[Skunkworks] Network Attached Storage with Hyper Visor

Hi Guys i have an environment that i have implemented hyper visor running under windows 2008 R2, i have noticed it will be a fools errand(you can correct me) to keep increasing the hard disk space to accommodate the growing virtual hard disks , i would like to implement a NAS system which i can store the disks , any heads up on how i can smoothly do this? -- GG
