- Manufactured by Lenovo, the Beijing-based technology company founded in 1984
- Runs Linux, the Unix-like OS first released 17 September 1991
- Each node carries a 16-core Intel Xeon E5-2683 v4 processor running at 2.1 GHz
- Factory-equipped with 10 Gigabit Ethernet networking
- Classified in Wikidata as both a “supercomputer” and a Lenovo product
- Lenovo employed roughly 77 000 people worldwide as of July 2023

## FAQs
### Q: What operating system does the ThinkServer RD350G use?
A: It ships with and is benchmarked under Linux, giving users open-source drivers and cluster toolchains out of the box.

### Q: How fast is the system in comparative terms?
A: The RD350G delivered 621.9 teraflops on the LINPACK benchmark, placing it on the November 2017 TOP500 list of the world’s most powerful supercomputers.

### Q: Which network interface comes standard?
A: Every chassis includes 10 Gigabit Ethernet ports for low-latency, high-bandwidth cluster communication without add-in cards.

## Why It Matters
For research groups or enterprises that need HPC capability but cannot fund a bespoke build, the RD350G offers an off-the-shelf path to hundreds of teraflops. Lenovo packaged datacenter-grade cooling, power, and 10 GbE into a 2U rack form-factor, so labs can scale out nodes without exotic interconnects. Its November 2017 TOP500 entry validated that commodity Xeon parts, Linux, and Lenovo integration can crack the petascale barrier, broadening access to supercomputing for universities and smaller cloud providers. Because the system is Linux-based, users avoid vendor lock-in and can re-compile open-source science codes immediately. In short, the RD350G democratized serious compute performance: you could order a rack, plug in 10 Gb cables, and join the global supercomputing club.

## Notable For
- One of the first Lenovo-branded systems to surpass 600 teraflops using mainstream Xeon E5 v4 silicon
- Ships with integrated 10 GbE, eliminating the cost and slot consumption of separate adapters
- Certified Linux compatibility means every major cluster distribution (Rocks, CentOS, Ubuntu Server) installs without custom drivers
- 2U rack height keeps density high while leaving neighboring racks free for storage or accelerator nodes
