Per the IBM documentation for External S-TAP requirements the below is listed as the minimum requirements for a non Kubernetes deployment:

• An x86_64 processor.
• Minimum RAM memory 500 MB and 2 GB storage.

Is there any sort of model used to help determine if more than the minimum resources should be used to run the E-TAP when load expectancy is high?

No.  That minimum is what's required for a single External S-TAP instance running in docker.  Each External S-TAP will take approximately 500Mb of RAM, so if you need to run more than one External S-TAP on a single node, you should have enough memory for each.  Determining how many External S-TAPs are needed in tandem to handle the load is best determined with test loads.  A typical deployment would be a pair of nodes each running a single External S-TAP container configured for 4 worker threads.

HI,

How many databases can be connected through External S-TAP's maximum(load balancing) for single Linux machine with hardware( 4 gb ram and 500 gb Hard disk)?
It is non-kubernetes deployment.

Thanks,

Each External S-TAP can only have one database target.  Maximum number of External S-TAPs that can run on that hardware is 8 (500Mb * 8 = 4Gb), though placing the maximum that can fit is obviously not the best for performance or reliability.  I recommend testing the load as each deployment is created in order to find what works best in your environment for the processing loads you anticipate.
