Hello Norman, Thank you so much for your response, and that is an interesting setup. we open up pools of up to 20 hosts which all mount the same NFS share which holds sparse file images as virtual hdds of the VM. How are these sprase file images initially built for each VM's virtual hdd? And

Hello Nick, the question is, what are you doing with it and why do you think you need a fibre channel SAN. Our goal indeed is to get rid of the SAN infrastructure as it is delicately to all kinds of failure with nearly zero fault tolerance. An example, you have an hicup or a power failure

Hello, I tend to disagree. A correctly designed SAN (using dual Fabric among other things) is a lot more stable and has a lot better performance than any NAS (NFS, CIFS, iSCSI) solution. One other thing that also needs to be correctly configured to have a stable SAN infrastructure is the
