2. Performance Characteristics

The performance of this configuration has been evaluated using several benchmarks relevant to containerized workloads.

  • **CPU Performance:** Using the SPEC CPU 2017 benchmark suite, the EPYC 7543P achieves a score of approximately 180 (base) and 250 (peak) for integer and floating-point workloads, respectively. This indicates strong performance for both CPU-intensive and computationally demanding container applications. See CPU Benchmarking for Servers for in-depth benchmark analysis.
  • **Memory Performance:** The DDR4-3200 memory provides a bandwidth of 25.6 GB/s. Memory latency is typically around 60-70ns. This is sufficient for handling the memory demands of a large number of containers. Tools like `stress-ng` can be used to evaluate memory performance under load. See Memory Performance Testing.
  • **Storage Performance:** The RAID 6 array of SAS HDDs provides a sustained read/write speed of approximately 400 MB/s. IOPS are around 10,000. While this is lower than NVMe SSDs, it is adequate for many containerized applications, particularly those that are I/O bound but not requiring extremely low latency. `fio` is a valuable tool for measuring storage performance. Refer to Storage Performance Measurement.
  • **Network Performance:** The 25GbE NICs provide a theoretical maximum throughput of 25 Gbps. Real-world throughput will be slightly lower due to overhead, typically around 20-22 Gbps. `iperf3` can be used to test network bandwidth. See Network Performance Testing.
  • **Container Density:** This configuration can comfortably support approximately 150-200 containers, depending on the resource requirements of each container. Testing with a representative workload is crucial to determine optimal container density. Consider using tools like `cAdvisor` for container resource monitoring. See Container Resource Monitoring.
    • Real-world performance:**

Running a typical microservices application (e.g., a web application with a database backend) within Docker containers on this hardware, we observed the following:

  • **Average CPU utilization:** 40-60% under moderate load.
  • **Average memory utilization:** 60-80% under moderate load.
  • **Average disk I/O utilization:** 20-30% under moderate load.
  • **Average network utilization:** 5-10% under moderate load.

These figures demonstrate that the configuration has sufficient headroom to handle spikes in traffic and accommodate future growth.


3. Recommended Use Cases

This server configuration is ideally suited for the following use cases:

  • **Web Application Hosting:** Hosting containerized web applications, including those built with frameworks like Node.js, Python (Django/Flask), and Ruby on Rails.
  • **Microservices Architectures:** Deploying and managing microservices applications using container orchestration platforms like Kubernetes. The high core count and memory capacity are well-suited for running a large number of microservices.
  • **CI/CD Pipelines:** Running continuous integration and continuous delivery (CI/CD) pipelines using tools like Jenkins, GitLab CI, or CircleCI.
  • **Batch Processing:** Executing batch processing jobs, such as data analytics or machine learning tasks, in containers.
  • **Development and Testing Environments:** Providing scalable and isolated development and testing environments for software developers.
  • **Database Hosting (Smaller Instances):** Hosting smaller database instances (e.g., PostgreSQL, MySQL) in containers – consider NVMe storage for higher performance database workloads. See Database Containerization Best Practices.
  • **Message Queues:** Running message queueing systems like RabbitMQ or Kafka within containers.

This configuration excels in scenarios where resource consolidation and efficient utilization are priorities.
