Overview

This document details the hardware configuration optimized for providing robust and scalable Cloud Backup Services. This configuration is designed to handle large volumes of data ingestion, deduplication, compression, encryption, and long-term storage with high availability and data integrity. It focuses on balancing cost-effectiveness with performance, prioritizing storage capacity and I/O operations per second (IOPS) while maintaining acceptable compute power. The architecture utilizes a distributed system approach, leveraging commodity hardware for scalability and redundancy. This document covers hardware specifications, performance characteristics, recommended use cases, comparisons with alternatives, and essential maintenance considerations. See also Data Center Infrastructure for overall facility requirements.

1. Hardware Specifications

The Cloud Backup Services configuration is built around a scale-out architecture comprised of three primary node types: Ingestion/Processing Nodes, Storage Nodes, and Metadata/Control Nodes. Each node type has specific hardware requirements detailed below. All nodes utilize a standardized server chassis – the Supermicro 8U 4-Node server chassis (CSS-846E) for density and efficient power/cooling. This allows for flexible scaling within existing rack infrastructure. See Server Chassis Selection for details on chassis choice rationale.

Motherboard Supermicro X11DPG-QT - Dual Socket Intel Xeon Scalable Processor Motherboard.

2. Performance Characteristics

The performance of this configuration is evaluated based on several key metrics: data ingestion rate, deduplication efficiency, compression ratio, and recovery time. All benchmarks were performed in a controlled environment with simulated client load. See Performance Testing Methodology for detailed test procedures.

  • **Data Ingestion Rate:** Average 500 MB/s per Ingestion/Processing Node, scaling linearly with the number of nodes. Maximum observed ingestion rate: 2.5 GB/s with 5 nodes.
  • **Deduplication Efficiency:** Average 80-90% deduplication ratio, depending on the data type. The use of Deduplication Algorithms significantly impacts this value.
  • **Compression Ratio:** Average 2:1 compression ratio using LZ4 compression. See Data Compression Techniques for algorithm details.
  • **Recovery Time:** Average recovery time of 10-20 minutes for a 1TB dataset, depending on network bandwidth and storage node performance. Utilizing Data Recovery Strategies can optimize this.
  • **IOPS (Storage Nodes):** Sustained 150,000 IOPS read/write.
  • **Latency (Storage Nodes):** Average latency of 3-5ms.

These results demonstrate the configuration's ability to handle large-scale backup operations efficiently. Performance monitoring tools like Prometheus and Grafana are integrated for real-time performance analysis. See Server Monitoring and Alerting.

3. Recommended Use Cases

This configuration is ideally suited for the following scenarios:

  • **Large Enterprises:** Organizations with terabytes or petabytes of data to back up.
  • **Managed Service Providers (MSPs):** Offering Cloud Backup as a Service (BaaS) to their clients.
  • **Disaster Recovery (DR):** Providing offsite backups for business continuity.
  • **Long-Term Archiving:** Storing data for compliance and regulatory purposes.
  • **Virtual Machine Backups:** Protecting virtualized environments. See Virtual Machine Backup Best Practices.
  • **Database Backups:** Reliable backups of critical database systems. See Database Backup and Recovery.

This configuration is *not* recommended for small businesses with limited data volumes or for applications requiring extremely low latency access to backup data. For those scenarios, a simpler, single-server solution might be more appropriate.

4. Comparison with Similar Configurations

Here's a comparison of this Cloud Backup Services configuration with two alternative options:
