VMware Cross-Cloud Architecture

CPU and memory shares, reservations, and limits

CPU and memory configurations for virtual machines are highly configurable in ESXi. This gives the flexibility to configure the following:

• Shares: These allow an administrator to set a relative priority to a virtual machine's access to CPU or memory. When there is contention on the system, higher-priority workloads have a higher chance of using the resource.
• Reservations: These allow an administrator to guarantee CPU or memory to a virtual machine. In this case, no other resource will be able to utilize the assigned resources.
• Limits: These allow an administrator to limit the amount of physical resources that a virtual machine can consume. This can be useful in simulating contention or in preventing ...
