We’ve talked previously about how CPU Ready is something you want to monitor in your environment and how the best way to prevent/cure CPU Ready issues is to properly allocate vCPUs to VMs. As I’m reading the updated vSphere 5.1 Performance Best Practices; however, I’m finding some other good reasons to allocate vCPUs correctly.
These 4 (lesser known) reasons to correctly size vCPU allocations were also listed in previous iterations of the document, but they are worth a refresher.
As usual, I hope this has been beneficial and that your world is now a better place. If you have other thoughts or comments that will benefit the community, please post them below.
