Hello The SAS connectors on the riser itself are for modular cards that are installed in the integrated storage slot on the riser. If your SAS 6/iR is modular then it does not have it's own SAS connectors. It uses the connectors on the riser. The H700 will need to be the adapter version to work in a normal PCIe slot. If it is the integrated version then it will not likely work in that slot. Cabling the controller is quite easy. There is a SAS A and SAS B connector on the backplane. You need to have a cable connection to each if you want to use all 4 slots. SAS A is for HDD 0,1 and SAS B is for 2,3. Running two internal RAID controllers to the backplane is not a supported configuration in the R410. You might be able to get it to work, but it is not something we designed to function. I would recommend using one of the cards instead of trying to use both. The white slot on the riser is an integrated storage slot. It is designed specifically for the integrated versions of our PERC cards. The black slot is a normal PCIe x16 slot. If you need more assistance then I recommend you post specifics about the controllers and cables. If you can locate part numbers on the controllers and cables you are trying to use it would be helpful.   This is not a supported config. Try using just one internal RAID controller connected to the backplane.   This could be a link tuning or training error. If you try to install an integrated storage controller in a normal PCIe slot it can cause these errors. Thanks
We're pretty new to RAID in general - and we have a R410 with a SAS 6/iR card in its storage slot - and a H700 hooked up in the PCI expansion slot. The problem is, we can only get 2 of the HDDS to recognize because we're not sure how to hook up the wires.  The H700 has 2 cables that can hook up from the back. The backplane of the hotswap device has 2 slots as well - however the riser it seems needs to be plugged in. You have the riser SAS cable plugged into the right most hotswap SAS port - and the hotswaps left port is plugged into port A of the H700.  If we plug both cables from the SAS card to the hotswap - we get an error about the riser and non detection, a fatal error of sorts. We figure its something silly we're missing or a cable we're missing - but we cant seem to find a concrete install guide and dell tech support is min $150. Any help is appreciated!
