The host servers and storage controllers can be connected to the switches using the QSFP+ and QSFP28
ports with appropriate breakout cables. The switches are interconnected to each other using 40GbE cables or
100GbE cables.
Optional steps are provided in section 3 to enable Data Center Bridging (DCB).
