RDMA
Connectivity
DEFINITION
Remote Direct Memory Access is a technology that allows direct memory access from the memory of one computer into that of another without involving the CPU.
OVERVIEW
RDMA technology provides a mechanism for transferring data directly between the memories of two systems, allowing for efficient and high-speed data exchange. This capability is crucial for applications requiring minimal latency and maximum throughput.
TECHNICAL DETAILS
RDMA operates by enabling network adapters to perform memory-to-memory data transfers without CPU intervention. This reduces the number of data copies and context switches required, resulting in faster data transfer rates and lower network latency.
COMMON USE CASES
- Enhancing the performance of distributed databases and storage systems.
- Facilitating real-time data processing in scientific computing applications.
- Reducing latency in financial trading systems and other time-sensitive applications.
