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 platform, which is designed to provide a robust and scalable virtualization infrastructure for data centers and cloud environments.
Main Features of vSphere Hypervisor
vSphere Hypervisor provides a range of features that make it an ideal choice for virtualization, including support for multiple CPU architectures, high-performance networking, and advanced storage management. It also includes features such as VMotion, which allows for live migration of VMs between hosts, and High Availability (HA), which ensures that VMs are always available even in the event of hardware failure.
