Hyperconverged Infrastructure is definitely eating a lot of the traditional storage vendors lunches. Using Ubuntu with JuJu/Ceph/OpenStack all on the same servers provides plenty of power while reducing costs.

Even VMWare has come on board with vSAN which pushes out vendors like EMC/NetApp because you no longer need them when you can just create it against your existing hypervisors. Sure you can run one or two less VM's on it, but you have less cost overall.
