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 suite of products, which provides a comprehensive platform for virtualization, management, and automation of IT infrastructure. With vSphere Hypervisor, users can create and manage virtual machines, allocate resources, and monitor performance, all from a centralized interface.
Main Benefits
The main benefits of using vSphere Hypervisor include increased efficiency, reduced costs, and improved scalability. By virtualizing servers, users can consolidate multiple workloads onto a single physical host, reducing the need for additional hardware and minimizing power consumption. Additionally, vSphere Hypervisor provides advanced features such as live migration, high availability, and fault tolerance, which ensure that virtual machines are always available and running smoothly.
Key Features
Virtual Machine Management
vSphere Hypervisor provides a robust set of features for managing virtual machines, including creation, configuration, and monitoring. Users can create new virtual machines from scratch or clone existing ones, and configure settings such as CPU, memory, and storage. The hypervisor also provides real-time monitoring of virtual machine performance, allowing users to quickly identify and troubleshoot issues.
Resource Allocation
vSphere Hypervisor allows users to allocate resources such as CPU, memory, and storage to virtual machines, ensuring that each VM has the resources it needs to run efficiently. Users can also set resource limits and reservations to prevent over-allocation and ensure that critical workloads have priority access to resources.
Security and Compliance
vSphere Hypervisor provides advanced security features such as encryption, firewalls, and access controls to ensure that virtual machines and data are protected from unauthorized access. The hypervisor also supports compliance with industry standards such as PCI-DSS, HIPAA, and GDPR.
