## FAQs
### Q: What performance level did the Lenovo ThinkServer RD650, Xeon E5-2620v3 6C 2.4GHz, 10G Ethernet achieve on the TOP500?
A: The system achieved a sustained performance (Rmax) of 411.3 teraflops, placing it on the TOP500 list for three consecutive rankings from November 2015 through November 2016.

### Q: Which operating system does this ThinkServer RD650 configuration use?
A: It runs Linux, the open-source Unix-like operating system family first released in September 1991.

### Q: Who manufactures the ThinkServer RD650 with these specifications?
A: Lenovo, a Chinese multinational technology company established in 1984 and headquartered in Beijing, with 77,000 employees as of July 2023.

## Why It Matters
The RD650 configuration demonstrates how commodity server hardware can be aggregated into high-performance computing clusters capable of hundreds of teraflops. By combining Intel’s Haswell-EP architecture (Xeon E5-2620v3) with 10 GbE interconnects, Lenovo delivered a cost-effective building block for scale-out supercomputing. Its three-year presence on the TOP500 list shows sustained relevance in an industry where rankings usually shift dramatically each release. For enterprises, the same 2U chassis provides a bridge between traditional enterprise virtualization and HPC workloads, letting organizations re-use hardware for analytics, rendering, or scientific computing without specialized supercomputer procurement.

## Notable For
- Consistent 411.3 teraflops Rmax across three TOP500 publication cycles—rare stability in a rapidly changing list
- Achieves supercomputer-class performance using standard Intel Xeon E5-2620v3 processors rather than specialized accelerators
- 10 Gigabit Ethernet on board, allowing high-bandwidth clustering without additional adapter cards
- 2U rack density balances compute throughput and data-center space efficiency
- Linux-based, leveraging the open-source ecosystem for cluster management and scientific software stacks

## Body
### Hardware Configuration
The entry-level node pairs an Intel Xeon E5-2620v3 CPU with 10 GbE integrated networking. The E5-2620v3 is a six-core, twelve-thread part fabricated on Intel’s 22 nm process, introduced in Q3 2014 with a 2.4 GHz base clock and 3.2 GHz turbo frequency. The processor supports DDR4-1866 memory and provides 40 PCIe 3.0 lanes for expansion.

### TOP500 Context
System ID 178622 first appeared at position 411.3 teraflops Rmax and 560.0 teraflops Rpeak in November 2015. The same figures were reported in June 2016 and November 2016, indicating the cluster size and tuning remained static. No power or efficiency data were supplied to the list.

### Manufacturer Background
Lenovo Group Limited was founded in Beijing in 1984. By 2023 it employed approximately 77,000 people worldwide and operates in more than 60 countries. The company’s ThinkServer line, introduced after the 2014 IBM x86 acquisition, targets enterprise and HPC segments with rack, tower, and blade form factors.
