The new system, powered by Intel chips and small enough to fit in closets, comes as Lenovo works to close the deal for IBM's x86 server business.
Jen-Hsun Huang says the mobile chip, which was introduced at CES in January, is generating some interest from server makers.
The company has begun sampling its "Seattle" SoC, a key part of its "ambidextrous computing" effort.
The chip maker is looking to show the strength of the software ecosystem around heterogeneous computing processing.
Government officials reportedly are worried that buying servers from a Chinese company may endanger national security.
Advanced Micro Devices is progressing on its plans to move all of its North American data centers into a single 153,000-square-foot facility near Atlanta.
Lenovo looks to assure striking Chinese workers that the company will not slash wages or benefits once it takes over IBM's x86 server business.
IBM, which is selling its x86 server unit to Lenovo, saw large declines in both server revenue and shipments, the analyst firm says.
The high-end systems are designed to tackle data-intensive workloads like big data, business intelligence and analytics and to challenge RISC systems.
The group aims to extend the reach of IBM's Power architecture by licensing the chip design to companies for servers and storage systems.
Only those customers with systems under warranty will get access to firmware updates, which had been offered for free.
Company officials say they expect the microserver will help fuel the expansion of the ecosystem around ARM-based servers.
At the Open Compute Summit, the chip maker also unveiled a developer kit designed to encourage companies to build to the SoC.
