The PERC 5 is not supported on the R610.  You need the PERC 6/i.  The PERC 5 might work, but you can't use it in the dedicated storage slot; you will need to try a different PCIe slot.
Hi everyone,  I am looking to get RAID 5 capabilities in an old R610 we have laying around. The new controller appears to be compatible with the server, and is known good. Every time I boot the server with the new Perc 5i card it gives me:  "Invalid pcie card found in the internal storage slot. System Halted!"  Is there a step to this process that I am missing? This is my first time trying to do anything like this, and am getting beat up. If I put the old controller back in or no controller at all it boots without problem. I have updated the BIOS to Dell Server BIOS R610 Version 6.4.0.   Any advice would be greatly appreciated.
Looking to replace an older RAID controller (UCS-61) with a newer Perc 5i 
(UCP-51) in a PowerEdge r610...
