There can be some confusion regarding VT-d support on specific processors. Some pages show the Intel® Xeon® Processor 5500 series explicitly support VT-d but the information is missing from the Intel® Xeon® Processor 5600 series.
VT-d is not a feature of the processor itself but rather a feature of the Chipset. As long as the chipset/BIOS combination support VT-d and the processor support VT, there will be VT-d support.
For more information, please check the Chipset datasheet:www.intel.com/content/www/us/en/chipsets/server-chipsets/server-chipset-5500.html
