Context Before
Unlike the BF-4 in the VR NVL72, which consists of a Grace CPU and a single CX-9 NIC, the BF-4 in the STX reference design includes one Vera CPU, two CX-9 NICs, and two SOCAMM modules. Each STX box contains two BF-4 units, totaling two Vera CPUs, four CX-9 NICs, and four SOCAMM modules. For the whole STX rack, it has a total of 16 boxes, implying 32 Vera CPUs, 64 CX-9 NICs, and 64 SOCAMMs.

Context After
The STX announcement included a typical Nvidia show of strength where they named all major storage vendors as supporting STX, including AIC, Cloudian, DDN, Dell Technologies, Everpure, Hitachi Vantara, HPE, IBM, MinIO, NetApp, Nutanix, Supermicro, Quanta Cloud Technology (QCT), VAST Data and WEKA.
Put together, BlueField-4, CMX, and STX represent NVIDIA’s broader effort to standardize how clusters are designed at the storage layer. NVIDIA has captured the compute and network layer, and is actively moving into the storage, software, and infrastructure operations layers over time.
