It looks like there are a max of four PCIe SSDs supported in the R730XD. If you have a PCIe SSD backplane slots 20-23 can be used for PCIe SSDs. This is a backplane limitation not a controller limitation. You may be able to find more information in the system manual.
Thank you for your reply. The R730xd is indeed installed with a PCIe SSD Extender and four slots (20-23) are available for PCIe SSD. However, I need to make sure that a RAID 0 config is possible on the four PCIe SSD's. Am I right that the PCIe SSD Extender manage the RAID set on the PCIe SSD's? And does this PCIe SSD Extender support RAID 0 on four SSD's? Unfortunately, the PCIe SSD drives cost a lot and it is not possible to return the drives if it is not compatible.
Slots 20-23 are auto-detecting. If a SAS or SATA drive is detected then the backplane routes to the PERC. If a PCIe SSD is detected then it routes the drive to the PCIe controller. I'm fairly certain the PCIe controller is just a pass-through controller with no RAID capabilities. You would need to use some form of software RAID within the OS if you want the drives in a RAID 0.
The manual for the PCIe controller should be called "Dell PowerEdge Express Flash NVMe PCIe SSD Adapter".
