On the heals of VMware buying Nicira for software defined networking (SDN) or what is also known as IO virtualization (IOV) and virtualized networking, Oracle is now claiming their own SDN capabilities with their announcement of intent to acquire Xsigo. Founded in 2004, Xsigo has a hardware platform combined with software to enable attachment of servers to different Fibre Channel (SAN) and Ethernet based (LAN) networks with their version of IOV.
