Recommendations for base disk cluster size for hosting Hyper-V Virtual Machines?

-

has done investigation interdependencies between cluster , offset of disk hosting hyper-v vm , cluster , offset of virtual disk on 1 of vm's? 

i guess poorly formatted disk going translate bad performance on virtual disks hosted on lun; how close dependency going be?  should match (ideal)?  there issue if plan large (128kb) cluster size on base disk and utilize vm's have cluster sizes of 32kb or 64kb?

i'm concerned how high i/o applications exchange , sql tuned disk perspective in hyper-v environments leads question of how base disk formatted.  since we're planning our first internal hyper-v demo environment thought auspicious time pose question.

thanks,

went through bit of hand-wringing when choosing cluster , stripe size hyper-v test machine - similar setup mentioning - high-end desktop hardware, , in case im using 4x320gib satas in raid10 configuration guest machines. in end, kept default ntfs cluster (4k) and raid stripe sizes (64k), after reading documentation intended vmware. unfortuntely i've lost links, vmware users did pretty thorough testing different configurations , saw no real benefit alternate configurations. might larger cluster size beneficial since you're dealing large files (vhds), since io on these isnt large sequential reads/writes, instead normal varied activity see elsewhere, larger clusters have no benefit.
