ESXi 5.0 introduces a new generation of virtual hardware with virtual machine hardware version 8, which includes the following new features:
  1. 32-way virtual SMP. ESXi 5.0 supports virtual machines with up to 32 virtual CPUs, which lets you run larger CPU-intensive workloads on the VMware ESXi platform.
  2. 1TB virtual machine RAM. You can assign up to 1TB of RAM to ESXi 5.0 virtual machines.
  3. Nonhardware accelerated 3D graphics for Windows Aero support. ESXi 5.0 supports 3D graphics to run Windows Aero and Basic 3D applications in virtual machines.
  4. USB 3.0 device support. ESXi 5.0 features support for USB 3.0 devices in virtual machines with Linux guest operating systems. USB 3.0 devices attached to the client computer running the vSphere Web Client or the vSphere Client can be connected to a virtual machine and accessed within it. USB 3.0 devices connected to the ESXi host are not supported at this time.
  5. UEFI virtual BIOS. Virtual machines running on ESXi 5.0 can boot from and use the Unified Extended Firmware Interface (UEFI).
