Network & Fiber

Switches, routers, transceivers, fiber and patch panels. Fabric topology and bandwidth set how the cluster scales, so match them to GPU count and east-west traffic.

Buying guide

Choosing equipment in Network & Fiber

Match fabric to GPU count, switch bandwidth and topology set how far the cluster can scale.

Count optics and trunks per link, transceivers and fiber add up quickly across an east-west fabric.

Standardize the optic, one OM4/SMF and connector standard simplifies spares and installs.

Watch oversubscription, size leaf and spine so east-west traffic is not bottlenecked.
