Hardware Minimum Requirements (based on physical hardware performance, not a virtual environment):
The minimum MM application server requirements (based on physical hardware performance, not a virtual environment) are:
o Processor: 2 GHZ quad core (4 cores)
o Memory: 8 GB of RAM
o Storage: 10 GB of disk space
However, the Hardware Recommended Requirements for a full enterprise application server suggests at least 64 cores and 300 GB of memory, as can be calculated below:
