The VMs with older hardware are supported on newer version of VMware v Sphere.The Default VM Compatibility – can be set per host or per cluster. As the transition to out of the classical v Sphere client, this feature is available only through the v Sphere Web Client, as in future releases of v Sphere, the standard C v Sphere Client will be phased out.The possibility to use tools like v Tune or Oprofile. Virtualized Hardware Virtualization – VHV – Improved virtualization of the CPU. Runs Windows 7/8 in XP mode with better performance.And I'm sure that also nested ESXi will run smoother too… As I said earlier, the VMware Tools should now require less reboots.This disk format has a new granular block allocation size of 4kb.(A redo log format used 512 bytes which was an issue for alignment and partial writes).VMware v Sphere 5.1 brings Virtual Hardware version 9.But before I'll show you what new features are in this hardware, I'd like to point out theat the things are changing the way you'll need to keep up with the latest VMware tools.
Reclaim Storage Space from deleted files– (View only) – by using SESparce VMDK virtual disk format – Space Efficient Sparse Disk Format.I'll discuss the web client in another post since there is a lot to say on that.There are some big advantages through using the web client, but also inconveniences (for MAC users mostly), because the web client uses Flash.They try to say like, don't upgrate the VM unless you really want to benefit the latest features and capabilities.They try to eliminate a pressure to keep “up-to-date” to the latest version.
