  1. Chia Blockchain Server Configuration - Detailed Technical Documentation

This document provides a comprehensive technical overview of a server configuration optimized for Chia Blockchain farming. It details hardware specifications, performance characteristics, recommended use cases, comparisons with alternative configurations, and essential maintenance considerations. This documentation is intended for experienced server administrators and hardware engineers.

1. Hardware Specifications

Chia farming is uniquely demanding, prioritizing high-throughput, low-latency storage over raw processing power. The key component is not the CPU or GPU, but the speed and endurance of the storage system. This section details the recommended specifications for a dedicated Chia farming server.

1.1. CPU

While Chia farming is not CPU-intensive, a capable CPU is still needed for plot creation, managing the blockchain, and handling network operations.

  • **Model:** AMD Ryzen 9 5900X or Intel Core i9-10900K (or equivalent generation/performance)
  • **Cores/Threads:** Minimum 12 cores / 24 threads. More cores can modestly accelerate plot creation.
  • **Base Clock:** 3.7 GHz or higher
  • **Boost Clock:** 4.8 GHz or higher
  • **TDP:** 105W - 125W (consider cooling requirements – see section 5)
  • **Instruction Set:** AVX2 support is essential for optimal plot creation speed. See CPU Instruction Sets for more detail.

1.2. RAM

Sufficient RAM is crucial for plot creation and efficient blockchain operation.

  • **Capacity:** 64GB minimum, 128GB recommended for larger farms.
  • **Type:** DDR4 ECC Registered RAM is *highly* recommended for data integrity. See Memory Technologies for ECC details.
  • **Speed:** 3200MHz or higher. Faster RAM can marginally improve plot creation times.
  • **Configuration:** Quad-channel configuration is preferred for optimal bandwidth.
  • **Latency:** CL16 or lower.

1.3. Storage

This is the most critical component of a Chia farming server. The focus is on high-endurance, high-throughput SSDs.

  • **Plotting SSDs (Temporary):**
   *   **Type:** NVMe PCIe Gen 4 SSDs are *essential* for reasonable plot creation times.  See NVMe SSD Technology for an in-depth explanation.
   *   **Capacity:** 1TB - 4TB per drive. Multiple drives can be used in parallel to accelerate plotting.
   *   **TBW (Terabytes Written):**  Minimum 1600TBW. Higher TBW significantly extends drive lifespan.  See SSD Endurance and TBW
   *   **Sequential Write Speed:** 5000 MB/s or higher sustained write speed.
   *   **Interface:** PCIe 4.0 x4
   *   **Example Models:** Samsung 980 Pro, Western Digital Black SN850, Sabrent Rocket 4 Plus.
  • **Farming SSDs (Permanent):**
   *   **Type:** NVMe PCIe Gen 3 or Gen 4 SSDs. While Gen 4 is preferred, Gen 3 can be acceptable with careful consideration of TBW.
   *   **Capacity:** 1TB - 8TB per drive, depending on farm size.
   *   **TBW:** Minimum 800TBW. Again, prioritize endurance.
   *   **Sequential Read Speed:** 3000 MB/s or higher. Read speed is more important than write speed for farming.
   *   **Interface:** PCIe 3.0 or 4.0 x4
   *   **Example Models:** Crucial P5 Plus, Kingston KC3000, SK Hynix Gold P31.
  • **RAID Configuration:** RAID 0 is commonly used for performance, but presents a higher risk of data loss. RAID 10 offers a balance of performance and redundancy. See RAID Configurations for detailed explanations. *Do not use hardware RAID controllers; software RAID is preferred.*

1.4. Networking

A stable and reliable network connection is essential for participating in the Chia blockchain.

  • **Interface:** Gigabit Ethernet (GbE) is the minimum requirement.
  • **10 GbE:** Recommended for larger farms or if network congestion is a concern. See Networking Fundamentals for more detail.
  • **Redundancy:** Consider link aggregation or multiple network interfaces for redundancy.

1.5. Power Supply

A high-quality, reliable power supply is crucial for system stability.

  • **Wattage:** 850W - 1200W, depending on the number of drives and other components.
  • **Certification:** 80+ Gold or Platinum certified for efficiency.
  • **Protection Features:** Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP).

1.6. Motherboard

  • **Chipset:** AMD X570 or Intel Z590 (or equivalent).
  • **PCIe Slots:** Multiple PCIe x4 slots are *required* for connecting NVMe SSDs.
  • **RAM Slots:** Support for at least 128GB of RAM.
  • **Networking:** Integrated Gigabit Ethernet. Consider a motherboard with 10GbE support if desired.

2. Performance Characteristics

The performance of a Chia farming server is primarily determined by its storage system.

2.1. Plot Creation

  • **Plot Size:** Typically 2TiB (Terabytes) or 3TiB.
  • **Plot Creation Time (Ryzen 9 5900X, 64GB RAM, Samsung 980 Pro 2TB):** Approximately 6-8 hours per 2TiB plot. Faster SSDs and more RAM can reduce this time.
  • **Plot Creation Time (Intel i9-10900K, 64GB RAM, WD Black SN850 2TB):** Approximately 7-9 hours per 2TiB plot.

2.2. Farming Performance

  • **Time to Win:** Highly variable, dependent on netspace size and farm size.
  • **Expected Win Rate:** Determined by the proportion of netspace controlled by the farm.
  • **SSD Read Latency:** Lower latency directly translates to faster challenge solving.
  • **Network Throughput:** Maintaining a stable connection is key to quickly responding to challenges.
Scenario Plot Size Approximate Plotting Time (Hours) Notes
High-End (R9 5900X, 128GB RAM, Samsung 980 Pro) 2TiB 5-6 Optimal configuration for fastest plotting.
Mid-Range (R7 5800X, 64GB RAM, WD Black SN850) 2TiB 7-8 Good balance of performance and cost.
Budget (R5 5600X, 64GB RAM, Crucial P5 Plus) 2TiB 9-12 Acceptable for smaller farms, but plotting will be slower.

3. Recommended Use Cases

  • **Dedicated Chia Farming:** This configuration is ideal for individuals or businesses looking to actively farm Chia and earn rewards.
  • **Large-Scale Farms:** Scaling this configuration with multiple servers is suitable for building large, competitive farms.
  • **Data Storage with Chia Farming as a Secondary Function:** The high-performance SSDs can also be used for other data-intensive applications when not actively farming.
  • **Proof-of-Space Testing and Development:** Useful for developers working on Chia-related projects or testing new farming strategies.

5. Maintenance Considerations

Maintaining a Chia farming server requires careful attention to cooling, power, and data integrity.

5.1. Cooling

  • **CPU Cooler:** A high-performance air cooler or liquid cooler is essential to prevent thermal throttling. See CPU Cooling Solutions.
  • **SSD Cooling:** NVMe SSDs can generate significant heat under sustained load. Consider using heatsinks or fans to keep them cool. Thermal throttling can severely impact plotting and farming performance.
  • **Case Airflow:** Ensure adequate airflow within the server chassis to remove heat.

5.2. Power Requirements

  • **Dedicated Circuit:** The server should be connected to a dedicated electrical circuit to avoid overloading.
  • **UPS (Uninterruptible Power Supply):** A UPS is *highly* recommended to protect against power outages and ensure data integrity. See UPS Systems
  • **Power Consumption Monitoring:** Monitor power consumption to ensure the power supply is adequately sized and to identify potential issues.

5.3. Data Integrity

  • **Regular Backups:** Back up plot data to a separate storage location to protect against data loss. While RAID offers redundancy, it is *not* a substitute for backups.
  • **SMART Monitoring:** Regularly monitor the SMART attributes of the SSDs to detect potential failures.
  • **File System Checks:** Periodically run file system checks to ensure data integrity.
  • **Drive Health Monitoring:** Utilize software tools to actively monitor SSD health and performance.

5.4. Software Maintenance

  • **Chia Blockchain Software Updates:** Keep the Chia blockchain software up to date to benefit from bug fixes and performance improvements.
  • **Operating System Updates:** Regularly update the operating system with security patches and bug fixes.
