“for connected target devices”, do you mean NVMeoF initiator device uses the verbs API that go through the kernel ? If so, yes, this will go through kernel.

I don’t know whether someone  tried Rocksdb on NVMeF device or not.

I believe “for connected target devices” that will go through kernel,

Without doing “nvme -> uio_pci_generic”, it will go through kernel. How do we specify connected target devices in “etc/spdk/rocksdb.conf.in” and use rocksdb?

Thanks

Hi Ram,

SPDK has already NVMeoF initiator, you can see the examples/nvme/perf.c, it can support both local NVMe device and remote NVMeoF target.

I don’t think so but want to ask that Can connected target devices be treated as local nvme for spdk to work as initiator? Is there any near term plan to support SPDK host initiator?

I appreciate your response.

On side note: when can we get spdk conference presentations?

Thanks
Ram
