EMC and VMware have a bit of an overlap when it comes to their software defined storage products. VMware offers VSAN while EMC offers ScaleIO. However, it looks like there’s going to be a bit more cooperation here as ScaleIO will be offered as a kernel module on ESXi servers. Which begs the question: does this mean VMware won’t be closing up their kernel to third party vendors? Of course, I’m not sure EMC truly counts as a third party vendor, but that would be good news for customers!
