Hello Norman,

Thank you so much for your response, and that is an interesting setup.

How are these sprase file images initially built for each VM's virtual hdd? And
can this process be automated.

>> So life migration is possible, other than holding the VMs on local

I can understand that.

Good network engineering.

I guess also with this setup replication would be handled by rsync? If so, the
potential of this setup really starts to shine.

WOW, from NAS to SAN?


Kind Regards,

Nick.
