5.1.5 Resources used by Management Server

This subsection describes the estimation of resources used by Management Server for each OS.

Note that the Example of option settings in each table of estimation of resources used differs according to the OS and the kernel versions in use. Reference the manual of the OS being used and set up the estimates based on the estimation formula in the table. The settings are not required when the corresponding kernel parameter is not applicable in the OS being used.
