I want to have a web-scale virtual storage across multiples nodes. Nutanix's solution leverges principles in scale-out architecture from Google and components such as flash (including Fusion-io and SSD), delivering a building block architecture to modernize data centers. Compute and storage components in a single "hyperconverged" solution. It is datacenter in a box basically that removes the need for Network Storage by achieving what you need out of a SAN through super smart software But, I'm new with proxmox, maybe ProxMox to it as well as nutanix!
