VMware Resource Allocation

[Pourya]

Hello,

Would someone point me to some documentations that discusses the difference between the various flavors of resource allocation. I hear the terms "allocation", "reservation", "shares", "pools", and I'd like to know the performance implications of each of these.

Thanks

Welcome to the forums - here is it in short -

Allocation - Is the amount of memory the O/S can access - For CPU the maximum amount of CPU cycles can have is equal to the cycles that are provided by a single core since a virtual cpu can only run on one core at a time

Resrvation - certain amount of memory (measured in MB) or CPU (measured in MHz) reserved for the virtual machine

Shares - a way to prioritize delivery of CPU and Memory resources to the VMs when there is contention for that resource

Pools are way to carve up the resources in a single host or a DRS Cluster
