I have Veeam immuatble backup servers in place (Ubuntu, software raid) that currently uses spinning drives. I'd like to move to RAID NVMe drives, again using Linux software RAID. Does the EC-P4BF support Linux RAID? And does the bifircation requirement hevily impact throughput? Im not looking for some insane throughput numbers like you would see on the Sabrent APEX cards but would like to see significantly higher throughput than what I see currently on RAID 10 going to 7200RPM SATA drives.
Thanks for any information and advice.

@robertd As long as the motherboard supports PCIe bifurcation, it passes the lanes through and is transparent to the system. This means it works with software RAID. Bifurcation in this case would have to be x4/x4/x4/x4 which is not supported on all systems. The peformance overhead is directly not significant but real impact depends on the system's hardware and configuration. If you need on-AIC switching we have the EC-P3X4, although this is bandwidth-limited. That one also works with software RAID as the chip is a PCIe switch. This introduces a very small amount of latency, on the order of 100-150ns.
