VMware ESX - the market leading hypervisor, production-proven at thousands of customers of all sizes. VMware ESX abstracts server processor, memory, storage and networking resources into multiple virtual machines. Since 2001 VMware ESX has set the standard for highest levels of performance, scalability and reliability.
VMware ESX and VMware ESXi are “bare metal” hypervisors that partition physical servers in multiple virtual machines. Each virtual machine represents a complete system, with processors, memory, networking, storage and BIOS.
Multiple virtual machines can share physical resources and run side by side on the same server. Operating systems and applications can run unmodified in virtual machines.
