Regular monitoring of temperatures is crucial to prevent overheating. See Data Center Cooling for best practices.

Power Requirements: The dual 1600W power supplies provide ample power, but a dedicated power circuit is required. Uninterruptible Power Supply (UPS) protection is essential to ensure continuous operation during power outages. See Power Management for details.

Software Updates: Regularly update the operating system, security software, and firmware to patch vulnerabilities and maintain optimal performance. A robust patching strategy is critical for protecting against zero-day exploits. See Security Patch Management.

Storage Management: Implement a comprehensive storage management plan, including regular backups, data archiving, and disk space monitoring. RAID array health should be monitored continuously. See Storage Area Networks.

HSM Maintenance: Follow the manufacturer's recommendations for HSM maintenance, including key rotation and firmware updates. Secure access to the HSM is paramount.

Network Monitoring: Continuously monitor network traffic and performance to detect anomalies and potential security threats. A network intrusion detection system (NIDS) can provide real-time alerts. See Network Monitoring Tools.

Physical Security: The server should be housed in a secure data center with restricted access. Physical security measures, such as surveillance cameras and access control systems, are essential. See Data Center Security.

Regular Audits: Conduct regular security audits to identify vulnerabilities and ensure compliance with relevant regulations.
