Context Before

Lastly, the BlueField-4 DPU is able to control the 8 ConnectX-9 backend NICs allowing for unified management of both front end north-south network & back end high speed East-West networks. This system, known as Advanced Secure Trusted Resource Architecture (Astra), thus takes the provisioning and monitoring load off of the host CPU.

Evidence

The only issue with this is that BlueField-4 is expensive, so we expect most hyperscale customers to deploy their in-house DPU solutions instead.

Context After

② Atomic Claim

問題在於 BlueField-4 成本高，因此 SemiAnalysis 預期多數 hyperscale customers 會改用自家的 DPU solutions。
