Testy budżetowego serwera 1U AMD dla 4 dysków NVMe gen 4.0 (Czy BPN-SAS3-815TQ-N4 obsłuży dyski NVMe gen 4.0?)

Zbudowaliśmy dla Klienta serwer 1U ITC-RR3R wyposażony w procesor AMD Epyc Rome 7542 32C/64T 2.9G 128MB i sprawdziliśmy czy backplane BPN-SAS3-815TQ-N4, w który wyposażona jest obudowa CSE-813MF2TQC4-R407CB obsłuży dyski NVMe Gen 4.0.

Supermicro 1U server NVMe ITC

Konfiguracja:

  1. Obudowa Supermicro CSE-813MF2TQC4-R407CB 1U, Hot-Swap 4xHDD SAS3/SATA3/NVMe, 400W Redundant
  2. Płyta główna Supermicro MBD-H12SSL-NT ATX, obsługująca jeden procesor AMD Epyc 7003/7002, do 2TB pamięci RAM w 8 modułach. Posiadająca dwa sloty M.2 (22x80, 22x110) oraz 2 porty SlimSAS x8, obsługujace 2 dyski NVMe każdy. Obsługa sieci zapewniana jest przez kartę sieciową Broadcom BCM57416 2x10GBase-T. Za zarzadzanie odpowiedzialny jest moduł ASPEED AST2500
  3. Procesor PSE-ROM7542-0075 AMD Epyc Rome 7542 32C/64T 2.9G 128MB
  4. Radiator Supermicro SNK-P0062P 1U pasywny, dedykowany socketowi SP3
  5. Pamieć RAM 512GB DDR4 ECC Registered (8 x 64GB MEM-DR464L-SL03-ER32)
  6. Dysk HDS-SUN0-MZQL2960HCJRA7 Samsung PM9A3 960GB NVMe PCIe4x4 U.2 7mm 1DWPD 5YR SED Opal
  7. Dysk HDS-TUN0-KCD6XLUL960G Kioxia CD6-R 960GB NVMe PCIe4x4 2.5" 15mm SIE 1DWPD 5YR
  8. Dysk M.2 HDS-MMN-MTFDKBA480TFR1BC - Micron 7450 PRO 480GB NVMe PCIe 4.0 M.2 22x80mm 3D TLC
  9. Dedykowany Riser Card RSC-S-6G4 1U Left Standard wyposażony w slot PCI-E 4.0 x16
  10. Kable CBL-SAST-0817 do połączenia płyty głównej z backplane do obsługi dysków NVMe
  11. Licencja SFT-OOB-LIC, rozszerzająca możliwości IPMI.

Pierwsze uruchomienie

  1. Podłączyliśmy serwer do prądu oraz sieci. Zalogowaliśmy się do IPMI. IPMI wykryło dysk.
  2. Uruchomiliśmy system operacyjny Kubuntu 23.10 live USB, jednak lspci nie pokazało żadnych urządzeń, które moglibyśmy uznać za nasze dyski NVMe.
  3. Uruchomiliśmy ponownie serwer i w BIOS zmieniliśmu opcję NVMe Firmware Source z Vendor na AMI Native Support
    • BIOS → Advanced → PCIe/PCI/PNP Configuration → NVMe Firmware Source Select [AMI Native Support].
  4. Uruchomiliśmy ponownie i wydaliśmy polecenie nvme oraz lspci: 
    • # nvme list -v
