Moving SAS Applications From a Physical to a Virtual VMware Environment

VMware vSphere 4 provides ESX and ESXi "Bare-metal" hypervisors that install directly on top of a 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. The functionality and performance of VMware ESXi and ESX hypervisors are the same; the difference between the two hypervisors resides in their architecture and operational management.
