Yes the onboard NIC of S5000VSA does support teaming. If you're running Windows, you can download the http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18807&ProdId=2487 latest driver which includes Intel PROSet. Install by running the .bat file. If you're running Linux then you should use the bond service included in Linux, No separate utility is required.
