Hello Everyone,

 

Noob alert 🙂 I just built my unRaid server with the following configuration - 

 

SUPERMICRO MBD-X13SAE-F-O Motherboard

Intel Core i5-13600K 

Supermicro (Micron) 32GB 288-Pin DDR5 4800 (PC5-38400) Server Memory (MEM-DR532L-CL01-EU48) X 2

Corsair RM750e Power supply.

Case : HL15 (i really liked this case, since i am going to keep in a open rack spend the extra $)

 

My HL15 comes with 4 Mini-SAS-HD cable from the backplane. I want to connect 10 HDDs so got this HBA card - LSI 9300-16i 16-port (flashed to IT mode). Was hoping i can run all drives with this single card. 

 

This card needs x8 lane, PCIe 3.0 so connected to SLOT 4 which is PCIe 5.0 x8 (IN x16) Slot. In the BIOS i am able to see the LSI card and the HDD attached with them, but unRaid doesn't show the HDDs. I moved the LSI card to SLOT7 which is a PCIe 5.0 x16 Slot. And I am able see the HDDs in unRaid.

 

I want keep SLOT 7 for Graphics card in the future. Am I making any basic mistake here? I even changed the SLOT4 speed to Gen 3 and still no luck.

 

Can someone please help? What is the right way to use this LSI card? should go and get 8i card and use SATA for rest of the drives?

With slot 4 in use, slot 7 will also be x8, so it doesn't really matter which card is where, as long as both work together when you get the GPU.

Thank you, I saw this in the manual, are you referring to this. I had my doubts as well

 

 

Couple more questions - 

1. In terms of using a 16 drive LSI card should i downgrade to 8 drive and use SATA ports for rest of HDDs. I saw in few posts on how hot these HBA cards can run. 

2. If i connect the HBA card to PCIe 5.0 x16 slot (CPU SLOT7), do i need to connect aux six pin power as well?  This card needs around 27w, connecting aux power will keep the drives stable or just run off pcie?

 

Thanks again

You can, and performance will be similar, but the 8i model still needs some cooling, though it uses about half the power.

Should not be needed, PCIe slot is good for 75w

Thank you, appreciate the input. Still can’t figure out why slot 4 is not working. Will move the card to slot 7 and call it a day
