There are many PCI configurations. The Dell R750 can hold up to (6) GPUs with access to up to 8 PCIe Gen 4.0 slots. Many drive configurations support Dual PERC controllers. Either 2 fPERCs or 1 fPERC and 1 aPERC.
With so many configurations its hard to explain them all, please view the tech manual below for more detailed information about each configuration.
For example, If you want to install 16 NVMe drives on the 16 Bay Chassis. You will have to install Configuration 7. This is the only configuration where the Paddle cards are installed. These Paddle Card provide the extra PCIe lanes needed for the Direct attached NVMe Configuration.
