CHPC - Datacenter power maintenance – Maintenance details

Rocky Mountain Power has just notified us of a planned power outage to the Downtown Data Center and vicinity this Sunday, March 16, at 9am to address some urgent electrical changes for the city. The CHPC systems with power backed up by generators (the Protected Environment, network, data storage, and virtual machines) will be fine, but the systems with battery backup only will need to be shut down. Therefore we will shut down the general environment clusters lonepeak, kingspeak, notchpeak, and granite at 8AM on Sunday March 16. We estimate these servers will be down for several hours.
