What is the primary purpose of resource pools in VMware vSphere?

The primary purpose of resource pools in VMware vSphere is to compartmentalize CPU and memory resources. Resource pools allow administrators to allocate and manage these resources effectively, providing a way to control how virtual machines utilize the underlying physical hardware. This compartmentalization is particularly important in environments with multiple applications or services running at the same time, as it enables fine-grained control over resource allocation.

By grouping virtual machines into resource pools, an administrator can prioritize workloads, ensuring critical applications have the necessary resources when needed. Additionally, resource pools facilitate the management of resource limits, reservations, and shares, making it easier to balance performance across different workloads. This organizational structure can enhance overall performance and efficiency in a virtualized environment.

In contrast, managing network settings pertains to VM networking configurations, backing up virtual machines focuses on data protection strategies, and increasing storage capacity involves hardware resources or configurations, none of which align with the primary function of resource pools.
