Why each option
On the Cisco UCS C480 M5 server, PCIe slot 11 is the designated default slot for the rear RAID controller when the rear drive module is populated with SAS or SATA drives.
PCIe slot 9 is not designated as the default slot for the rear RAID controller in the C480 M5 hardware guide.
PCIe slot 10 is not the default assignment for the rear SAS/SATA RAID controller in the C480 M5 platform.
According to the UCS C480 M5 hardware installation guide, PCIe slot 11 is the factory-default and required location for the rear RAID controller card when SAS/SATA drives are installed in the rear drive module. This slot placement ensures proper signal routing and bandwidth allocation between the controller and the rear backplane. Using any other slot would require manual reconfiguration and is not the supported default.
PCIe slot 12 is not identified as the default rear RAID controller slot for SAS/SATA configurations in the C480 M5.
