DL360 G10 - Single RIser and 2 x Dual Port Ethernet cards

Hello,

Will the following configuration work - willl the bus on the riser support it:

DL360 G10 with a single CPU and single riser

2 x  HPE Ethernet 10/25Gb 2-port 640SFP28 Adapter - in PCI slots or riser

1 x HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 Adapter in FlexLOM port

I'm concerned that the single riser may not have the bandwidth to support the 2 x 25G PCI cards together

Any help would be greatly appreciated

Regards
