Memory Overcommit for Overcommitted Admins - Jonathan Davies, Nutanix

Sign up or log in to save this to your schedule and see who's attending!

Feedback form is now closed.
Overcommitting memory is a useful tool for increasing VM density but typically comes with a increased administration cost as either a) "safe" memory limits need to configured for each VM; or b) unexpected performance problems need to be identified and addressed.

An automatic and lightweight method for determining a VMs working set is described with suggestions on how this could be used in clustered and non-clustered environments to increase VM density with less of an administrative burden.

The presentation also includes a look at the simple model of Linux's paging subsystem that was used to rapidly prototype and evaluate the method's behaviour with different workloads.
