ISER is an industry standard protocol, which uses RDMA technology to eliminate network processing overhead, while maintaining full compatibility with the widely used iSCSI protocol. Therefore, it can enjoy the proven stability, elasticity, security, high availability and recovery advantages of iSCSI, which makes it an enterprise-class storage network solution. ISER uses high-performance RoCE (RDMA based on converged Ethernet) network card on ordinary Ethernet without lossless configuration. This enables cloud computing, storage and enterprise customers to deploy iSER more quickly and easily, while accelerating application performance, improving overall infrastructure efficiency and reducing costs.
