Folks, Not familiar with 3020 series at all. I see 4 nics (e0a, e0b, e0c,e0d) on the back of each head. Does it mean I have sacrifice one to be management and only 3 are available as data? Have NetApp change things? Or can I used all 4 in single/multi vips? I was going to do e0a and e0c in single A, e0b and and e0d in single B, and Multi VIP C on top of Sinlge A and Single B. Not sure what to do about management. Thanks for help
