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.
