Hello guys,

Is there any standard calculation for the allocation of sql server maximum memory on sql server instances? So lets assume there is an instance A with a database of 500GB and an instance B with 2 databases of 250GB how do I use a standard method of allocating memory to these instances.

Thank you

Not really that way, depends on the database activity, the portion of the DB that is heavily used, the workload and a whole bunch of other things.

For what to leave for the OS, see chapter 4 of
For calculating memory requirements, this may help:
