Context Before

Evidence

The BlueField-4 DPU sits in center of the front of the chassis between the left-side Orchid module and the management module.

Context After

BlueField-4 is made up of a Grace CPU and a CX-9 NIC. The module also comes with 128GByte of on board LPDDR5x, 512Gbyte of on board pluggable SSD and an integrated AST2600 BMC from Aspeed. In the reference design of the VR NVL72 compute tray, BlueField-4 acts as a DPU providing up to 800Gb/s of front end networking capability.

② Atomic Claim

BlueField-4 DPU 位於 chassis 前方中央，在左側 Orchid module 與 management module 之間。
