- We are starting to plan the termination of the FTS2 service now that almost all use is on FTS3.
- Maintenance will be carried out on the diesel generator tomorrow morning (22nd May) from 09:00 - 11:00. Should we suffer a mains power failure during this time window we will not have generator backup.
- On Wednesday 28th May we plan to move the network switches for some Castor disk servers to the mesh network to alleviate a bottleneck. This will be during an at risk on Castor.
Listing by category:
- Databases:
- Switch LFC/FTS/3D to new Database Infrastructure.
- Castor:
- Castor 2.1.14 testing was largely complete, although a new minor version (2.1.14-12) will be released soon.
- Networking:
- Move switches connecting recent disk servers batches ('11, '12) onto the Tier1 mesh network.
- Make routing changes to allow the removal of the UKLight Router.
- Fabric
- We are phasing out the use of the software server used by the small VOs.
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
- There will be circuit testing of the remaining (i.e. non-UPS) circuits in the machine room during 2014.
