January 2024: Updates to Network Switches

Over the next few weeks (from 31 January 2024), we will be updating the network switches that underpin MASSIVE M3. Each switch takes a short time (i.e., several minutes) to update, but during this update, jobs that are sensitive to the network may be impacted. We will be placing batches of compute nodes on SLURM reservations to ensure that they will be drained of jobs before the updates.

The schedule of work and any potential impact to the service will be provided below.

Update: Feb 09 2024

We have scheduled the first lot of compute nodes for this update on the 13th of February 2024. Work should not take a couple of hours to complete.

Update: Feb 16 2024

Another 28 switches need to be updated and we will be scheduling a downtime for this. This downtime will also be used to perform necessary updates to the Lustre File system, along with other updates.
