No. If SAS A & B is connected as per below picture, then you need to have a integrated storage controller on slot 3 of below picture. Can you check that.
Below are list if integrated storage controller which is supported in R720
TY8F9
ASSY,CRD,CTL,H710P,1GB,NV,MCRD
5CT6D
ASSY,CRD,CTL,H710,512,NV,MCRD
K09CJ
PWA,CTL,SAS,H310,MCRD
If you want to use embedded S110, you can try connecting as per figure 3 of the link. As this is not a supported configuration for 8 X 3.5 backplane it is not validated and I can not guarantee that it will work. For this you need to use cable with part# MPXC8
Can you check the connectivity of backplane. You can refer "Figure 1. Removing and Installing the 3.5 Inch (x8) SAS/SATA Backplane—PowerEdge R720" and "Figure 2. Cabling Diagram—3.5 Inch (x8) SAS/SATA Backplane—PowerEdge R720" for connectivity details for 8 X 3.5 drive backplane. 8 X 3.5 backplane also need integrated storage controller card to be installed on the server
Hard disk removal from the backplane are detected by the server (message on the digital screen on front panel), suggesting to me that the backplane are well connected?
Both SAS cables are connected to the motherboard like figure 2.
I have no other controller that the embedded S110 storage controller, but it should do the job?!
You need to have a integrated storage controller connected to slot 3 as per that diagram. S110 can not detect drives in this configuration. Only 4 drive system ("Figure 3. Cabling Diagram—3.5 Inch (x4) SAS/SATA Backplane—PowerEdge R720") support S110 in R720.
So you mean that I will have to connect SAS A cable to another motherboard connector and use slot 3? My current configuration is a 8x 3.5 backplane, and SAS A & B cables are connected like figure 2 in the documentation you provided.
I've installed a DELL PERC H710 Mini Mono RAID Controller - 512 MB Cache 5CT6D, and now I can see both SSD hard drives ! Thank you for your help Shine !
Meanwhile, I have another message during Boot process, linked to a PERC battery - should I order some additionnal part (battery)?
Can you check whether H710 you connected have a battery on it. If it have a battery then you can give some time to see whether it is getting charged and error goes away after some time.
If not you need to connect a battery to remove that warning. 70K80 is the part number of battery for H710.
