High performance network adapters are designed to provide fast and efficient data transfer between servers, storage systems, and other devices in a data center or high-performance computing environment. They typically offer advanced features such as high bandwidth, low latency, RDMA support, and offload capabilities for tasks such as encryption and compression. These adapters are often used in high-performance computing, cloud computing, and data center environments to support large-scale workloads and high-speed data transfer. Some examples of high-performance network adapters include:

High-performance network adapters typically use specialized protocols that are designed to provide low-latency and high-bandwidth communication between systems. Some examples of these protocols include:
- Remote Direct Memory Access (RDMA): A protocol that allows data to be transferred directly between the memory of one system and another, without involving the CPU of either system.
- RoCE (RDMA over Converged Ethernet): An extension of RDMA that allows RDMA traffic to be carried over Ethernet networks.
- iWARP: A protocol that provides RDMA capabilities over standard TCP/IP networks.
- InfiniBand: A high-speed interconnect technology that provides extremely low-latency and high-bandwidth communication between systems.
These protocols are typically used in high-performance computing (HPC) environments, where low-latency and high-bandwidth communication is critical for achieving maximum performance. They are also used in other applications that require high-speed data transfer, such as machine learning, data analytics, and high-performance storage systems. Some examples of adapter features include:
- Advanced offloading capabilities: High-performance adapters can offload CPU-intensive tasks such as packet processing, encryption/decryption, and compression/decompression, freeing up server resources for other tasks.
