*All* Pegasos 2 have GbE. I think he refered to the fact that the Discovery II MV64361 has indeed *two* on-chip GbE controllers.
But instead of just adding a second GbE connector one could also substitute the MV64361 for the MV64360, which has not just three GbE controllers but also 64 bit PCI(-X) instead of 32 bit ones, or even better -- as already suggested by the thread opener -- take a newer Discovery (III, LT, V, VI) :-)
