Power Requirements:

  • The server draws substantial power (up to 1300W under full load).
  • Dedicated power circuits are required.
  • Redundant power supplies provide failover protection.
  • Uninterruptible Power Supplies (UPS) are highly recommended to protect against power outages – see UPS Systems.

Hardware Monitoring:

  • Implement comprehensive hardware monitoring using IPMI, SNMP, or dedicated monitoring software.
  • Monitor CPU temperatures, fan speeds, power supply status, and disk health.
  • Configure alerts for critical events.

Storage Maintenance:

  • Regularly check RAID array health.
  • Monitor disk SMART attributes for potential failures.
  • Implement a data backup and recovery plan – see Data Backup Strategies.

Networking Maintenance:

  • Monitor network interface status and performance.
  • Update network drivers and firmware.
  • Implement network security measures.

Physical Security:

  • Secure the server room with restricted access.
  • Implement environmental controls (temperature, humidity).
  • Protect against physical damage.
