Bare Metal Deployment

When deploying RustFS on bare metal servers, you can maximize hardware performance and achieve the best storage efficiency. This guide covers bare metal deployment best practices.

Hardware Requirements

Minimum Configuration

• CPU: 4 cores, 2.4GHz or higher
• Memory: 8GB RAM minimum, 16GB recommended
• Storage: At least 4 drives for erasure coding
• Network: Gigabit Ethernet

Recommended Configuration

• CPU: 16+ cores, 3.0GHz or higher
• Memory: 32GB+ RAM
• Storage: 8+ drives, mixed SSD/HDD for tiering
• Network: 10Gb Ethernet or higher

Deployment Architecture

Single Node Mode (SNSD)

Suitable for development and testing environments:

# Single node with single drive
rustfs server /data --console-address ":9001"

Multi-Node Mode (MNMD)

Recommended for production environments:

# Node 1
rustfs server http://server{1...4}/data{1...4} \
  --console-address ":9001"

# Node 2-4 (similar configuration)

Performance Optimization

Storage Configuration

1. Drive Selection

   • Use enterprise-grade drives for production
   • Consider NVMe SSDs for high-performance workloads
   • Separate OS and data drives

2. RAID Configuration

   • Disable hardware RAID for object storage
   • Use JBOD (Just a Bunch of Disks) mode
   • Let RustFS handle redundancy

Network Optimization

1. Network Bonding

   # Configure network bonding for redundancy
   sudo modprobe bonding
   echo "balance-rr" > /sys/class/net/bond0/bonding/mode

2. Jumbo Frames

   # Enable jumbo frames for better throughput
   sudo ip link set dev eth0 mtu 9000

Monitoring and Maintenance

Health Monitoring

• Monitor drive health with SMART tools
• Track network utilization and latency
• Set up alerts for hardware failures

Maintenance Procedures

1. Drive Replacement

   • Hot-swap failed drives
   • Monitor healing process
   • Verify data integrity

2. Node Maintenance

   • Graceful node shutdown
   • Rolling updates
   • Capacity planning

Security Considerations

Physical Security

• Secure server room access
• Environmental monitoring
• Power redundancy

Network Security

• Firewall configuration
• Network segmentation
• TLS encryption for client connections

Troubleshooting

Common Issues

1. Drive Failures

   • Check SMART status
   • Replace failed drives promptly
   • Monitor healing progress

2. Network Issues

   • Verify network connectivity
   • Check bandwidth utilization
   • Monitor for packet loss

3. Performance Issues

   • Analyze I/O patterns
   • Check for CPU/memory bottlenecks
   • Optimize drive layout
