VM-to-VM (on the same host) via a hardware-based virtual switch in an SR-IOV network interface card (NIC). VMDq can provide a hardware assist when the hypervisor softswitch is involved, or you can use hypervisor bypass and SR-IOV to attach VMs directly to VFs (virtual functions). Note that there are trade-offs as a result.)

The only major things missing from their "Starter Kit" suite they offer are the addition of VMware - not cheap if you choose to purchase it - as well as the addition of a blade (or two) to serve as controllers of the system. The UCS Manager software bundled with the system provides core functionality (see diagram, right).

The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc. By integrating with VMware's Virtual Center, Xsigo provided a building block. This permits physically flatter networks.
