RDMA (remote direct memory access) is short for remote memory direct access technology. It features high bandwidth, low latency, zero copy, operating system bypass, and cpu uninstallation. RDMA implementation requires specific hardware support, mainly including Infiniband, iWARP and RoCE. RDMA technology is often used in high-performance computing (HPC), cluster databases, financial systems, distributed environments, and big data. This article mainly

At present, it is difficult for the data center to cope with the pressure of massive data. The development of next-generation data centers has become an imminent task. What kind of standardization can meet our data needs? Heterogeneous Networks in traditional data centers After years of development and transformation, data centers have become the heart of enterprise IT systems. However, with the development of enterprise informatization and the explosive growth of information, data centers are f

workload of the system. Generally, Web Server Clusters, database clusters, and Application Server Clusters belong to this type.A server Load balancer cluster is generally used as a web server or database server for network requests. When receiving requests, the cluster can check and accept servers with fewer and less busy requests and send requests to these servers. From the perspective of checking the status of other servers, Server Load balancer is very similar to the fault-tolerant cluster.

Server Load balancerCluster:This allows tasks to be evenly distributed among different computers in the cluster, making full use of the Cluster's processing capabilities to improve the processing efficiency of tasks. In practical applications, these cluster types may be used together to provide more efficient and stable services.For example, in a networkTrafficA server Load balancer cluster contains a high-availability network file system and a high-availability network service.
