Basically we should get ~24ish nodes like the nice ones in eqiad. The cluster will be smaller but we can't afford 31 of the nice nodes and its not a great choice anyway because then the secondary dc's cluster would be way overpowered. Start with what we budgeted and go from there. If you get a choice always put extra cash into nicer (but not larger!) SSDs. And RAM. Those are life. LIFE!
