  • Clean air filters regularly to prevent dust buildup.

Power Requirements:

  • The 1200W redundant power supplies provide ample power.
  • Ensure the server rack has sufficient power capacity.
  • Monitor power consumption to identify potential issues.
  • Use power distribution units (PDUs) with monitoring capabilities. See Power Distribution

Storage Maintenance:

  • Regularly monitor the health of the NVMe SSDs using SMART data.
  • Implement a robust backup strategy to protect against data loss.
  • Consider using storage monitoring tools to proactively identify potential failures.

Networking Maintenance:

  • Monitor network traffic and latency.
  • Regularly update network drivers and firmware.
  • Implement network security best practices.

Software Maintenance:

  • Keep the operating system and all software packages up to date.
  • Regularly scan for vulnerabilities.
  • Implement a patch management system.

Component Monitoring:

  • Utilize IPMI to monitor server health, including CPU temperature, fan speed, and power supply status.
  • Implement a centralized monitoring system to track server performance and identify potential issues. See Server Monitoring.
  • Regularly check system logs for errors and warnings.

Long-Term Considerations:

  • Component obsolescence: Plan for component upgrades as newer technologies become available.
  • Cloud Provider Updates: Stay informed about changes to the cloud provider's infrastructure and services.
  • Cost Optimization: Continuously monitor cloud costs and adjust the server configuration as needed. See Cloud Cost Analysis.
