Mellanox MCX512A-ACUT Network Adapter

 

Mellanox MCX512A-ACUT Network Adapter

The Mellanox MC512A-ACUT is a member of the ConnectX-5 Ethernet Adapter Cards family. This product is equipped with two ports that provide 25GbE connectivity. It boasts a latency of 750 nanoseconds and can process up to 75 million messages per second (Mpps). The 25 Gigabit Ethernet adapter card is particularly well-suited for storage workloads due to its array of advanced accelerations, such as Signature Handover (T10-DIF) in hardware, an embedded PCIe Switch, and NVMe over Fabric target offloads. These functionalities minimize CPU resource utilization, enhance data center infrastructure efficiency, and deliver superior performance, making it an adaptable solution for Web 2.0, Cloud, Data Analytics, and Storage platforms.

Quick Specs:

• Maximum Data Rate: 100 Gbps
• 8x PCIe 3.0
• 1/10/25 Gb/s Ethernet
• NVMe over Fabric offloads
