Taking this even further, options like the hadoop fat twin nodes with 12 drives in 1U potentially could be even denser, while spreading the drives out over even more nodes. Now instead of 4-5 large dense nodes you have maybe 35-40 small dense nodes. The downside here though is that the cost may be a bit higher and you have to slide out a whole node to swap drives, though Ceph is more tolerant of this than many distributed systems.
Another one is 35-40 switch ports vs 4-5. I hear "regular" 10G ports eat up over 10 watts of juice and cat6e cable offers a unique combination of poor design and high cost. It's probably ok to need 35-40 routable ip addresses: you can add another interface & subnet to your public-facing clients.
