Software Versions Required by Different Models

You can use elastic BMSs or ECSs as the node resources in the elastic cluster resource pool. The OSs and CCE cluster versions vary depending on the node model. This section describes the software versions required by different models, which helps you create images and upgrade software.

Remote direct memory access (RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system. RDMA over Converged Ethernet (RoCE) is a network protocol which allows RDMA over an Ethernet network. InfiniBand (IB) is a computer networking communications standard used in high-performance computing. It is used for data interconnect both among and within computers.
