Windows 2012 R2 - Hyper-V - Allocation Unit Size for Hyper-V

Hi ,

I am building up Windows Server 2012 R2 cluster.

Its a 5 node cluster with 3 TB x 5 CSV Disks.

I dont see any specific recommendation for Windows 2012 R2 - Hyper-V - Allocation Unit Size for Hyper-V.

Is "default" allocation unit which I get on Format Disk page is appropriate for Hyper-V ? To my understanding, its the OS default and will take 4 K. Any thoughts or recommendation ?
