What do vSphere Resource Allocation Settings manage?

vSphere Resource Allocation Settings are specifically designed to manage the distribution of CPU and memory resources among virtual machines (VMs). This functionality is crucial in a virtualized environment, as it allows administrators to ensure that VMs receive the appropriate amount of resources based on their needs and the overall system capacity.

By configuring resource allocation settings, you can prioritize certain VMs, ensure performance stability, and avoid resource contention, which can lead to performance degradation. For instance, you can set resource shares (to determine priority), limits (to cap the maximum resources a VM can use), and reservations (to guarantee a specific level of resources). This fine-tuning helps in managing workloads effectively and achieving optimal performance across the hosted VMs.

The other options deal with different aspects of VM management. Backup settings pertain to data protection, network speed management involves controlling bandwidth for network traffic, and access permissions involve defining user roles and access levels. Each of these areas is important, but they do not fall under the umbrella of resource allocation, which is specifically focused on CPU and memory distribution.
