hello i have a supermicro X9DRi-LN4F+ Motherboard with dual 10 core cpus. im using a dell branded perc H700 raid controller with 3 seagate 4TB 5400RPM sata drives. i have the drives all set as 3 separate 4tb raid 0 drives, raid controller says smart data is fine for each drive. however when i reboot the machine the raid controller bios does show 3 virtual disks but once i get past the missing raid battery error the motherboard just sits there with a constant beep however if i remove the sas cable and leave the pcie raid controller card plugged into the mobo she boots any idea whats goin on?
why is my perc H700 beeping?

I think Dell uses the SMBus on the H700 to send fault signal to the motherboard BMC in a Dell server. The card might be sending that same fault signal to the SMCI motherboard and it doesn't know what to do with it. SMCI motherboards sometimes have jumper for SMBus on PCIe that you can use to disable the SMBus and that might block the signal. Check user manual for that m/b to see if that's an option. Or, you could tape the SMBus pins on the H700 card.
Thanks. I did a search and page 2-35 and onwards show the jumpers but there doesn't seem to be a jumper for SMBus on PCIe. So, I think your only option is to tape the SMBus pins. Some Supermicro boards had a jumper for that, but I guess not this one.
pins 5 and 6 on my H810 solved the SM Bus boot loop issue as described here
Sounds same for the 710 - probably common to all the cards. tape is not permanent anyway if it doesn't work.
