That motherboard has 1 PATA port, 7 SATA ports and 1 e.SATA port. Only some server motherboards include SAS ports.
You can buy a SATA/SAS controller or buy a X58 chipset based motherboard that includes a SAS controller, e.g., Asus P6T Deluxe (requires a Core i7 CPU).
You can buy an inexpensive controller like the PROMISE FastTrak TX2650 PCI Express SATA / SAS Controller Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16816102139, but read the reviews and make sure that your motherboard is supported.
You can buy a somewhat better controller like the HighPoint RocketRAID2640X4 PCI-Express x4 SATA / SAS Controller Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16816115050. Again read the reviews, including Tom's review.
And at over $200, you can get a better controller, e.g, the Adaptec 2260100-R PCI Express SATA / SAS Controller
