AsRock J5040 NAS setup with 32Gb RAM and LSI RAID card support
the goal is to build a low power NAS (<30W) with enough RAM (32Gb) LSI RAID card are too power hungry (>10W) and SAS drive are not better but I wanted to try to see if I could make it work.
1X J5040-ITX motherboard : https://www.asrock.com/mb/Intel/J5040-ITX/index.fr.asp 2X G.Skill Ripjaws 16GB, 2400 MHz, DDR4-RAM, SO-DIMM https://www.digitec.ch/en/s1/product/gskill-ripjaws-2-x-16gb-2400-mhz-ddr4-ram-so-dimm-ram-11230127 1X sata SSD 120 Gb
for the data storage, I have 2 variant :
1X PCIe LSI raid card : https://fr.aliexpress.com/item/1005004679780618.html 1X PCIe X1 X16 with power injector : https://fr.aliexpress.com/item/1005001382338955.html 2X SAS cable : https://fr.aliexpress.com/item/1005004403091207.html 6-8X SATA HDD
1X PCie SATA Expander : https://fr.aliexpress.com/item/4000433243029.html 6X SATA HDD
for the power supply I have 2 variant :
1X PSU jack to molex adapter : https://www.digitec.ch/en/s1/product/intertech-mini-itx-psu-nas-200-w-power-supply-pc-15658837 1X power brick 12 V Barrel Jack (50-100 W) 1X Molex to SATA expender : https://fr.aliexpress.com/item/1005002534885657.html
1X stadard ATX PSU
the official specs says that the J5040 only support up 8Gb or RAM. but it works with 32 Gb too you just need to have the right kind of ram stick. I could find a few thread online that reported that theses two model worked :

gskill ripjaws 2 x 16gb 2400 mhz ddr4 : https://www.digitec.ch/en/s1/product/gskill-ripjaws-2-x-16gb-2400-mhz-ddr4-ram-so-dimm-ram-11230127
when I plugged the ripjaws in the motherboard it didnt work. I had to remove the battery, short the CMOS reset jumper and wait a while (like a minute or two for the first boot) after a few trial it booted and could see the 32 Gb in the bios
I tried to use the webbios of the LSI card but I dont see the press ctrl-H during the BIOS. but when ubuntu booted i could see the LSI card in the PCIe device. I never used it before but it was also posible to control the card from the OS via a script from broadcom (https://www.broadcom.com/support/knowledgebase/1211161500661/installing-megacli-in-debian-or-ubuntu) I installed MegaCli64 and can list the drive but can't create a pool. I'm trying again with storcli but had no time to experiment more.
I installed a stock Ubuntu server on the SSD with SSH.
from there I installed docker, ZFS, pihole + pivpn, dynddns it's close from the instruction on another NAS build i did ( ARM based)
