Open Networking for Large-Scale Networks
Open Networking for Large-Scale NetworksLive session on Tuesday, May 9th 10:00 EDT
Most modern data centers are still using vendor-driven "future proof" routers and switches with offering lots of (often unnecessary) capabilities. To build large, however, it is often better to build simple—radically simple.
This webinar will cover the design components involved in building a data center or cloud fabric using a single, disaggregated device—the way some hyperscale and web scale operators build their networks. The first live session of the webinar will consider the benefits of disaggregated switch, focusing on the components, sources, and challenges in using disaggregated hardware and software in data center fabrics. The second live session will focus on the topologies and design concepts used in large scale data center fabrics using a single switching device as a leaf, spine and superspine switch.
- What is SDN
- What is white box
- What is disaggregation, and how is this different
Business drivers for disaggregation
- Single kind of control
- Reduce opex and capex
- Integrate the network better with the business architecture
- More flexibility around business changes, less of the network as a "thing that stands alone"
- Challenges to disaggregation
What pieces do you need to disaggregate?
- Network Operating System (NOS)
- Control plane
Who makes hardware?
- Chip vendor overview
- White box vendor overview
Who makes software?
- NOS options overview
- Routing stack overview
Why is the single SKU data center interesting?
- Reduced opex
- Reduced capex
- Troubleshooting simplicity
- Fixed delay
- Simplified optics
- Get rid of the chassis
Topologies for the single SKU data center
Getting rid of the chassis means externalizing the internal fabric into live optics, which means larger external fabrics — no more "two switches and you're done". While the leaf-and-spine topology is commonly used to build a data center fabric, we'll also cover Butterfly/Beneš topologies and their variants.
Challenges in the single SKU data center
- Optics and varying speeds
- Optical Cabling
- Power (more outlets, smaller draw)
