Deploy the Most Reliable Production-proven Hypervisor Architectures
Virtualize even the most resource-intensive applications with the hypervisor architectures that set the industry standard for reliability, performance and cross-platform support.
VMware ESX and VMware ESXi are “bare-metal” hypervisor architectures, meaning they install directly on top of the physical server and partition it into multiple virtual machines that can run simultaneously, sharing the physical resources of the underlying server. Each virtual machine represents a complete system, with processors, memory, networking, storage and BIOS, and can run an unmodified operating system and applications.
vSphere 4.1 and its subsequent update and patch releases are the last releases to include both ESX and ESXi hypervisor architectures. Future major releases of VMware vSphere will include only the VMware ESXi architecture. For this reason, VMware recommends that deployments of vSphere 4.x utilize the ESXi hypervisor architecture.
