Thanks Liu.



Now i can run perf test using

./perf -q 1 -s 1048576 -w read -M 100 -t 10 -r 'trtype:rdma adrfam:IPv4
traddr:10.3.7.2 trsvcid:4420 subnqn:nqn.2016-06.io.spdk:cnode1'



How can I import this as a block deivce (/dev/sd? Or /dev/nvme0?? Or some
other device format), so I can use this for the application locally ?





Thanks,

-kiru

Hi Kiru,



Yes, actually SPDK nvme library already support NVM-oF initiator, please
see examples/nvme/perf as an example.

It can connect local PCI NVMe or remote NVM-oF target.

Hi,



We are evaluating the spdk-target with NVMf initiator (installing linux 4.9
only on the initator but 3.18 on the target).

This is good so for, and we do have customers don’t want to upgrade 3.18
kernel even on the initiator side.



So, Similarly do we have SPDK initiator (at user land) so I can have this
configured on 3.18 kernel ?

If we have one, any pointer to the documentation will help ?



Thanks
