Supermicro H11SSL-i and AMD EPYC 7351P with Linux installed – system (GCC flags),kernel and device information

Here is what you can expect if you have new Linux kernel 5.0.1 installed on H11SSL-i with AMD EPYC 7351P. Here you can see what is inside the BIOS – Supermicro H11SSL-i BIOS screenshot review – AMD EPYC 7351P 16-Core Processor

  • 3x SATA Controllers – SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)
  • 2x Ethernet Controllers – Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03)
  • 8x RAM DDIM in eight-channel mode

lspci – devices

Note there are 3 SATA controllers (SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)) for a total of 16 SATA physical onboard ports (8 of them are ordinary SATA physical ports on the board and for the other 8 you will need a cable – Supermicro MiniSAS HD to 4 SATA)!
