not even close .. we needed to hold 40 disks in 4U space (15TB per 4U)

	and avoid all the power cords  ( 8-10 vs 100 of um )
	( 1 nice (real) power supply per 5-10 motherboards )

	avoid all the heat... ( almost null compared to 1Us )

	avoid all the gazillion wires...  ( hard to avoid rats nest w/o
		putting a kvm and nic switch inside the 4U )

	quieter is better for working on the mess
