Thanks Walker,
I am able to get the nvmef_tgt started. I am working on porting/upgrading
the latest linux kernel (4.8) on my another host.
I will get back to you if I have any challenges in connecting to the nvme
target.

Thanks

You can run the identify or nvme_manage example to get a nice list of all of
the devices that SPDK can attach to. They are in examples/nvme.

We have this page: http://www.spdk.io/spdk/doc/nvmf_getting_started.html,
which is accurate for our last tagged release but has gone stale for the
code on 'master'. We'll have an updated one shortly.
Right now it's fairly early stages, so you mostly have to just read the
code. Our configuration file is reasonably well documented too.

We test against the NVMe-oF initiator that will be added to the Linux
kernel. It currently exists as a set of patches against kernel 4.8. Here is
an article from Mellanox explaining how to set up your Linux kernel for
NVMe-oF: https://community.mellanox.com/docs/DOC-2508. SPDK can run against
essentially any modern Linux kernel, so you only have to put kernel 4.8 on
the initiator system.
