2022 Storage Service Upgrades

In October 2022, OSC retires the Data Direct Networks (DDN) GRIDScaler system deployed in 2016 and expands the IBM Elastic Storage System (ESS) for both Project and global Scratch services. This expands the total capacity of Project and Scratch storage at OSC to ~16 petabytes with better performance.

System Downtime October 11, 2022

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, Oct. 11 2022. The downtime will affect the Pitzer and Owens Clusters, web portals, and HPC file servers. MyOSC (my.osc.edu) and state-wide licenses will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., Oct. 11 2022. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.

Rolling reboot of Owens and Pitzer starting from July 11, 2022

We will have rolling reboots of Owens and Pitzer clusters including login and compute nodes, starting from 9AM Monday, July 11, 2022, to perform OS updates to address CVE-2022-1966 (https://access.redhat.com/security/cve/CVE-2022-1966). The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on both clusters. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.
