Why choose it

The X710-DA2 offloads CPU-intensive tasks like checksum computation and packet segmentation, freeing processor cycles for application workloads. Its RDMA support (iWARP and RoCEv2) accelerates storage traffic, while SR-IOV and VMDq enable efficient virtual machine networking. The OCP 3.0 form factor simplifies deployment in compatible servers, and SFP+ cages provide flexibility to use a wide range of optical or copper modules.

Ideal use cases

• Virtualized server environments requiring high VM density
• Software-defined storage and hyper-converged infrastructure
• High-frequency trading and latency-sensitive applications
• Cloud and web-scale data centers

Good to know

The adapter includes both low-profile and full-height brackets, ensuring compatibility with various server chassis. It supports advanced management via NC-SI, allowing out-of-band monitoring and control. With a modest 10.6 W TDP, it balances performance with energy efficiency.
