Intel PCIe 3.0 x8 - 25 Gigabit SFP28 x 2 Network Adapter

Overview

The Intel XXV710DA2OCP1 is a dual-port network adapter designed to deliver high-speed connectivity for servers requiring robust data transfer capabilities. It provides two 25-gigabit Ethernet lanes via a PCIe 3.0 x8 interface, enabling up to 50 Gbps aggregate throughput. This adapter is ideal for accelerating storage traffic, east-west application communication, and backup operations in demanding data center environments.

Key features

• Two independent 25 GbE SFP28 ports that support both direct-attach copper cables and SR optical transceivers, offering flexibility in cabling and deployment.
• PCIe 3.0 x8 host interface ensures sufficient bandwidth to fully utilize each port’s 25 Gbps speed without bottlenecks.
• Intel virtualization technology combined with PCI-SIG SR-IOV enables multiple virtual machines to share the adapter efficiently while maintaining near-native throughput and low latency.
• Native support for storage protocols like iSCSI and NFS simplifies network design and optimizes storage traffic handling.
• On-chip quality of service and traffic management features prioritize critical packets to maintain consistent network performance even under heavy load.
• Designed to meet the needs of cloud clusters, enterprise data centers, and high-performance computing setups requiring reliable, low-latency connectivity.
