More Efficient and Faster Way to Send Data with RDMA Over Converged Ethernet (RoCE)
The HPE Ethernet 10/25Gb 2-port SFP28 CX4121B Adapter bypasses the TCP/IP stack and removes a data copy step reducing overall latency to deliver accelerated performance for applications such as Microsoft Hyper-V Live Migration, Microsoft SQL and Microsoft SharePoint with SMB Direct.
Reduces the impact of overlay networking on host performance with tunnel offload support.
Auto negotiates to 10GbE for immediate future proofing.
Lower Latency and Higher Throughput With Messaging Accelerator (VMA)
The HPE Ethernet 10/25Gb 2-port SFP28 CX4121B Adapter reduces system latency for improved performance specifically for high-frequency trading operations while maintaining high message rates and hundreds of simultaneous connections.
Contains VMA, an included firmware with many benefits such as lower latency, higher throughput, improved CPU utilization and minimal buffer copies between user data and hardware.
