5. Maintenance Considerations
Maintaining the CMS server requires adherence to specific guidelines to ensure optimal performance and reliability.
Cooling:
- The server chassis is equipped with redundant hot-swappable fans. Regularly check fan status and replace any failing fans promptly.
- Ensure adequate airflow in the server room. The recommended operating temperature is between 20°C and 25°C (68°F and 77°F). See Internal Document: Data Center Cooling Best Practices.
- Monitor CPU and hard drive temperatures using monitoring tools.
Power Requirements:
- The server requires a dedicated 208V/240V power circuit.
- Ensure that the power circuit is capable of providing at least 10 amps.
- Regularly check the power supply units (PSUs) for proper operation.
Storage Maintenance:
- Regularly monitor disk health using SMART monitoring tools. Replace any failing hard drives proactively.
- Perform periodic filesystem checks to ensure data integrity.
- Implement a robust backup and disaster recovery plan. See Internal Document: Backup and Disaster Recovery Plan.
- Consider implementing data lifecycle management policies to archive or delete old configuration data.
Network Maintenance:
- Regularly update network drivers and firmware.
- Monitor network performance and troubleshoot any connectivity issues.
- Implement network security measures to protect the server from unauthorized access. See Internal Document: Network Security Guidelines.
Software Maintenance:
- Keep the operating system and configuration management software up to date with the latest security patches and bug fixes.
- Regularly review and optimize configuration management playbooks and code.
- Implement a version control system to track changes to configuration files.
Physical Security:
- Secure the server room with appropriate physical access controls.
- Implement environmental monitoring to detect and respond to potential threats such as fire, flood, or temperature extremes.
Predictive Failure Analysis:
- Utilize server management tools that offer predictive failure analysis for components like hard drives and power supplies. This allows for proactive replacement before failures occur, minimizing downtime.
Remote Management:
- Implement a secure remote management solution (e.g., IPMI) to allow for remote monitoring and control of the server. This is crucial for troubleshooting issues outside of normal business hours. See Internal Document: IPMI Configuration and Security.
