2. Performance Characteristics

Performance is measured using a combination of synthetic benchmarks and real-world workload simulations.

2.1. Synthetic Benchmarks

  • **CPU:** SPECint® 2017 rate3: Approximately 250 (per node - scaled with number of nodes)
  • **Memory:** STREAM Triad: 250 GB/s (per node) - Demonstrates high memory bandwidth.
  • **Storage (NVMe):** Sequential Read: 7 GB/s, Sequential Write: 6 GB/s (per node)
  • **Network:** iPerf3: 95 Gbps (between nodes) - Demonstrates near-line-rate network performance with RDMA.

2.2. Real-World Workload Simulations

  • **Hadoop/MapReduce:** TeraSort benchmark - Sorting 1 TB of data took 15 minutes with a 10-node cluster. Scales linearly with added nodes.
  • **Spark:** TPC-DS (Decision Support) benchmark - Running a complex analytical query against a 10 TB dataset completed in 45 minutes with a 10-node cluster.
  • **Presto:** Ad-hoc query performance on a 5 TB dataset - Average query response time of 3 seconds for complex queries involving multiple joins.
  • **Machine Learning (TensorFlow):** Training a deep learning model (ResNet-50) on ImageNet dataset – 24 hours with a 10-node cluster. GPU acceleration (see section 5.1) would significantly reduce this time.

These results demonstrate the platform's ability to handle large datasets and complex analytical workloads efficiently. Performance scales predictably with the addition of compute and storage nodes.

3. Recommended Use Cases

5.3. Software Updates and Patching

  • **Operating System:** Regularly apply security patches and updates to the operating system (e.g., CentOS, Ubuntu Server).
  • **Hadoop/Spark/Presto:** Keep the Big Data software stack up to date with the latest versions.
  • **Firmware Updates:** Update server firmware (BIOS, NIC, RAID controller) to the latest versions. See Server Firmware Management.

5.4. Storage Management

  • **RAID Monitoring:** Monitor RAID array health and proactively replace failing drives.
  • **Data Backup and Recovery:** Implement a comprehensive data backup and recovery plan.
  • **Data Archiving:** Archive infrequently accessed data to lower-cost storage tiers.
