  • Use dedicated power circuits for the server to avoid overloading.
  • Implement power monitoring to track energy consumption and identify potential issues.

Storage Maintenance:

  • Regularly monitor the health of the hard drives and SSDs using SMART monitoring tools.
  • Implement a robust backup and recovery strategy to protect against data loss. See Data Backup and Recovery Strategies.
  • Periodically check RAID array status to ensure data integrity.
  • Consider using storage tiering to optimize performance and cost.

Network Maintenance:

  • Monitor network performance and identify potential bottlenecks.
  • Keep the NIC firmware up to date.
  • Implement network segmentation to improve security and performance.

Software Updates:

  • Regularly apply operating system and firmware updates to address security vulnerabilities and improve performance.
  • Implement a patch management system to automate the update process.

Physical Security:

  • Ensure the server is located in a secure data center with restricted access.
  • Implement physical security measures such as locks and surveillance cameras.

Remote Management:

  • Utilize the IPMI interface for remote monitoring and management.
