Dell answer to HP Virtual Connect :SR-IOV

Dell has come up with solution partenring Citrix to virtualize I/O . They name this technology as SR-IOV (Single Root I/O Virtualization ).In this solution, instead of a hypervisor virtualizing an I/O device in the software and sharing that emulated virtual NIC with multiple VMs, a single I/O hardware itself is subdivided logically to appear as 128 virtual NICs. Each NIC is assigned independently and directly to a virtual machine to provide precise per-VM control for connection speed and quality of service.

In HP Virtual Connect , you basically control and divide LOM card on blade into 8 different nic and then it is presented to host . On host you create a virtual switch to share the nic.
