Random read/write IOPS (Input/Output Operations Per Second) are in excess of 800,000, providing extremely responsive storage access. RAID 1 and RAID 6 configurations provide redundancy and performance optimization. Storage Performance Metrics.
- **Network Performance:** The 25 Gigabit Ethernet NICs deliver a theoretical maximum throughput of 25 Gbps. Real-world testing with iperf3 consistently achieves sustained throughput of 20 Gbps, limited primarily by network infrastructure. RoCEv2 significantly reduces latency for applications requiring low-latency network communication. Network Performance Testing.
- **Virtualization Performance:** Using KVM (Kernel-based Virtual Machine) hypervisor, the server can comfortably run up to 20 virtual machines simultaneously, each with 4 vCPUs and 16 GB of RAM, without significant performance degradation. Virtualization Technologies.
- **Real-World Scenario – Client Image Analysis:** Analyzing a 50 GB client system image takes approximately 5 minutes, compared to 15 minutes on a comparable server with SATA SSDs. This is a crucial metric for rapid issue diagnosis.
- **Real-World Scenario – Log File Analysis:** Aggregating and analyzing 1 TB of client log files takes approximately 30 minutes, using tools like `grep`, `awk`, and custom scripts.
These performance characteristics demonstrate the server’s suitability for demanding client troubleshooting tasks.
