calculate the bandwidth of your PCI bus/slot in Gb/s
        - you can only have one 4 Gb/s HBA working at 100% capacity on a PCI-X 
133 bus
        - 10 Gb/s ethernet requires PCI-X 266 or a suitable PCIe slot
calculate the bandwidth requirements of your drive
        - you can have maybe 2 or 3 high-speed drives per HBA
