Swiss Grid Operations Meeting on 2019-05-02 at 14:00
Site status
CSCS
Storage
- No special reports for the service
- New (SE) servers installed, starting full data migration soon
- SE servers will have GPFS as backend: this will give more performance and flexibility to the service and is the base for future steps (containers)
- Planning the future of storage01-02: as first step they will be virtualized and then will be consolidated in one (v)server with external chimera (postgres) database
- Servers moved to a new location, on a new network with no impact to the filesystem
- Storage (SSD) moved to the new location
- HDD Tier/pool moved from DDN SF12k to DELL SC9000
- Will double the FC connections squeeze more performance (sometimes I see FC connections reaching the limit)
PSI
UNIBE-LHEP
- Stable running despite lack of maintenance
- Started decommissioning nodes, but re-deployment delayed, since Phoenix hardware is still at CSCS
- Monthly summary: Pledged: 42k, delivered 22k
- Ubelix contributing ~45% (23% typical)
- Running an average >2000 slots (2500 typical during the previous pledge period)
