Specifications
Processing requirements are listed in terms of hardware CPU cores. Only physical cores are counted. In
hyperthreaded systems, logical CPUs do not count as separate cores.
IMPORTANT The recommended disk sizes assume default log levels. If you configure more detailed log
levels, more disk space is required.
