  • **Log Management:** Implement a robust log management system to collect and analyze system logs for troubleshooting and security auditing. See System Log Analysis.
  • **Regular Physical Inspection:** Conduct periodic physical inspections of the server to check for dust buildup, loose cables, and other potential issues.
  • **RAID Maintenance:** Regularly check RAID array status and perform consistency checks to ensure data integrity. Maintain spare drives for hot-swap replacement. See RAID Array Management.
  • **Network Configuration Backups:** Back up network configurations regularly to facilitate rapid recovery in case of network failures. See Network Configuration Management.
  • **IPMI Access Control:** Secure IPMI access with strong passwords and restrict access to authorized personnel only. See IPMI Security Hardening.
