Goal

One challenge with the ODA is calculating the correct OS / Kernel values for memory:

 This note describes the steps to set Kernel parameters

 

The sizing of OSparams and Huge pages is based on the LINUX + Physical memory available. OS parameter sizing is not unique to hardware type.

This note includes references to the OAKCLI RECONFIGURE OSPARAMS which is part of the OAKCLI command line structure and stack.
There are many newer HW versions of the ODA which do not use OAK but use the new DCS stack which include ODACLI and ODAADMCLI commands plus the new UI Console.
While many of the newer X6-2* and X7-2* as well as 18.3 Bare Metal versions of the ODA no longer use OAKCLI, the manual OS parameter settings and guidelines can still be used.
