Intel C612

The C612 provides a fixed set of lanes directly from the PCH (not to be confused with CPU PCIe lanes).

The chipset supports Intel® Virtualization Technology for Directed I/O (VT-d). This is critical for modern data centers, as it allows direct hardware assignment of peripherals (like NICs or storage controllers) to specific Virtual Machines (VMs). This reduces virtualization overhead and improves I/O performance in cloud computing environments. intel c612
