Elastic RDMA Network Interface Overview
Updated at:2025-10-20
The Elastic RDMA Interface (ERI) is a type of elastic network interface that facilitates RDMA communication between cloud servers in a private network. With features like low latency, high throughput, and minimal overhead, ERI significantly enhances the communication efficiency of BBCs. Additionally, ERI supports elastic network interface features, offering a highly available networking solution.
Application scenarios
ERI offers the following advantages:
- Low-latency access Achieve 5μs-level communication latency, and significantly reduce CPU load from network transmission.
- Elastic high availability Support online mounting/unbinding of network interface cards, as well as flexible migration of network interface cards between servers to realize highly available networking.
- Low cost Compared to dedicated network equipment, ERI is implemented based on private networks, thus reducing operational costs.
Applicable scenarios:
- Hyper-computing cluster
- Artificial intelligence distributed training
- Database
