At VMworld 2012, VMware presented a Tech Preview of one of their latest ideas, which they termed “Distributed Storage”. So what exactly is this new technology? It is basically locally attached storage.
How is Distributed Storage new?
We know that VMware has allowed the use of local storage since inception; however, access to that storage was limited to the local host only, so it was only utilised for guests that were node-based, e.g., vShield appliances. To delve a little deeper you could use the analogy of a VSA (Virtual Storage Appliance), but unlike the VSA, which is a fully functioning virtual machine, this technology is actually part of the hypervisor.
