Progress of SA1 issues

(SA1) PQ11: NGI operations sustainability. From Milestones MS123 (Int task assessment), there is no indication that the sustainability of NGIs has improved since the last assessment in September 2012. This was clearly indicated in the conclusions of the milestone above.

Repository Ongoing problems with the APEL consumer server experienced, which receives the daily load of records from the APEL clients. Despite expectations, the system did not "catch up" as it did in the past. The network problem which occurred over the Easter weekend was the cause of the latest unscheduled downtime.

More disk was added so that the database table can be optimized without filling up the disk, as this is where the I/O contention is. Following discussions with other members of the systems and databases teams at STFC, the service will be migrated to a physical server as it is currently running on a VM. The physical server is also a higher spec. system with SSDs so this should improve the performance issues we are seeing with the additional data load received. The installation of the new system started. The new system is planned to be rolled to production this week assuming verification is passed. The switchover will require about 4 hours downtime on the APEL broker and consumer systems to handle data migration.
