Netflix Open Connect Content Delivery Network

Around the world, people are enjoying nearly a billion hours per month of movies and TV shows from Netflix. Now, Netflix is enabling ISPs to get Netflix video data directly from Open Connect, a single-purpose content delivery network we've established.

Most of you want to see the HW.


When designing the Open Connect Appliance Hardware, we focused on these fundamental design goals:

  • Very high storage density without sacrificing space and power efficiency. Our target was fitting 100 terabytes into a 4u chassis that is less than 2' deep.
  • High throughput: 10 Gbps throughput via an optical network connection.
  • Very low field maintenance: the appliance must tolerate a variety of hardware failures including hard drives, network optics, and power supply units.
  • Simple racking and installation. Front mounted power and network ports are the only things to connect at install time.
  • NewImage

 Here is the BOM for the HW.
