5. Maintenance Considerations
Maintaining the Change Management server configuration requires proactive monitoring and regular maintenance to ensure optimal performance and reliability.
Cooling:
- The server generates significant heat due to the high-performance CPUs and storage devices. Adequate cooling is essential. Rack-mounted servers should be installed in a climate-controlled data center with sufficient airflow. Liquid cooling solutions may be considered for extremely high-density deployments. See Data Center Cooling Methods.
- Regularly check and clean air filters to maintain optimal airflow.
- Monitor CPU and component temperatures using IPMI or dedicated monitoring software.
Power Requirements:
- The server requires a dedicated power circuit with sufficient capacity to handle the peak power draw of approximately 1800W (including both PSUs at full load).
- Ensure that the power circuit is properly grounded.
- Use a UPS (Uninterruptible Power Supply) to protect against power outages. See UPS Systems for further details.
Storage Maintenance:
- Regularly monitor the health of the storage devices using SMART data.
- Implement a robust backup and disaster recovery plan. Test backups regularly to ensure they are restorable.
- Consider using storage tiering to optimize performance and cost.
- Defragment SAS HDDs periodically to maintain performance. (Not necessary for SSDs).
Network Maintenance:
- Monitor network bandwidth utilization and latency.
- Regularly update the firmware on the NICs.
- Review network security logs for suspicious activity.
Software Maintenance:
- Keep the operating system, drivers, and applications up to date with the latest security patches.
- Regularly review system logs for errors and warnings.
- Perform performance monitoring and tuning to optimize system performance. See System Performance Monitoring.
Hardware Lifecycle:
- Plan for hardware replacements every 3-5 years to maintain optimal performance and take advantage of new technologies. See Server Lifecycle Management.
Remote Management:
- Utilize the IPMI interface for remote monitoring, control, and troubleshooting.
Security Considerations:
- Implement strong access control policies.
- Regularly review security logs.
- Ensure that the server is protected by a firewall.
- Encrypt sensitive data at rest and in transit. See Server Security Best Practices.
