Enterprise workloads have been growing for a while now. As the demands for size and performance in virtual environments also grew Virtual Hard Disk drive formats had to evolve to accommodate them. It was with this in view that a new format of the VHD called the VHDX was introduced a couple of years ago by Hyper – V in Windows Server 2012. This had a much greater Storage capacity, data corruption protection during power loss and optimized structural integrity across dynamic and differencing disks. This was designed to provide better performance across the newer disk with larger sectors. In this presentation we look provide a comprehensive view of the format as well as look at some specific usability scenarios. What has been your experience of this file format? Any specific points of information that you may like to share that could help others in the same boat as you?
