2 SPES Control System Group Archiver MySQL Computer used for development and implementation of Archiver: Intel Core 2 CPU 2.80Ghz with 2GB RAM, Fedora Release 11 (Leonidas) Services running for the data storage of PV ArchiveEngine: Start at and restart AlarmServer: Start at today enabled LogServer: Start at today enabled ActiveMq: Start at today enabled Mysqld: Start at today enabled CPU Average Usage: 50% when you don't execute query. It's necessary a new PC Network History : very low with hit of 2.0KiB/s 11 Marzo 2010 Giovannini Loris

3 SPES Control System Group Archiver MySQL Actual Data Length into MySQL ALARM: 91 rows 3.19k Archive: rows M Log: rows 1.47 G The retrival of data is very important, Oracle is better then MySQL but is very expensive. We must find a solution and Hypertable may be a good free alternative to solve this IMPORTANT bottle neck. Today we have a benchtest with ONLY 260 PV and we have rows but the Target project was not competed, and the storage of data is a key point for the physics studies. Nowday the PVs running is 1K and is growing up. Tips: Whats about this Archiver on SPES project ????? We must focus on storage and retrival of the data into Hypertable without commodity hardware. 11 Marzo 2010 Giovannini Loris

4 SPES Control System Group Archiver MySQL A genuine request for a new computer is a work requirement of my activity. The extraction, manipulation, and storage of massive records is a very time consuming process on a commodity computer system. A new computer system will eliminate various bottlenecks and develop advanced technologies that will bring true benefit to the physics studies. I will highly appreciate for your immediate and positive cooperation on this matter. 11 Marzo 2010 Giovannini Loris
