Scheduled
The Blanca 05 chassis, which contains all nodes with hostname `bnode05*`, is an experiment in providing low-latency MPI via RoCE. However, the switch in this chassis was installed into the wrong slot, which is preventing the RoCE-capable interfaces from operating.

We have reserved the nodes in this chassis via Slurm, and will be reconfiguring their networking in pursuit of enabling RoCE.

Running jobs on Blanca, as well as general Blanca operation, will be unaffected.
