Although this topic is not new I had some readers asking me about it. So here we go…
Windows 2012 Hyper-V has a new disk format : VHDX.
VHDX principal features
- Storage capacity up to 64 terabytes (TBs). With the VHDX format we can to create larger virtual hard disks ( up to 64TB). The VHD format has a 2 TB limit to VHD’s.
- Corruption protection during power failures
- Optimal structure alignment for large-sector disks (4K sector aligned virtual hard disk), which increases the performance. Why Windows Server 2012 Hyper-V VHDX 4K Alignment Is So Important
- Trim/Unmap – Space efficiency on VHDX files as well as the host disk
- Thin provisioning
- Ability to store custom metadata about the file that the user might want to record, such as operating system version or patches applied
You can convert a VHD into VHDX and vice versa. As long the size limit for the VHD is respected:
- Shutdown the Virtual Machine
- Double check if there is NO Snapshots
- Double check if there is NO replication enabled
- On the Hyper-V Manager, on the left pane select Edit Disk…
- Click on Next
- On the Edit Virtual Disk Wizard, type the name and location of your existing VHD file or click on Browse to locate
- Click on Next
- On the Choose Action page select Convert and then click Next
- On the Choose Disk Format page select VHDX and click Next
- On the Choose Disk Type page select Disk type : Fixed or Dynamic and then click Next
- On the Configure Disk page type the destination path and then click Next
- On the Summary page, click Finish to start the process. The process time depends on the VHD size.
