CHPC DOWNTIME: CHPC Network Upgrade, Dec 15, 2020 starting at 8am

CHPC will be having a downtime to replace (upgrade) the CHPC core network switch in the Downtown Data Center on December 15th, starting at 8am.  The switches are being replaced with new hardware obtained via CARES act funding.  The new hardware will  both provide the capability of increased network speeds as well as adding redundancy at this core switch.

During this downtime there will be NO ACCESS to any CHPC resource.  This includes resources in both the general and the protected environment, and includes the compute clusters, the Windows servers, stand-alone servers, all storage, all virtual machines, and hosted websites.

There are reservations in place on all of the clusters to empty the slurm batch queue of running jobs by 7:30am on Dec 15th.

If all goes as anticipated,  the resources in the general environment will start to become accessible in early afternoon, starting with the storage and VMs, and then to the clusters interactive nodes and the Windows server Beehive.  

Access to the resources in the protected environment will be restored late afternoon.

Please log out of all CHPC resources before the start of the downtime (including closing FastX sessions).  For users on the Windows servers, please save your work before the start of the downtime.

During the downtime, we will send updates as CHPC resources become accessible.
