Context Before
To expand the scope of CMX, NVIDIA also launched STX. STX is a reference rack architecture using Nvidia’s BF-4 based storage solution to complement VR compute racks. The reference architecture effectively specifies exactly how many drives, Vera CPUs, BF-4 DPUs, CX-9 NICs, and Spectrum-X switches are needed for a given cluster.

Evidence
BF-4 in STX
Context After
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.
