  9. 9. AVReporter Energy Management System Maintenance and Backup SQL Server Datacentre Maintenance: • frequency of performing the maintenance duty is 3 months • maintenance duties: • control of capacity • index examination • elevation of index fragmentation • analysis of logged faults and their correction • the checking of the saving security • checking the working order of the drivers • load testing • checking of the data deletion • archiving of the system logs and event log Database back-up: • transaction log hourly back-up • differential back-up every other day • full back up every week KONsys- AVReporter
  10. 10. Key elements for system planning and implementation When building such a huge or similarly complex energy management system special attention should be paid to the following system characteristics: • the HDD performance and the number of IO expressions dictate high attention to detail when logging huge amount of data • when handling a huge database it is advised to handle the operation system, the SQL database and the SQL Logging data in a separate RAID • also it is highly important when building such a huge and complex system to choose a hard drive with the right speed. Slow hard drives it is not possible to complete virtual calculations between the SQL data. • When using huge quantities of virtual meters take advantage of the Realtime Virtual Meters instead of the Advanced Virtual Device Manager, as this one runs the calculations between the data stored in the SQL data base, which means more demanding IO expressions and strain on the SQL server. The Realtime Virtual Meter runs the expressions in the memory, so needs a lot less capacity. • When operating high numbers of pre-scheduled reports, the report generation should not be all done at once in avoidance of the possible overloading of the SQL server. • The old and not any more necessary data’s deletion should be done regularly in smaller batches to keep the performance of the SQL server steady. Also the deletion for huge data quantity can block the SQL server’s logging. KONsys- AVReporter
