Disable vmmemctl driver

If the ESXi host needs to reclaim additional memory, it is forced to swap. Swapping is less desirable than ballooning. CtlMaxPercent : Limits the maximum amount of memory reclaimed from any virtual machine using the memory balloon driver vmmemctl , based on a percentage of its configured memory size.

Specify 0 to disable reclamation for all virtual machines. These two advanced settings seem to contradict each other; Sched. MaxMemCtl suggests that it could reclaim an unlimited amount of memory via ballooning, but Mem. In this case, Mem. There is also other techniques such as VMware Transparent Page Sharing TPS which is a proprietary solution to transparently share memory pages between virtual machines and eliminating redundant copies of memory pages. Then there is memory compression where ESXi will compress the memory before the need for swapping bad, worst to happen.

But we might talk about those in one of our future posts. If you are over-committing your hosts then this is an important topic to review. With our short blog post, we give you the idea how it works and where to look at the metrics, but one must study further to get the whole picture how all memory management techniques work within VMware infrastructure.
