AMD EPYC™ 9004 Series Processors Enable Transformative Flash Storage Performance

  • mail

The PCIe® interface is a critical backbone for moving data at high bandwidth between the host processor and connected peripherals in modern enterprise and cloud data centers. The incumbent PCIe generation, PCIe 4.0, delivers 16 GT/s data transfer speed, achieving full d

*Disclaimer-Performance may vary on system conditions.

Flexible I/O Tester (FIO) is a widely used storage performance benchmarking tool. A series of FIO tests were performed using this tool to characterize the performance of the 4th Generation AMD EPYC processor under various storage workloads with all 24 slots of SSDs populated with 1.92TB PM1743. These tests show that the performance scales linearly as more drives are plugged in for testing, from one to 24 drives.

For a fully populated server, we achieved > 220GB/s of sequential read, >63,000 MB/s for sequential write, >37 MIOPs of random read and > 14,000 kIOPs of random write performance. The graphs below show the raw throughput data of the FIO tests on the AMD “Titanite” reference platform with Samsung PM1743 SSD.

Conclusion

The results achieved in this study are truly exceptional and demonstrate how AMD and Samsung can address specific performance challenges and provide solutions for applications with virtually insatiable demands for data.
