HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 Adapter

Ethernet 10/25Gb 2-port 640FLR-SFP28 Adapter
Stuck in network traffic at 10Gbps? Time to take the Express Lane with HPE 25GbE Adapters. With the rise in volume of mobile data and video and the frequency in which it’s accessed, legacy technologies are struggling to handle the increased throughput and lack the capabilities to cost-effectively scale. Current approaches to managing the increasing data center traffic require higher bandwidth and are cost prohibitive, keeping organizations from easily growing as their needs grow. The HPE Ethernet 25Gb 2-port 640 FLR-SFP28 Adapter is a FlexibleLOM form factor for select HPE ProLiant Gen9 Server DL family of rack and HPE Apollo Servers that delivers high-performance solutions to Telco, services providers, financial institutions and enterprises to meet higher bandwidth demand.
