Can I deploy VMware vSphere 5 using ESX?
Starting with VMware vSphere 5, ESXi is only hypervisor option available to deploy vSphere. VMware ESXi’s smaller code base and lack of reliance on a general purpose operating system make it the more reliable and secure choice. Its compact design allows it to be embedded in mainstream physical servers for simpler and faster deployments. VMware ESXi was also designed with simplicity in mind. Its menu-driven startup and automatic configurations make it the easiest way to get started with VMware virtualization. VMware recommends that customers migrate existing ESX deployment to ESXi when upgrading to vSphere 5 or vSphere 4.1.Before migrating you should consider the following points before deploying ESXi or switching from ESX to ESXi: • Make sure your hardware is supported on ESXi as the hardware compatibility list (HCL) is not identical to ESX. In general, VMware ESX has a larger HCL due to its support for legacy servers but expect support parity for ESXi and ESX on all new servers. • Mak
