Supermicro announced its NVIDIA Vera CPU Rack on October 22, 2026: a fully liquid-cooled, CPU-only system designed for agentic AI, reinforcement learning and data processing. The company says the rack is available to quote, but no shipping date is provided in the available coverage. 5

The system’s headline figure is up to 22,500 concurrent agent sandboxes. That is Supermicro’s stated capacity, not independent proof of performance on customer workloads; real-world testing will be needed to assess how it performs in production. 7

What’s inside the 48U Vera rack
The 48U rack houses 256 NVIDIA Vera CPUs across 32 liquid-cooled 1U compute trays, with four nodes per tray. The stated total is 22,528 CPU cores and 45,056 threads. 7
44
Supermicro’s datasheet lists up to 400 TB of SOCAMM2 LPDDR5X memory and up to 300 TB/s of aggregate memory bandwidth per rack. These are maximum system specifications, not a measure of performance for every workload. 44
Agent sandboxes and safety controls
A sandbox is an isolated environment where an AI agent can carry out tasks. Supermicro says the rack can support as many as 22,500 of them at once. That number should be read as a vendor capacity claim: the available evidence does not include independent workload testing that would establish how many sandboxes a particular deployment can sustain. 7
19
The announced design integrates NVIDIA BlueField-4 data processing units with the NVIDIA Open Agent Safety Platform and OpenShell reference architecture. Supermicro describes these components as supporting agent orchestration, monitoring and policy enforcement; their inclusion does not by itself demonstrate safety or effectiveness in a given deployment. 6
17
Power options and how it fits with Vera Rubin
The CPU rack can be deployed as a standalone system or alongside Supermicro’s Vera Rubin NVL72 GPU racks. The announcement presents the CPU rack as dedicated CPU capacity that complements the GPU platform, rather than as a replacement for it. 6
9
The listed power configurations include traditional AC and an optional 800 VDC sidecar power rack that supports battery backup units. 17 The available sources do not establish how a customer’s facility would need to be configured for either option.
What the announcement does—and doesn’t—establish
The announcement lays out a high-density CPU system with substantial advertised memory and agent-sandbox capacity. But “available to quote” is not the same as shipping, and the quoted sandbox figure is not independent validation of performance under specific workloads. 7
19
For buyers, the practical questions are therefore still deployment-specific: when systems will ship, what configurations will be offered, and how the rack performs on the intended agent, reinforcement-learning or data-processing tasks. The cited materials provide product specifications and vendor claims, not answers to those workload-level questions.
