Classic storage subsystem

Note: The Classic Storage subsystem is now replaced by the Classic Data Redirector process (aahStoreSvc.exe), which performs the same functionality.

Starting with AVEVA Historian 2014 R2, classic storage as a subsystem no longer exists. However, all historical data that was collected by the Classic Storage subsystem from previous releases remains fully accessible in a seamless manner.

Any tags previously configured for classic storage will automatically use storage after you install AVEVA Historian 2014 R2 or later.

Starting with AVEVA Historian 2014 R2, data from the following sources are accepted by a classic storage "redirector" service (aahStoreSvc.exe) and sent to the current Storage subsystem.

• A remote IDAS that has not been upgraded to Historian 2017

• System driver
