  • Consider using an Uninterruptible Power Supply (UPS) to protect against power outages. Review UPS Selection and Configuration.
  • Monitor power consumption using IPMI or dedicated power monitoring tools.

Storage Maintenance

  • Regularly monitor the health of the hard drives and SSDs using RAID controller management software.
  • Perform RAID scrubbing to detect and correct data errors.
  • Implement a data backup and recovery plan. See Data Backup and Disaster Recovery.
  • Consider replacing hard drives proactively based on SMART data.

Software Updates

  • Keep the operating system and all software packages up to date with the latest security patches and bug fixes.
  • Regularly update the RAID controller firmware.
  • Monitor for security vulnerabilities and apply appropriate mitigations. Refer to Server Security Best Practices.

Remote Management

  • Securely configure the IPMI interface and restrict access to authorized personnel only.
  • Regularly review IPMI logs for any suspicious activity.
  • Use remote management tools to monitor server health and perform basic troubleshooting tasks. See Remote Server Administration.

Preventative Maintenance Schedule

A recommended preventative maintenance schedule includes:

  • **Monthly:** Visual inspection of components, dust removal, check fan status, review system logs.
