Maintenance on the cooling system in the HLR building

2020-05-18…25

Update 2020-05-25:

The cold water cooling system has been cut and welded at the critical joints, so that we can continue cooling with other means.

Since the provider of the coming “Lichtenberg 2” successor system has finished the storage benchmarks during the weekend, we're currently in the process of bringing up the Lichtenberg 1 cluster again.

2020-05-18:

For an extensive repair of the defective main chilling unit and retrofitting of the cold water pipe system, the whole water cooling system is unavailable.

Due to this, no electrical (and thus, heating) device is allowed to be running, and so the whole HPC cluster and the Housing servers in L5|08 need to be switched off.
