Episode notes
AI Traffic Is Fundamentally Different
- AI traffic patterns differ fundamentally from cloud front-end traffic with extreme burstiness and intensity.
- Ullal explains AI back-end networks require new metrics and architectures beyond traditional TCP/IP assumptions.
Power Is The New Bottleneck
- Power, not hardware, has become the dominant constraint for large AI data centers.
- Ullal notes modern AI sites consume orders of magnitude more power, moving discussions from megawatts to gigawatts per facility.
Joining Arista At Zero Revenue
- Ullal joined Arista when it had zero revenue and about 30 engineers during the 2008 financial collapse.
- She stayed because she loved working with engineers and believed in the founders' technical vision.
