VMware's CPU and memory Shares, Reservations, and Limits resources control.

VMware's CPU and memory Shares, Reservations, and Limits control resource allocation, with Reservations guaranteeing minimums (e.g., 1GHz), Limits setting maximum caps (e.g., 4GHz), and Shares defining relative priorities (e.g., 2x shares gets 2x resources) during contention, ensuring critical VMs get resources while preventing runaway VMs from starving others. Here's a breakdown: || Shares: __What it is: A relative priority setting, only effective when resources are scarce (contention). __How it works: If VM1 has 2000 shares and VM2 has 500 shares, VM1 gets four times the CPU/memory as VM2 during a crunch. __Default: Normal (e.g., 1000 units). __Use case: Prioritize important VMs like database servers over less critical ones. || Reservations: __What it is: A guaranteed minimum amount of CPU (MHz) or memory (MB) that a VM will always receive. __How it works: The ESXi host reserves this physical resource, subtracting it from its total pool. A VM won't power on if its reservation can't be met. __Use case: Critical VMs (e.g., domain controllers, file servers) that can't tolerate performance dips, as explained in the F5 support portal article and this YouTube video. || Limits: __What it is: An absolute upper cap on how much CPU or memory a VM can use, even if more is available. __How it works: Prevents a single "rogue" VM from consuming all host resources, protecting others. __Default: Unlimited (or 100% of the physical capacity). __Use case: Containing a VM with unpredictable workloads, like a testing environment, from impacting production VMs, notes the Broadcom support portal. || In Summary: __Reserve for guaranteed minimums. __Limit for maximum caps. __Share for priority in contested situations.
