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 ...

NVMe-oF specification中新增Fabrics Command Set,用于target探测发现、连接管理等工作。 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...

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)。 测试结果包括TCP和RoCE(RDMA)两部分,上图是第一部分。我们看到,用户态SPDK to SPDK的512Byte小块读测试达到了41.5M(超过4100万)IOPS;Linux 5.15内核的FIO测试只...
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...
