Customization

Evidence

For GB300, although the reference design has four ConnectX-8 NICs for the backend network and one Bluefield-3 for frontend network, most hyperscalers have their own design and alternative networking configurations, especially for Bluefield-3

Context After

For example, for some racks, even Amazon is deploying ConnectX-8 in GB300s in many cases. Also, most hyperscalers are deploying their in-house DPU instead of Bluefield-3 for frontend networking. The power delivery module and management modules in GB300 are also highly customized as every customer has differing preferences for these modules. As such, the front half of GB300 is highly customizable with each hyperscalers’ design differing from each other significantly.

② Atomic Claim

在 GB300 中，雖然 reference design 的 backend network 配置 4 顆 ConnectX-8 NICs、frontend network 配置 1 顆 Bluefield-3，但多數 hyperscalers 都有自研設計與替代 networking configurations，尤其是 Bluefield-3 部分。
