These benchmarks were conducted in a controlled environment. Actual performance may vary depending on workload, configuration, and environmental factors. See Performance Testing Methodology for a detailed description of the testing procedures.

Real-World Performance

In a real-world object storage deployment using Ceph, the configuration consistently achieves:

  • **Sustained throughput:** 20-25 GB/s for read operations and 15-20 GB/s for write operations.
  • **Low latency:** Average object access latency of less than 2ms for frequently accessed data on the NVMe tier.
  • **High scalability:** The cluster can scale horizontally by adding more nodes, increasing both capacity and performance.
  • **High availability:** Data redundancy and fault tolerance features ensure minimal downtime. See High Availability Architecture for details.

3. Recommended Use Cases

The Cloud Storage Solutions configuration is ideal for the following applications:

  • **Object Storage:** Serving as the foundation for a private or hybrid cloud object storage solution (e.g., using Ceph, MinIO, or OpenStack Swift).
  • **Backup and Disaster Recovery:** Providing a highly scalable and reliable target for backups and disaster recovery data.
  • **Archival Storage:** Storing large volumes of infrequently accessed data for long-term retention.
  • **Media Storage and Streaming:** Hosting large media libraries for video streaming, content delivery networks (CDNs), and media asset management.

5. Maintenance Considerations

Maintaining the Cloud Storage Solutions configuration requires careful planning and proactive monitoring.

Cooling

  • Data Center Cooling: This configuration generates significant heat due to the high-density storage and powerful processors. A data center with adequate cooling capacity (at least 5kW per rack) is essential.
  • Airflow Management: Proper airflow management within the rack is crucial to prevent overheating. Utilize blanking panels to fill empty slots and ensure unobstructed airflow. See Data Center Cooling Best Practices.
  • Fan Monitoring: Regularly monitor system fan speeds and temperatures to identify potential cooling issues.

Power Requirements

  • Power Distribution Units (PDUs): Utilize redundant PDUs with sufficient capacity to handle the power demands of the servers.
  • Power Redundancy: The redundant PSUs provide power redundancy, but a reliable power source and UPS (Uninterruptible Power Supply) are still recommended.
  • Power Consumption: Typical power consumption under full load is 1200-1500W per node.

Storage Media Management

  • Drive Monitoring: Implement a system for monitoring the health and status of all storage drives. Utilize SMART (Self-Monitoring, Analysis, and Reporting Technology) data to identify potential failures. See Drive Failure Prediction.
  • RAID Rebuilds: Be prepared for RAID rebuilds, which can impact performance. Schedule rebuilds during off-peak hours.
  • Data Scrubbing: Regularly perform data scrubbing to detect and correct data errors.
  • Firmware Updates: Keep storage drive firmware up to date to address bugs and improve performance.

Software Updates

  • Operating System Updates: Regularly apply operating system security patches and updates.
  • Storage Software Updates: Keep the storage software (e.g., Ceph, MinIO) up to date to benefit from bug fixes, performance improvements, and new features.

Remote Management

  • IPMI Access: Secure IPMI access for remote monitoring and management.
  • Network Segmentation: Segment the IPMI network from the production network for security reasons.
