  1. Contact Form Server Configuration - Technical Documentation

This document details the hardware configuration known internally as "Contact Form," designed for hosting lightweight web applications, specifically contact forms and small static websites. It prioritizes cost-effectiveness and energy efficiency while maintaining acceptable performance for its intended use cases. This configuration is *not* intended for demanding workloads like databases or large-scale web applications. See Server Configuration Guidelines for overall design philosophy.

1. Hardware Specifications

The "Contact Form" server configuration utilizes a minimalist approach. Every component has been selected for optimal price-performance ratio for the target workload. A detailed breakdown follows:

Component Specification Manufacturer (Example) Part Number (Example) Notes
CPU Intel Celeron G6900 (2 Cores, 2 Threads, 3.4 GHz Base Clock, 3.7 GHz Turbo Boost) Intel CM8067204249868 Low power consumption, sufficient for basic web serving. See CPU Selection Criteria for justification.
Motherboard ASRock H610M-ITX/ac ASRock H610M-ITX/ac Mini-ITX form factor for space efficiency. Supports one DDR4 DIMM. See Motherboard Compatibility for supported components.
RAM 8GB DDR4 3200MHz SODIMM Crucial CT8G4SFRA32A Single channel configuration. Higher speeds are beneficial for even light workloads. See Memory Configuration.
Storage 240GB SATA III 2.5" SSD Samsung MZ-7LM240B/AM Reliable solid-state storage for fast boot times and application loading. See Storage Solutions.
Network Interface Card (NIC) Integrated Intel Gigabit Ethernet Intel (on Motherboard) N/A Sufficient for typical contact form traffic. See Network Infrastructure.
Power Supply Unit (PSU) 300W 80+ Bronze Certified Corsair CP-300W-GM Energy efficient and provides adequate power for the components. See Power Supply Requirements.
Case Mini-ITX Tower Case (e.g., Silverstone SG13) Silverstone SST-SG13B-H Compact form factor to minimize space requirements. See Server Chassis Options.
Operating System Ubuntu Server 22.04 LTS Canonical N/A Lightweight and secure Linux distribution. See Operating System Standards.

This configuration deliberately avoids redundancy features like RAID or redundant power supplies to minimize cost. Data backups are the primary method of data protection, as outlined in the Data Backup and Recovery Plan.

2. Performance Characteristics

The "Contact Form" server prioritizes efficiency over raw performance. The following benchmark results provide an overview of its capabilities:

  • **CPU Performance (Geekbench 5):** Single-Core: 1200, Multi-Core: 2400 (approximate). This is sufficient for handling concurrent contact form submissions without significant delays.
  • **Disk I/O (CrystalDiskMark):** Sequential Read: 500 MB/s, Sequential Write: 450 MB/s. The SSD ensures fast loading of web pages and quick processing of form data.
  • **Network Throughput (iperf3):** 940 Mbps (typical). The Gigabit Ethernet connection provides ample bandwidth for expected traffic levels.
  • **Web Server Response Time (Apache Benchmark - ab):** Average response time of 0.2 seconds for 100 concurrent users submitting a simple HTML form. This is acceptable for most contact form applications. See Performance Testing Procedures for details on testing methodology.
  • **Power Consumption:** Idle: 15W, Load (100% CPU): 65W. This low power consumption translates to lower operating costs and reduced environmental impact. See Power Management Policies.
    • Real-world Performance:**

In a production environment simulating 50 concurrent users submitting contact forms per hour, the server maintained an average response time of under 0.3 seconds. CPU utilization rarely exceeded 20%, and memory usage remained below 4GB. This demonstrates the configuration's ability to handle typical workload demands comfortably. However, scaling beyond this level may require upgrading to a more powerful configuration, such as the "Small Business Web Server" (see Comparison with Similar Configurations). Monitoring tools like Server Monitoring System are crucial for tracking performance metrics and identifying potential bottlenecks.

3. Recommended Use Cases

This configuration is ideally suited for the following applications:

  • **Hosting static websites:** Simple HTML, CSS, and JavaScript websites.
  • **Contact forms:** Processing submissions from contact forms (e.g., using PHP, Python, or Node.js).
  • **Small personal blogs:** Blogs with low traffic and minimal dynamic content.
  • **Development/Testing environments:** A cost-effective platform for testing web applications.
  • **Internal tools:** Hosting small internal web applications for team use.
  • **Simple API endpoints:** Serving lightweight APIs.

This configuration is *not* recommended for:

  • **High-traffic websites:** Websites with a large number of concurrent users.
  • **Database-driven applications:** Applications that require a dedicated database server.
  • **Resource-intensive applications:** Applications that demand significant CPU or memory resources.
  • **E-commerce websites:** Websites that process online transactions. See Security Best Practices for considerations when handling sensitive data.



4. Comparison with Similar Configurations

The "Contact Form" configuration occupies a specific niche in our server lineup. Here's a comparison with similar options:

Configuration CPU RAM Storage Price (Approximate) Recommended Use Cases
**Contact Form** Intel Celeron G6900 8GB DDR4 240GB SSD $300 Contact forms, static websites, small personal blogs.
**Small Business Web Server** Intel Core i3-12100 16GB DDR4 480GB SSD $600 Small business websites, WordPress sites, basic e-commerce.
**Entry-Level Database Server** Intel Xeon E-2324G 32GB DDR4 ECC 960GB SSD $1200 Small databases, web applications with moderate database access.
**Developer Workstation** AMD Ryzen 5 5600X 32GB DDR4 1TB NVMe SSD $800 Software development, testing, virtual machines.
    • Key Differences:**
  • **CPU:** The "Contact Form" utilizes a Celeron processor, which is less powerful than the Core i3 or Xeon processors found in other configurations. However, it's sufficient for the intended workload.
  • **RAM:** 8GB of RAM is adequate for basic web serving, but more demanding applications require 16GB or 32GB.
  • **Storage:** The 240GB SSD provides sufficient storage for a small website and contact form data. Larger websites or applications require more storage capacity. See Storage Capacity Planning for guidance.
  • **Price:** The "Contact Form" is the most affordable option, making it ideal for budget-conscious users.


5. Maintenance Considerations

Maintaining the "Contact Form" server requires minimal effort due to its simplified hardware configuration. However, the following considerations are important:

  • **Cooling:** The Celeron processor generates relatively little heat. The stock CPU cooler is typically sufficient, but ensure adequate airflow within the case. Regularly check for dust accumulation, as outlined in the Server Room Cleaning Procedures.
  • **Power Requirements:** The 300W PSU provides ample power for the components. Ensure the server is connected to a reliable power source with surge protection. Monitor power consumption using Power Monitoring Tools.
  • **Software Updates:** Regularly update the operating system and web server software to patch security vulnerabilities and improve performance. Automated update tools can simplify this process. See Security Patching Schedule.
  • **Data Backups:** Implement a regular data backup schedule to protect against data loss. Backups should be stored offsite. Refer to the Data Backup and Recovery Plan.
  • **Monitoring:** Use server monitoring tools to track CPU usage, memory usage, disk space, and network traffic. Set up alerts to notify administrators of potential issues. See Server Monitoring System.
  • **Physical Security:** The server should be housed in a secure location with restricted access. See Data Center Security Protocols.
  • **SSD Lifespan:** SSDs have a limited number of write cycles. Monitor the SSD's health and consider replacing it proactively after several years of heavy use. Utilize SSD Monitoring Tools.
  • **Log Management:** Implement a log management system to collect and analyze server logs. This can help identify security threats and troubleshoot performance issues. See Log Analysis Procedures.
  • **Power Redundancy:** While this configuration does not include a redundant power supply, consider a UPS (Uninterruptible Power Supply) for short-term power outage protection. See UPS Selection and Configuration.
