Context Before

Each LPX compute tray or node has 16 LPUs with 2 Altera FPGAs, 1 Intel Granite Rapids host CPU and 1 BlueField-4 front-end module. As with other Nvidia systems, hyperscalers customers can and

Evidence

will use their own Front-end NIC of choice rather than paying for Nvidia’s BlueField.

Context After

The LPU modules are mounted in a belly-to-belly on the PCB, meaning 8 LP30 modules on the top side of the PCB and the other 8 LP30 modules on the bottom. All of the connectivity that comes out of the LPU are via PCB traces and given the dense all-to-all mesh for intra-node connections this requires a very high spec PCB to support the routing. The belly-to-belly mounting is used to reduce PCB trace lengths across the ‘X’ and ‘Y’ dimensions.

② Atomic Claim

會使用自己選擇的 Front-end NIC，而不是支付 Nvidia 的 BlueField。
