You determine the size of an Historian Server as a function of the number of tags from which data is collected, the rate of alarm and event collection, and how often you intend to collect the data and how much data you want to keep online. The number of tags is an indicator of the number of concurrent users likely to access the system. The primary factor is server memory requirements; CPU load is a secondary factor. If the number of concurrent users is significantly different from the suggested guidelines, adjust server memory size accordingly.
The following recommended configurations may vary based on years of data online, update rate, data compression setting, and other tag configuration parameters.
Notes
- Historian Server runs only on 64-bit versions of Windows.
- When possible, for performance reasons, consider using computers with multiple disk drives so that archives and buffers can be given their own drive. Or, multiple data stores can each have their own drive.
- Sustained event rate is 18 million per minute.
- Historian supports Intel Core i3, i5, i7 Duo based processors as long as they are compatible with the operating system.
- Historian does not support Itanium processors.
The recommended configurations may vary based on years of data online, update rate, data compression setting, and other tag configuration parameters.
