                                Antminer S21+ Description

                                The Bitmain Antminer S21 216TH is engineered for miners who need consistent, high-capacity SHA-256 performance in a stable and efficient package. With its 216 TH/s hashrate, the S21 delivers strong Bitcoin mining output while maintaining optimized energy consumption, making it suitable for a wide range of mining setups from mid-size operations to full-scale farms.

                                Its dual-fan air-cooled system is built for reliable 24/7 mining, provided the unit is installed in a clean, well-ventilated space with controlled ambient temperatures. The miner uses standard industrial power input and Ethernet connectivity, ensuring seamless integration into most existing infrastructures without the need for complex modifications.

                                The S21 series is recognized for its consistent hashrate performance, dependable thermal behavior, and durable construction, making it a strong option for miners upgrading from older S19 or early-generation S21 models.

                                Best For / Use Case

                                Small to mid-size mining farms needing stable output with manageable infrastructure
                                Farms wanting higher hash rate with manageable cooling/power needs

                                Strengths

                                Stable hashrate, easier deployment, lower heat/noise compared to higher output versions
                                Higher hashrate, better throughput per unit than 216TH, good efficiency

                                Considerations

                                Lower total throughput vs Pro
                                Slightly more power draw and heat vs 216TH, but offers higher performance

                                Notes
                                • (1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
                                • (2) Caution: Wrong input voltage may cause server damaged.
                                • (3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
                                • (4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
