Appliance Hardware

Netflix continues to evolve our appliance hardware capabilities to help ISPs most efficiently deliver high-quality Netflix traffic with a focus on localization. We tailor deployment and hardware architectures for each ISP that we work with. Our Open Connect Appliances are based on commodity PC components, assembled in custom cases by our suppliers.

We have several types of appliances, designed to meet our global deployment requirements. High level specifications are provided here. If you need detailed specifications for a particular revision of an Open Connect Appliance, contact your Partner Engagement Manager.

Storage appliances

Storage appliances are 2U servers that are focused on reliable dense storage and cost effective throughput. This appliance is used to hold the Netflix catalog in many IX locations around the world and embedded at our larger ISP partner locations.

Storage appliance focus areas

  • Large storage capacity
  • 2U for rack efficiency (no deeper than 29 inches)
  • Enough low cost NAND to reach 10GB/s of throughput (<0.3 DWPD)
  • Network flexibility to connect at 6x10GE LAG or 1x100GE
  • 2 and 4 post racking
  • AC or DC power
  • Single processor
