What is vSphere Hypervisor?
vSphere Hypervisor is a free, bare-metal hypervisor that allows users to virtualize their servers and run multiple virtual machines (VMs) on a single physical host. It is a key component of the vSphere suite of products, which provides a comprehensive platform for building and managing virtual infrastructures. With vSphere Hypervisor, users can consolidate their servers, improve resource utilization, and reduce costs.
Key Features of vSphere Hypervisor
