## Summary description

Intel E40GQSFPSR is a network interface card (NIC) designed for LAD market applications, featuring 40 Gigabit Ethernet connectivity via QSFP form factor and quad‑port capability. It serves high‑throughput server and switch uplink scenarios, enabling multi‑lane 40GbE links, low‑latency packet processing and integration into data center networking environments.

## Long description

The Intel E40GQSFPSR is a quad‑port 40 Gigabit Ethernet network interface card in QSFP form factor, intended for LAD segment deployments. It provides four 40GbE capable ports for server or switch uplinks and is designed to support high‑throughput, low‑latency packet processing in data center and carrier environments. The NIC integrates with common operating systems and virtualization platforms used in rack servers and networking appliances, enabling multi‑lane 40GbE connectivity and efficient handling of heavy traffic loads.
Advantages
The card delivers four independent 40GbE interfaces in a single QSFP module footprint, reducing port density and cabling complexity while enabling high aggregate bandwidth. It supports offload features and hardware acceleration to lower CPU utilization for packet processing and improve latency. The design is focused on stability and compatibility with standard network stacks, offering predictable performance for uplink and spine-leaf topologies in data centers.
Suitable for
Server uplinks to aggregation switches in data center racks
High‑capacity switch or router uplinks and spine connections
Virtualization hosts requiring multiple 40GbE interfaces
Network functions that demand low latency and high throughput
Key specifications
Interface type: Quad QSFP ports supporting 40 Gigabit Ethernet
Throughput: Up to 40 Gbps per port, aggregate multi‑terabit capacity across ports
Form factor: Standard PCIe network interface card suitable for server slots
Latency and offload: Hardware packet processing and offload capabilities for reduced CPU load
Compatibility: Designed for integration with common server operating systems and virtualization platforms
How to use
Install the card into an available PCIe slot on a compatible server or network appliance following the host platform safety and electrostatic discharge procedures. Connect QSFP cables or modules to the card ports to establish 40GbE links to switches or other network devices. Ensure that the host operating system has the appropriate drivers or firmware updates installed and verify link negotiation and MTU settings to match the network configuration. Monitor interface statistics and error counters during initial deployment to confirm stable operation.
Usage recommendations
Use certified QSFP optical or passive copper interconnects rated for 40GbE and verify port speed settings in both ends of each link. For virtualization and heavy throughput scenarios, enable supported offload features in the driver settings to optimize CPU usage, and plan for adequate cooling and airflow in the server chassis to maintain performance under sustained load.
