SWT2_CPB:

• We rebuilt the remaining three XRootD Proxy servers from EL7 to EL9. All four are now EL9. 

• We experienced issues with XRootD 5.7.1 and attempted various changes, performed different tests, and communicated with XRootD experts. They recommended we switch to 5.7.2 due to performance issues in 5.7.1. They stopped using the std::regex which reduced CPU load, resulting in improved throughput. std::regex was running very slowly. 

• Our site may experience a downtime on 1/2/2026. There is maintenance work being done that requires the building’s power to be switched over to the generator. We will declare a warning downtime for this and be in the data center to monitor during the switchover. 

• We have started implementing Zabbix to move away from Ganglia for alerting. 

OU:

• Running well, just some occasional storage overload because of simultaneous heavy data influx and high I/O jobs
• OU_OSCER_GPU now in production, running actual GPU jobs
• New SLURM version 25.11 being tested now, so we're making progress with cgroups and killing high mem jobs
• Making progress with ipv6 dual stacking, only CE missing now
• More network/transfer testing of new storage on Friday
