Answer: A

Explanation:

With SMC-R, System z network capability takes a new leap, strengthening performance for sharing data and reducing data transmission network overhead. The new System z® RDMA over Converged Ethernet (RoCE) feature ― 10GbE RoCE Express―enables industry-standard RDMA capability on the System z platform. As an RDMA-capable network interface card (RNIC), it can transfer data using direct memory-to-memory communication, reducing the CPU overhead of the networking software stack. SMC-R provides application transparent exploitation of this new RoCE feature reducing the network overhead and latency of data transfers, effectively offering the benefits of optimized network performance across processors. This breakthrough also lowers the CPU cost associated when moving large amounts of data.
