Context Before

Evidence

The midplane acts as a bridge for the PCIe signal between the two Strata modules and the modules at the front of the chassis.

Context After

The midplane module is vertically placed across the middle of the chassis with Paladin HD2 board-to-board connector on both sides of the module. Strata modules connect to one side of the midplane while the Orchid modules, the BlueField-4 module, the PDB module, and the management modules connects to the other side.

② Atomic Claim

midplane 作為 PCIe signal bridge，連接兩個 Strata modules 與 chassis 前方的 modules。
