Switch and Server Front to Back Air Flow 3D model

This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 Model shows switch and server air flow characteristics. One wonders why switch manufacturers go to all the trouble to make their 24-48 port devices only 1 Ru high when in operations you have to give up a minimum of 1 Ru for cable management and another 1 Ru so the switch can pull air in over the top and down to the inlets on the side of the switch. Adding insult to injury 99% of the servers have their Ethernet ports on the hot aisle side.. and 99% of the switches have their Ethernet ports on the cold aisle side.. so besides the air flow mismatch you also have to run around the entire row of cabinets just to visually verify link state when installing or moving equipment.
