What is vSphere Hypervisor?
vSphere Hypervisor is a free, bare-metal hypervisor from VMware 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 provides a comprehensive suite of tools for managing and optimizing virtualized environments. With vSphere Hypervisor, users can create, manage, and monitor their VMs, as well as perform tasks such as backup and recovery, and migrate VMs between hosts.

FAQ
What is the difference between vSphere Hypervisor and ESXi?
vSphere Hypervisor and ESXi are both hypervisors from VMware, but they have some key differences. vSphere Hypervisor is a free, bare-metal hypervisor, while ESXi is a paid product that offers advanced features, such as vMotion and Fault Tolerance.
Can I use vSphere Hypervisor for production environments?
While vSphere Hypervisor can be used for production environments, it is not recommended, as it has limited scalability and does not support advanced features. For production environments, it is recommended to use ESXi or vSphere.
How do I monitor vSphere Hypervisor?
vSphere Hypervisor can be monitored using the vSphere Client, which provides a range of tools for monitoring and managing VMs and hosts.
