Facebook's Second-Generation Modular Open Switch: Backpack

• mcpherrinm 10y ago
  Does anyone know what switching ASICs this uses? I'd guess https://www.broadcom.com/products/Switching/Data-Center/BCM56960-Series https://www.broadcom.com/products/Switching/Data-Center/BCM5... but I don't see anything for sure. Edit: https://code.facebook.com/posts/203733993317833/opening-designs-for-6-pack-and-wedge-100/ https://code.facebook.com/posts/203733993317833/opening-desi... says the Wedge 100 does use the Tomahawk, so it'll be the same in Backpack. The hardware looks a lot more sensible than 6-pack. The orthogonal connectors to vertical fabric cards is pretty similar an Arista 7324X or Cisco N9K. Good front-to-back airflow that way.

    They'll be contributing the design to Open Compute so, we'll find out soon if it's not already there.
