Scientific Computing Services upgraded the network connections on 21 PPA virtual machines during a scheduled outage. The link aggregation feature increases total bandwidth and adds redundancy. The Fermi VM migration project is nearing completion and several old Fermi hosts were also shutdown for retirement. The power and rackspace will be reclaimed for future installations.
Scientific Computing Services completed a cycle of applying security patches for the central AFS database servers which handle access and control of Unix home directories and group space for a number of scientific experiments. The work was completed with minimal disruption to the community and ensures that our systems are in compliance with Cyber Safety policies at SLAC.
Scientific Computing Services worked with our AFS support vendor to implement recommendations based on the way AFS is being used at SLAC. The AFS servers were reconfigured and tuned to improve performance for our scientific computing community.
