We are writing to inform you of the upcoming Hive cluster outage that we learned about yesterday. PACE has no control on this outage. As part of the design of the Coda data center, we are working with the Southern Company (Ga Power) in the creation and operation of a Micro Grid power generation facility. This is a set of products to enable research of local generation of up to 2MW of off-grid power.
In order to connect this facility/Micro grid to the Coda data center power, Southern Company will need to shut down all power to the research hall in Coda. As a result, Hive cluster will need to be shutdown during this procedure, and we are placing a scheduler reservation to prevent any jobs from running during the shutdown. This is currently planned to begin at 8am on the Georgia Tech MLK Holiday of January 20th. GT has checked to see if this date could be rescheduled to give a longer notice, but GT was unable to change the date. As a result, GT is working with the Southern Company to minimize the duration of this power outage but a final outage time requirement is not known. It is currently expected to be at least 24 hours in length.
The planned outage of the CODA data center has been re-scheduled, and so the Hive cluster will be available until the next PACE maintenance period on February 27. The reservation has been removed, so work should proceed on January 20 as usual.
