VMware ESX Server is virtual infrastructure software for consolidating and managing systems in mission-critical environments. ESX Server speeds service deployments and adds management flexibility by partitioning x86 servers into a pool of secure, portable and hardware-independent virtual machines. Ideally suited for enterprise data centers, ESX Server minimizes the total cost of ownership (TCO) of computing infrastructure by increasing resource utilization, minimizing maintenance downtime and maximizing server manageability.
