University of Cambridge Computer Laboratory - WCDC electrical survey: core infrastructure at risk – Maintenance details

Estates will be performing a survey of the electrical infrastructure in the West Cambridge Data Centre, which will require each of the two power feeds to our racks being individually powered down for short periods of time. All our equipment in these racks is redundantly powered from two feeds, and we do not anticipate any disruption; however we should consider our core infrastructure to be at risk during this work as we will be operating with no power redundancy; disruption would be possible during this work in the event of any problem with the data centre power infrastructure or with individual power supplies on our servers and network equipment.
