Bryan and Justin always crank out great looking stuff, so the systems guys try to keep up.
Red and orange run out to storage switches.
Black is the dark, private interconnects between servers.
Blue is out to the public like water flowing.
White is for remote ALOM and goes to the console servers, like a the archetypal knight in white shining armor.
Green which don’t see is used for the interconnecting and meshing the switches themselves. What’s green mean to you?
