Tests of a Budget 1U AMD Epyc Server for 4 NVMe Gen 4.0 Drives (Will the BPN-SAS3-815TQ-N4 Support NVMe Gen 4.0 Drives?)

We built a 1U ITC-RR3R server for a client, equipped with an AMD Epyc Rome 7542 32C/64T 2.9G 128MB processor, and tested whether the BPN-SAS3-815TQ-N4 backplane, which is included in the CSE-813MF2TQC4-R407CB chassis, supports NVMe Gen 4.0 drives.

Supermicro 1U server NVMe ITC

Sure, here's the translation:

Configuration:

Chassis: Supermicro CSE-813MF2TQC4-R407CB 1U, Hot-Swap 4xHDD SAS3/SATA3/NVMe, 400W Redundant
Motherboard: Supermicro MBD-H12SSL-NT ATX, supporting a single AMD Epyc 7003/7002 processor, up to 2TB RAM in 8 modules. It has two M.2 slots (22x80, 22x110) and 2 SlimSAS x8 ports, each supporting 2 NVMe drives. Network support is provided by a Broadcom BCM57416 2x10GBase-T network card. Management is handled by an ASPEED AST2500 module.
Processor: PSE-ROM7542-0075 AMD Epyc Rome 7542 32C/64T 2.9G 128MB
Heatsink: Supermicro SNK-P0062P 1U passive, dedicated to SP3 socket
RAM: 512GB DDR4 ECC Registered (8 x 64GB MEM-DR464L-SL03-ER32)
Drive: HDS-SUN0-MZQL2960HCJRA7 Samsung PM9A3 960GB NVMe PCIe4x4 U.2 7mm 1DWPD 5YR SED Opal
Drive: HDS-TUN0-KCD6XLUL960G Kioxia CD6-R 960GB NVMe PCIe4x4 2.5" 15mm SIE 1DWPD 5YR
Drive: HDS-MMN-MTFDKBA480TFR1BC - Micron 7450 PRO 480GB NVMe PCIe 4.0 M.2 22x80mm 3D TLC
Dedicated Riser Card: RSC-S-6G4 1U Left Standard equipped with PCI-E 4.0 x16 slot
Cables: CBL-SAST-0817 to connect the motherboard to the backplane for NVMe drive support
License: SFT-OOB-LIC, extending IPMI capabilities

First Boot

We connected the server to power and the network. We logged into IPMI. IPMI detected the disk. We booted the operating system from a Kubuntu 23.10 live USB, but lspci did not show any devices that could be identified as our NVMe drives. We restarted the server and changed the NVMe Firmware Source option in the BIOS from Vendor to AMI Native Support.

BIOS → Advanced → PCIe/PCI/PNP Configuration → NVMe Firmware Source Select [AMI Native Support].

Restart and Commands Execution

We restarted the server and issued the nvme and lspci commands:

# nvme list -v

Installation for Testing

To conduct the tests, we installed Kubuntu on the M.2 NVMe drive.

Tests

We used the fio command to conduct tests, starting with sequential read, followed by random read.
