13 Hyper-V Cluster Shared Volume Tips & Tricks
Things to consider when setting up cluster shared volume backup tasks using Hyper-V backup software:
- Don’t use file based methods (such as backing up files directly). Use the Hyper-V backup function instead
- Don’t run backups on several nodes at the same time or you’ll get errors (Windows Server 2008 R2, this has been improved by Microsoft in Windows Server 2012)
- Don’t spread VHD, AVHD, AVHDX, and VHDX files across several cluster volumes. A big no-no. This won’t work. All files need to be in one volume
- Don’t involve more than one volume. All VM files including its config files have to be stored on the same volume
- Don’t select several VM for concurrent backup if they are located on different volumes
- Isolate backup traffic from cluster management traffic. This is extremely important
- Use separate NICs and switches to isolate traffic from cluster management traffic
- Use Jumbo packets
- Install at least 1 GBPS Ethernet or faster
- Don’t install too many nodes on the same bus
- Use fixed sized VHDs, not dynamically expanding
- Do not use Hyper-V snapshots. They tremendously impact performance
- Use 64 KB cluster size for NTFS inside VMs as well as on the host volume to reduce overhead
