    PCIe switches, "Multicast" & drive mirroring.

    I haven't dealt with dedicated PCIe switches before, and I'm trying to make sense of a feature that is advertised with almost all of them: "Multicast" (from PEX 8749 datasheet) As an example, let's say I have two PCIe x4 NVMe drives in a software Raid1/mirror setup, so the drives would...
