Simple NVMe-oF Target Offload Benchmark HowTo Configure NVMe over Fabrics Target using nvmetcli Setup For the target setup, you will need a server equipped with NVMe device(s) and ConnectX-5 (or later) adapter. The client side (NVME-oF host) has no limitation regarding HCA type. ...
NVME-oF Target Offload is an implementation of the new NVME-oF standard Target (server) side in hardware. Starting from ConnectX-5 family cards, all regular IO requests can be processed by the HCA, with the HCA sending IO requests directly to a real NVMe PCI device, using peer-to-peer ...
This post shows how to configure NVMe over Fabrics (NVMe-oF) target offload for Linux OS using ConnectX-5 (or later) adapter. This feature is available using MLNX_OFED 4.1 or later. FW version should be 16.20.1010 or later. References Setup Prerequisite Configuration Script Example Client ...

NVMe-oF从系统运行角度分为分为Initiator端和Target端,中间通过Fabric网络连接,使用较多的RDMA transport。 RDMA Transport Layer RDMA Transport基于RDMA RC/RD模式提供可靠按需交付服务,使得Host可以利用二端的RDMA NIC进行直接数据放置而不需要经过CPU数据拷贝,从而高效的访问远端高性能nvme设备。
DPU网卡NVMe-oF极限性能测试 前不久看到一篇《NVIDIA BlueField再创DPU性能世界纪录》的新闻,其中列出了下面这个图表: 该测试环境是2台服务器,每台各安装2块NVIDIA Bluefield-2 DPU,形成4条100GbE以太网直连,两端分别跑NVMe-oF Target(存储目标)和Initiator(主机端)。
首先使用SoftRoCE来实现底层的rdma传输,然后使用SPDK来实现NVMe over Fabrics Target。.../configure --with-rdma make 3.启动NVMe-oF target # modprobe nvme_rdma # scripts/setup.sh setup会把nvme盘的驱动由...4420 客户端 1.load module # modprobe nvme-rdma 2.discovery # nvme discover -t rdma -a...
根据Spec的定义,Data在整个PDU中的最大的offload起始值是128,所以data padding的长度是有限。填充长度是根据CPDA(Controller PDU Data Align, target决定,当然是双方已经沟通好的值) 或者HPDA (Host PDU Data Align, 由host那段决定,当然是双方已经沟通好的值) 的值,构建出一个不超过128长度大小的值A,再减去(HDR...
