Hi All, I think that NVMe userspace target is supported in all RDMA forms. Basically the RoCE version 1 & 2, iWARP. So the config file has Listen RDMA and a IP address. So does this mean that it does not support RoCE version 1? As RoCE version 1 is in Ethernet Layer. Thanking You, Param

Virtual Subsystem Support

by Kumaraparameshwaran Rathnavel

Hi All, I find that 16.08 release does not support virtual subsystem. But the latest code has it and I find that code is getting updated frequently. So do we have any stable code commit that supports Virtual Subsystem so that I don’t need to change my code base frequently. I need the virtual subsystem to be implemented. Thanking You, Param

by Raj (Rajinikanth) Pandurangan

Hello All, I have 100Gb Mellanox NIC and trying to setup userspace nvmf-target. Has anyone faced issues with userspace mlx5 driver?

Parse Subsystem

by Kumaraparameshwaran Rathnavel

In the function spdk_nvmf_parse_subsystem the function nvmf_create_subsystem is called first which means that function calls spdk_get_io_channel is called for each space. But the namespaces are added only after this function call to the subsystem. How does this work? Thanking you, Param

DPDK

by Kumaraparameshwaran Rathnavel

Hi All, I am writing an application similar to nvmf target in SPDK. I should not use the Makefile format given for nvmf target. I am having my own cmake file and I have included libraries and header files from DPDK and SPDK. My application core dumps at rte_mempool_create. When I use the same code and the format of the Makefile in nvmf target it doesn't. I can see that I am missing some flags r something. Can any one help me? Is there an implementation of Makefiles of nvmf target in SPDK with cmake Thanking you, Param

Re: [SPDK] NVMF target in the virtualbox

by Alex Bowden

I tried Softiwarp with SPDK and was able to get the target to start, but I couldn't get the Linux initiator to work with it. See: https://github.com/slowfranklin/softiwarp -Alex
