What is the minimum amount of physical RAM required in a host to meet the hardware configurations for ESXi 8.0?

The minimum amount of physical RAM required in a host to support ESXi 8.0 is 8 GB. This requirement is set to ensure that the hypervisor can operate efficiently and manage virtual machines effectively. Having 8 GB of RAM allows sufficient memory for the ESXi host itself, as well as the ability to allocate memory to virtual machines. This is particularly important as VMware environments often run multiple workloads simultaneously, and adequate RAM is crucial for performance and stability.

While less RAM may technically allow ESXi to be installed, it would not provide a reliable or efficient environment, especially when running multiple VMs. Therefore, the specified minimum of 8 GB aims to support a baseline configuration that can accommodate typical deployments without performance bottlenecks.
