Historical tag values from your facilities are stored to disk in directories containing special sets of files. These directories are called history blocks. Sets of history blocks are stored in a particular partition on the disk.
Normal tags are stored in one partition, and a second partition contains auto-summary data. See About the auto-summary partition for more information.
You can use the Operations Control Management Console to view and manage partitions and history blocks.
For more about history blocks, see History Blocks in the AVEVA Historian Concepts Guide.
