This might also be another helpful link. Remember, these are 'side of the box' recommendations and as I like to say, Enterprise deployments (at scale) will define actual requirements. Do also look at the Discovery best practices in learning how to get the most out of your resources.

Is there a calculation table where it shows what specifications are needed for the MID server when discovering 1000, 2000, 3000 devices and so on

 

Thanks for the feedback!

The MID server sizing would not be impacted by the quantity of CI's to be discovered.   The key factors of MID server sizing is how many instances are running on the machine (1, 2, 3... for example) and how may other SN products are using the same MID (Disco, Orchestration, Integrations , etc.) and threads setup for use by Java.   Java likes CPU and memory.   For most situations, a MID with 8GB or 12GB will be fine -- but you can and should monitor the MID performance using the MID dashboard.

The # of CI's is less important because at any one moment, only a few CI's are being interrogated... even if you have 10 million CI's in your CMDB, the MID sizing isn't really affected by that metric.
