For us storage types, one of the more interesting announcements coming out of VMworld is VSAN (formal name "Virtual SAN"), which will now be available in beta form before too long.
Although VSAN does many of things a traditional storage array does, it's not a traditional storage array: it's a software-based storage array that uses clusters of commodity server hardware to do its work. Storage and compute workloads run together on the exact same resource pool.
Yes, it's a v1 product in many regards (that's to be expected!) but there are some great ideas to be found in what the team has done -- worthy of deeper understanding -- as I'm sure we'll see more of these newer concepts going forward.
