dell poweredge c6100 not detecting hdds

i have a dell c6100 that doesnt detect any sas drives, it detects usbs but nothing on the sas. not showing in bios and all you get is a solid green led on the backplane board. im using dell constellation ES 9yz264-150, any help would be great.

ok, so a few things i want to mention, first is its working now, the issue was not having the mezzanine card, now  it recognizes and boots as it should, for those who may be wondering, i was able to test out a few different operating systems, and i found that windows 10, linux debian and ubuntu and redhat all work fine as well as windows server 2012 server edition, when testing windows server 2019, windows 11, and some distros of linux like linux mint, i found to either not work at all, or be very unstable. my setup is the dell poweredge c6100 with 4 nodes, with the mezzanine sas/sata controllers, and each node having 11/12 ram slots populated. or 176gb of ram each node. these nodes are configured with 3x tb sas hdds per node and run well. the only issue i found was without proper drivers for the mezzanine card, it would have very slow read/write speeds and always show at 100% disk utilization. overall id recommend this server for a budget game server and or website hosting, as parts for these machines are fairly cheap, and price to performance is very good. hope this helps.

Hello,

let’s make sure the SAS cables are properly connected to the drives and the backplane. We need to check that there are no loose ends or damage to the cables. If we suspect a drive issue, we should test the system with SAS drives that we know work well. Sometimes a failing drive won’t be detected by the system. Even if there’s a solid green LED on the backplane, it doesn’t mean all drives are recognized. An outdated BIOS and PERC can cause issues with drive detection, so you can check the latest BIOS and PERC update for the C6100 and update it if needed. 

Hope that helps!

@DELL-Erman O​ these drives are known good. all the cables seem to be connected. do i need a raid card to use sas? currently im using the intel onboard drive controller. if its the bios, may you provide a link to the download for the bios? are my drives compatible? they are 7.2k rpm 1tb sas drives. ive tried a sata 1tb also and same result.

sure you can reach latest version here https://dell.to/4afzWIt  But don't update the recent one if your version is too old. If your current version is too old, click Other Available Versions. You should update step by step. If you addressed INTEGRATED INTEL ICH10R SATA RAID it seems it does not support SAS (https://dell.to/3wBYLAA

 Unfortunately I can't be sure that drive is compatible. I was searching C6100 spare parts but it's very old and I can't reach it regarding page.

If I need to give general information C6100 supports 

Drive Bays and Hard
Drives 24 x 2.5” or 12 x 3.5” hard drive options
2.5” SAS (10K RPM): 146GB, 300GB
2.5” SATA II (7.2K RPM): 160GB, 250GB, 500GB
2.5” SATA SSD (SLC): 50GB
3.5” SATA (7.2K): 250GB, 1TB
3.5” SAS (15K): 146GB, 300GB
