The API is designed to be similar to a server client in TCP. It has functions like rdma_connect, rdma_accept, rdma_bind, and rdma_listen. It also has verbs specific API like rdma_create_qp and rdma_post_send. The API also has an event channel it's created in the beginning of the...

RDMA verbs编程有一堆的新概念,跟socket编程迥异。使用verbs编写一个简单的echo server/client程序需要200行以上,流程十分繁琐。 阿里的数据中心网络部署 阿里数据中心网络是基于以太网的clos网络,由三层交换机组成,分别是spine、leaf、ToR,拓扑如下: 每个ToR下面有40个节点,每台机器有一张双口网卡,上联两台ToR。
