MCX512A-ACAT Ethernet network interface card provides two ports of
25GbE connectivity, 750ns latency, up to 75 million messages per
second (Mpps). For storage workloads, the 25 Gigabit Ethernet
adapter card delivers a range of innovative accelerations, such as
Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch,
and NVMe over Fabric target offloads to reduce CPU resource
consumption and drive extremely high packet rates and throughput.
This boosts data center infrastructure efficiency and provides the
highest performance and most flexible solution for Web 2.0, Cloud,
Data Analytics and Storage platforms.
