Reducing Costs With Daisy Chaining

Reducing Costs With Daisy Chaining

Say you spend $20,000 on a network switch that has 48 IP ports. This means each port costs around $416. In a traditional daisy chaining setup, each intelligent PDU requires 1 switch per port which equals about $832 per rack (this is not including the cost for cabling). 

This is where next-gen network daisy-chaining comes into the picture, which is made possible through Rapid Spanning Tree Protocol. In this setup up to 40 PDUs can be connected via Ethernet cable to one another in a series, or chain. With daisy chaining, 40 PDUs only use 2 network ports (combined $832$). Assuming 2 PDUs per rack, this means you can provide intelligent power for 20 racks for the same network cost it historically took to bestow intelligent power on one rack. Per-rack TCO for smart power is now about $41 per rack. Scale this across your entrie facility, and the savings easily add up into the thousands. 

Reducing costs by daisy chaining could be the difference between spending $832 per rack, and $41 per rack. Which would you prefer?
