Radeck, To avoid blocked ports, you will need to configure your upstream links as follows;
Built a port-channel from SW13 to SW11/12. Build a port-channel from SW14 to SW11/12. Physically, SW 11 and 12 looks as 2 x Switches but logically, SW 13 and 14 treats SW11/12 as a single switch. I suggest using at least 2 x 10GE ports between SW13 & 14 as SFP's do fail from time to time. You can use MGM for peer link keep alive or a dedicated link. You can increase your port-channel capacity as your traffic grows.
