Will a 6-Node NVMe Ceph Cluster Outperform a 5-Node NVMe Ceph Cluster? Build, Bench & Expand Part 4

Описание: In this fourth and final episode of our Build, Bench and Expand series, we put our recently expanded 6-node NVMe Ceph cluster to the ultimate performance test. Discover the incredible scalability improvements achieved by adding just one additional node (including tweaks) to our high-performance storage cluster.

What You'll Learn in This Video:
✅ Complete performance comparison between 5-node vs 6-node Ceph clusters
✅ Single-threaded and multi-threaded benchmark analysis
✅ Sequential and random read/write performance metrics
✅ Real-world saturation testing with multiple clients
✅ Linear scaling analysis and performance gains

Key Performance Results:
Sequential Write: 16.5GB/s (47% improvement from 11.2GB/s)
Sequential Read: 50GB/s (52% improvement from 33GB/s)
Random Write IOPS: 515,000 (57% improvement from 328,000)
Random Read IOPS: 2.3 million (19% improvement from 1.8 million)

This comprehensive benchmark demonstrates how Ceph's distributed storage architecture scales beautifully with additional nodes, delivering substantial performance improvements across all workload types.

Whether you're planning enterprise storage deployments or building high-performance homelab clusters, these results showcase the real-world benefits of horizontal scaling.
