Monero Těžební Výpočetní Cluster – 20× Supermicro Dual Xeon Blade Uzlů

Overview

This compute cluster is purpose-built for high-throughput Monero (XMR) mining using the RandomX algorithm. Engineered with twenty Supermicro SBI-421E-1T3N blade servers, each equipped with dual Intel Xeon Silver 4516Y+ processors, the system delivers consistent, scalable CPU mining performance with enterprise-grade reliability and management capabilities.

The cluster is housed in a Supermicro SBE-820J2-630 4U blade enclosure, featuring integrated 25G networking, centralized power delivery, and remote chassis management. Designed for institutional mining, on-prem cryptographic compute infrastructure, or remote-hosted deployment.

Compute Architecture

Per Node Configuration:

• 2× Intel Xeon Silver 4516Y+ (Sapphire Rapids-SP, 24 threads each)

• Total of 48 logical threads per node

• 4× 16GB DDR5-4800 ECC REG DIMMs (64 GB per node)

• 1× 480 GB Micron 7450 PRO Enterprise NVMe SSD

• Dedicated IPMI management interface

Cluster Totals:

• 960 logical threads across 20 nodes

• 1.28 TB of DDR5 ECC memory

• 20× NVMe storage volumes (enterprise-grade)

• Centralized 25G Ethernet switching

• Redundant high-efficiency power supplies

Mining Performance

Each blade is optimized for RandomX mining and tuned for multi-threaded, NUMA-aware operation using XMRig with large page support, static CPU affinity, and performance governor settings.

• Estimated performance per node: 9,500–10,000 H/s

• Total cluster hashrate: ~190,000–200,000 H/s

• RandomX optimization includes AVX2 acceleration, cache tuning, and memory prefetching

Cluster performance may vary depending on ambient conditions, tuning parameters, and pool selection.
