Context Before
As we noted in mid-January in our Memory Model note ↗, Nvidia’s ICMS inserts a new G3.5 tier between local SSD (G3) and shared storage (G4), optimized specifically for ephemeral, recomputable KV cache. The ICMS requires a dedicated networking layer designed exclusively for KV traffic. Wherever networking is used in this architecture, it is provisioned as a context memory network — isolated from general data movement and optimized for predictable decode latency.
The challenge with this is that the volumes of SSDs going to ICMS / CMX are quite overblown by the industry. We worked through the math in the Memory model ↗ and Tokenomics model ↗.
Evidence
In a preferred DGX-style configuration, a single BlueField-4 per tray may serve four Rubin processors, with the DPU dedicated purely to KV cache traffic and not shared with generic storage I/O
Context After
The new CMX/ICMS ecosystem will likely include leading storage providers such as Weka, DDN, Dell Technologies, NetApp, VAST Data, and others.

② Atomic Claim
在偏好的 DGX-style configuration 中，每 tray 可配置 1 顆 BlueField-4 服務 4 顆 Rubin processors，且 DPU 專門處理 KV cache traffic，不與一般 storage I/O 共用。
