Új szelek a szerver technológiában

  1. 1. ÚJ SZELEK A SZERVER TECHNOLÓGIÁBAN Polányi Csaba Axico Informatikai Kft
  2. 2. NVME TECHNOLÓGIA
  3. 3. AZ NVME TELJESÍTMÉNYE Measurement NVMe SSD SATA3/SAS3 SSD NVMe Improvement Bandwidth vs. SATA3 128K Sequential Read 2788.77 MB/s 470.60 MB/s 5.93x 128K Sequential Write 1838.98 MB/s 453.33 MB/s 4.06x Bandwidth vs. SAS3 128K Sequential Read 2788.77 MB/s 980.34 MB/s 2.84x 128K Sequential Write 1838.98 MB/s 421.25 MB/s 4.37x Latency vs. SATA3 4K Sequential Read 15.9 µs 47.3 µs 2.97x 4K Sequential Write 17.6 µs 51.4 µs 2.92x Latency vs. SAS3 4K Sequential Read 15.9 µs 114.1 µs 7.18x 4K Sequential Write 17.6 µs 109.853 µs 6.24x
  4. 4. NVME ELŐNYÖK 4  Large throughput gains (6x)  Substantial latency improvements (7x)  Drive directly attached to CPU, eliminate HBA costs and overhead  Shared common backplane improves flexibility of drive choice  Improved power efficiency  Ultra-fast performance for demanding workloads  Multiple choices on form factors:  2.5" U.2 form factor for improved serviceability vs. PCI-E Flash cards (hot-swap)  EDSFF and NF1 form factors for dense 1U Petascale capacity
  5. 5. NVME FORM FACTOR U.2 (7.5mm/15.0mm) M.2 (without carrier) NF1 (without carrier) EDSFF Long (includes carrier) 69.85mm 100.45mm 110.0mm 110.0mm 30.5mm 318.75mm 111.49mm x4only x4onlyx4only 22.0mm 38.4mm 31.5mm NF1E1.S E1.L EDSFF Short (without carrier)
  6. 6. NVME SYSTEM APPLICATIONS 6  I/O Intensive Enterprise Applications  Advanced data mining  Online transaction processing (OLTP)  Financial transactions  High Density Hot Storage  HPC/Data Analytics  Media/Video Streaming  Content Delivery Network (CDN)  Big Data  Boot/OS drive
  7. 7. SUCCESS STORY (DATA ANALYTICS) – CEPH  Industry: Data Analytics  Application: Ceph  Territory: USA  First Installation: 8PB  NF1 Advantages:  Best All-Flash density  High performance CPU – 205W  Large memory capacity  High I/O bandwidth 30”
  8. 8. x16 x16 Node 2 CPU1 CPU2 Node 1 CPU1 CPU2 NVMe0 … NVMe23 Front Bay PCIE SWITCH PCIE SWITCH Dual Port NVMe Feature 2x PCI-E Lanes from each Switch (4x Lanes per device) x2 x2 x2 x2
  9. 9. 9 NVMe cost equal to SSD Performance much better Lower power consumption Multiple choices on form factors Driver/firmware ready and mature Applications need NVMe for better performance More importantly  Supermicro has the best NVMe solutions Mindenkit az NVMe-re!!!
  10. 10. 11 AMD EPYC CPU Roadmap  “Zen”  14nm “Milan”  “Zen 3”  7nm  IPC improvements  Consistent platform “Rome”  “Zen 2”  7nm+  IPC improvements  Higher memory speeds  PCIe4  Infinity Fabric Gen 2 2017 2020 “Naples” Performance LeadershipContinuous Innovation 2019
