  • **Firmware Updates:** Regularly update the server firmware (BIOS, RAID controller, NIC) to address security vulnerabilities and improve performance. Follow the manufacturer’s recommendations for update procedures. See Server Firmware Management.
  • **Storage Drive Monitoring:** Monitor the health of all storage drives using SMART (Self-Monitoring, Analysis and Reporting Technology) data. Replace failing drives proactively to prevent data loss. Implement automated alerts for drive failures. Refer to Storage Drive Health Monitoring.
  • **RAID Maintenance:** Periodically check the RAID array for errors and rebuild any degraded arrays promptly. Ensure that hot spare drives are available to automatically replace failed drives.
  • **Network Monitoring:** Monitor network performance and identify potential bottlenecks. Utilize network monitoring tools to track bandwidth usage, latency, and packet loss.
  • **Security Audits:** Regularly conduct security audits to identify and address vulnerabilities. Implement intrusion detection and prevention systems. See Server Security Hardening.
  • **Physical Security:** Ensure the server is housed in a secure data center with restricted access and physical security measures.
  • **Backup and Recovery Testing:** Regularly test the backup and recovery procedures to ensure data can be restored in a timely manner.
  • **Dust Control:** Implement a dust control plan to prevent dust buildup inside the server chassis, which can lead to overheating and component failure.
