  • **Fan Monitoring:** Continuously monitor fan speeds and temperatures using the BMC. Replace failing fans promptly. See Server Cooling System Maintenance.
  • **Data Center Temperature:** Maintain a data center temperature between 20-24°C (68-75°F).

Power Requirements

  • **Total Power Consumption:** Estimated maximum power consumption is 1800W.
  • **Dedicated Circuit:** The server requires a dedicated power circuit capable of delivering at least 20 amps at 208V or 15 amps at 120V.
  • **Redundancy:** Utilize redundant power supplies to ensure uptime in the event of a power supply failure.

Storage Maintenance

  • **RAID Monitoring:** Regularly monitor the RAID array status for errors or drive failures.
  • **SMART Monitoring:** Enable SMART (Self-Monitoring, Analysis and Reporting Technology) on all drives to proactively identify potential failures.
  • **Firmware Updates:** Keep the RAID controller and drive firmware up to date.
  • **Drive Replacement:** Follow proper procedures for hot-swapping failed drives. See Storage Array Management.

Software Updates

  • **Operating System:** Regularly apply security patches and updates to the operating system.
  • **Firmware:** Update server firmware (BIOS, BMC, NICs) to ensure optimal performance and security.
  • **Drivers:** Keep device drivers up to date.

Regular Checks

  • **Log Review:** Regularly review system logs for errors or warnings.
  • **Physical Inspection:** Periodically inspect the server for dust buildup and loose connections.
