New storage system deployment; planned downtime Dec 26 - 30

We are pleased to report that we have received, installed, and configured a new 3 Petabyte IBM SpectrumScale (GPFS) storage system.

We have completed our initial file transfer from the current system to the new one. Over the coming months, we will need to perform periodic synchronizations of data from the current system to the new system. This may have a performance impact for jobs running on the cluster. We will make every effort to minimize this impact and appreciate your patience.

We will need to pause the old storage system for a final synchronization and to upgrade the software on the compute nodes. We have chosen the week after Christmas in order to minimize impact to ongoing research. The tentative dates are Monday, December 26 through Friday, December 30.

This downtime will affect the following services:

  • The HPC cluster.
    • The Slurm scheduler will stop accepting new jobs at 5pm on December 23, and all running jobs will be killed at 8am on December 26.
  • The GPFS storage system
    • The HPC login nodes, Open OnDemand, Spear nodes, export nodes, and all other public facing servers will be unavailable starting at 8am on December 26.

The following services will see minimal impacts:

  • The Research Archival System
  • Customer VMs
  • Colocation customers' servers

If you have any concerns or issues about the proposed downtime, please let us know:
