It can act as a PCIE root as well is that correct? I assume by connecting it to the input of a PCIE switch with other disks attached downstream, but would love

It can act as a PCIE root as well is that correct? I assume by connecting it to the input of a PCIE switch with other disks attached downstream, but would love to learn more and what PCIE switches are known to work.
- mgerdts 2y agoThe models of BlueField DPUs I’ve worked with have no storage (aside from eMMC to boot the DPU) directly attached. They typically run SPDK, then SPDK block devices are presented to the host as NVMe namespaces or virtio-blk devices. If using NVMe-oF with RDMA, this can provide a zero copy IO path to remote storage. For NVMe, the devices may be presented to the host as PFs or VFs. I assume but do not know that it would be the same for virtio devices.
