This Fujitsu-certified dual-port 10 Gigabit Ethernet SFP+ adapter, based on the Intel X710-DA2 chipset, is the most commonly ordered network expansion card for PRIMERGY rack and tower servers. Designed as a PCIe 3.0 x8 card, it delivers 20Gbps aggregate network throughput per slot, making it suitable for 10GbE server connectivity to ToR (top-of-rack) switches in VMware, Hyper-V, and bare-metal Linux environments. The adapter supports SR-IOV (Single Root I/O Virtualization) with up to 128 Virtual Functions (VFs) per port, enabling near-native network performance for VMs in virtualized environments.
The Intel X710 controller provides advanced offload capabilities including large send offload (LSO), large receive offload (LRO), TCP/UDP/IP checksum offload, receive-side scaling (RSS), and RDMA over Converged Ethernet (RoCEv1/v2) for iWARP and RDMA-enabled storage or MPI workloads. The SFP+ ports accept direct-attach copper (DAC) cables, active optical cables (AOC), and 10GBASE-SR/LR fiber transceivers, providing installation flexibility in both short-reach (850nm SR) and long-reach (1310nm LR) data center scenarios.
Fujitsu validates and maintains driver support for this card through its ServerView Drivers and Tools package, ensuring tested compatibility with all current PRIMERGY generations and operating systems. The card is a high-demand catalog SKU because virtually every 10GbE PRIMERGY deployment requires at least one unit, and its SR-IOV support makes it the standard choice for NFV (Network Function Virtualization) deployments as well.
