Project Sizing: 

1. RAM (Most IMPORTANT for Sizing):

   • The most important resource for server sizing is RAM. For any medium to large project, you , which must properly tune your JVM heap size for any medium to a large project.

   • A good rule of thumb is to plan for 1GB to 2GB of heap for every 10K points.

   • Heap size of more than 1.5GB will need to run a 64-bit JVM (the actual max heap size of a 32-bit JVM will vary slightly).

   • 85% of Java Heap consumption is roughly our recommended max before considering to upgrade upgrading the amount of space.

   • Open JDKis recommended, but you can also use Java 11

2. Another important aspect to consider is that the historian is mostly limited mainly by I/O performance (speed of disk drive speed). Using a an SSD will likely have a significant performance boost for reading and writing history data. Disk space is typically not a issue for projects due to the Due to Folio's highly efficient compression techniques, disk space is typically not an issue for projects. Analysis of projects has shown an average of about 1.5 bytes per timestamp sample which equates to about 51KB per , equating year per point for 15min interval data.

3. Depending on the apps/features you use (and don't use) will have a significant significantly impact on performance and how much horsepower you will need to run smoothly.

   • curVal synchronization and his collection typically requires a high amount of bandwidth and CPU processing

   • batch synchronization of history data is typically far more efficient and easier to tune than curVal synchronization

   • how many programs/alarms is will have a big significant impact on CPU processing

   • running multiple projects on a single host consumes more overhead; 100 little projects of 100 points requires require more horse power horsepower than a single 10K point project

4. Max amount of points that should be in the watch at one time should be around 50k

   • How points get into a watch:

     • Trend (Always)

     • Programs (Always)

     • Alarms (Always)

     • Graphics (On View Only)

     • Point Graphics (On View Only)

     • Summaries (On View Only)

5. Database limits

   • Maximum 300 connectors per FIN instance

     Note: If the connectors are organized in folders, each folder can contain 300 connectors. The maximum amount of folders is 300.

   • Maximum 2000 items per tree
