This morning Oracle announced the acquisition of Xsigo Systems and there has been a frenzy of media coverage around it, primarily because it follows VMware’s acquisition of Nicira, creating speculation of future acquisitions and many implications to the future of IT. However, some of the positioning of this acquisition was just flat out wrong.
I first want to dispel some of the myths about what Xsigo does and the type of vendor it is. I’ve seen it compared to other SDN vendors, such as Nicira and Big Switch, but Xsigo is not an SDN vendor. From a very high level I would agree that Xsigo creates virtual network connections through software, so I guess it may be technically correct, but it isn’t an OpenFlow-based software controller that can automate the configuration of network changes, which is what “SDN”s have largely become. Xsigo is virtual I/O. The company sits between servers, storage and network infrastructure and virtualizes I/O connections, and does a great job of it.
