Hi, For M630  a controller is a must  and this is what S130 supports:   [URL]   The PERC S130 controller supports the following physical disk type:
I have a Dell VRTX with M630s installed.  All of the SAS drives on the VRTX backplane work fine, no issues there.  But I had a few spare disks I put directly into one of the two 2.5" slots on the M630 nodes and the green LEDs light up and shows activity.  but when I login to the iDRAC for the M630s, the Storage portion gives an error of: "  RAC0501: There are no physical disks to be displayed. 1. Check if the host system is powered off or shutdown. 2. Check if the physical disks are inserted into the enclosure or attached to the backplane. 3. There are no out-of-band capable controllers detected." I tried each of the 3 nodes and get the same results on each one.  i checked and none of the M630s have a PERC card installed, so I thought that explains it and almost put it out of my mind.  However, when I pulled the SAS drives back out I get the flashing yellow status light on the M630s and I noticed the HDD cage has a ribbon cable connected to the motherboard labeled "MB" -- so I wondered if it could still detect the drives and use them, just not in any sort of RAID configuration, or if the PERC cards are required to use the disks in ANY way on the M630s.
