman-Baker

There are upgrades to the electrical and plumbing systems in the NERSC machine room that must be performed in the new year. The electrical upgrade will increase the reliability of the electrical system that feeds power to the machines, and the plumbing system upgrade will increase the capacity of the water cooling system that keeps the supercomputers cool.

Unfortunately, these upgrades will require multi-day outages of the entire machine room. We are currently trying to figure out how best to schedule the outages (and in particular, whether we can overlap them to reduce the time NERSC users are unable to work). We will more than likely schedule these outages to coincide with one or both of the next two quarterly maintenance periods: February 7 and/or May 9, 2017.

We will keep users informed of our plans for the upgrades as the scheduling decisions are made. Thank you for your patience and please submit a ticket if you have any questions.
