Medium size reference system

The medium size reference system is constructed with 30 000 Tags of data type double. Tags are getting live data from OPC DA data source with 2 second collection cycle that results total ingestion load of 15 000 values/s. Values are recorded into StreamHistory with default compression settings. One precalculated aggregate (AVG) is collected for each Variable. Additional data ingestion load is created by collecting 3 OPC events/s with standard attributes.

Hardware specification for the reference system can be found in the table below.
