Context Before
CMX
CMX is NVIDIA’s context memory storage platform. CMX addresses a growing bottleneck in modern inference infrastructure: the rapid expansion of KV Cache required to support long-context and agentic workloads.
Evidence
At scale, on-device HBM does not have enough capacity
Context After
NVIDIA introduced a “new” intermediate storage “tier G3.5” within the inference memory hierarchy at CES in January. Tier G3.5 NVMe sits in between tier G3 DRAM and tier G4 shared storage (also NVMe, or SATA/SAS SSD, or HDD). Previously referred to as ICMS (Inference Context Memory Storage) and now branded as the CMX platform, this is just another re-brand of storage servers attached to compute servers via Bluefield NICs. The only difference from NVMe architectures is the swap from Connect-X NICs to Bluefield NICs.
② Atomic Claim
在大規模部署下，裝置上的 HBM 容量不足以容納全部資料。
