Oracle has bought data centre fabric virtualisation start-up Xsigo for who knows how many bucks. Xsigo was founded in 2004, and its products connect servers and networked devices across an InfiniBand fabric based on I/O Director hardware. This is virtualised, so servers operate as if they have a normal, ordinary connection to a storage array or a network port. With I/O virtualisation, network connections can be dynamically moved between servers, removing cable clutter and making a server-storage-network system more responsive to events and better able to optimise its resources to respond to them.
