* '''Cooling System:'''  High-performance servers require robust cooling solutions.  These servers utilize a closed-loop liquid cooling system to dissipate heat effectively. [[Liquid Cooling Systems]]
* '''Data Center Environment:'''  Data centers must maintain a consistent temperature and humidity level (typically 20-24°C and 40-60% relative humidity).
* '''Airflow Management:'''  Proper airflow management within the server rack is crucial to prevent hotspots.  Blanking panels are used to fill unused rack spaces.

=== 5.2 Power Requirements ===

* '''Total Power Consumption:'''  A fully loaded server can draw up to 3200W.
* '''Power Distribution Units (PDUs):'''  Redundant PDUs with sufficient capacity are essential.
* '''UPS (Uninterruptible Power Supply):'''  A UPS system is required to provide backup power in case of power outages.
* '''Power Cabling:'''  High-quality, appropriately sized power cables are necessary.

=== 5.3 Software Updates & Patching ===

* '''Operating System:'''  Regularly apply security patches and updates to the operating system (currently Ubuntu Server 22.04 LTS). [[Operating System Security]]
* '''Firmware Updates:'''  Keep server firmware (BIOS, BMC, RAID controller) up to date.
* '''CI/CD Software:'''  Update CI/CD tools (Jenkins, GitLab CI, CircleCI, etc.) to the latest versions. [[CI/CD Tooling]]

=== 5.4 Hardware Maintenance ===

* '''Preventative Maintenance:'''  Regularly inspect hardware components for signs of wear and tear.
* '''Component Replacement:'''  Have spare components on hand for quick replacement in case of failures (PSUs, RAM, SSDs).
* '''Log Analysis:'''  Monitor system logs for error messages and potential issues. [[System Log Analysis]]
* '''Remote Monitoring:''' Utilize IPMI and other remote management tools for proactive monitoring and troubleshooting.

=== 5.5 Security Considerations ===

* '''Physical Security:'''  Data centers must have robust physical security measures in place (access control, surveillance).
* '''Network Security:'''  Firewalls, intrusion detection systems, and other network security tools are essential. [[Network Security Best Practices]]
* '''Data Encryption:'''  Encrypt sensitive data both in transit and at rest. [[Data Encryption Methods]]
* '''Vulnerability Scanning:'''  Regularly scan for vulnerabilities in the CI/CD infrastructure.
