Appendix C Calculating the Size of Kernels in Memory

One requirement of vPars is the sum of sizes of the kernels running in memory must be less than 2 GB. This only limits the maximum number of partitions that can be created. If you use the defaults of the dynamic tunables, you will not run into this 2 GB limit. However, if you have adjusted the dynamic tunables, you can perform the calculations described in this appendix to ensure you meet this criteria.

For more information on dynamic tunables, see the white paper Dynamically Tunable Kernel Parameters in HP-UX 11i at http://docs.hp.com.
