Server Network Card 1G (10/100/1000), 2x SFP two SFP ports (Intel I350 Based)
You can use any SFP transceivers (do not need to reprogram the SFP for Intel).
2x SFP+ 1G is a PCIe x4 1Gbps Dual-Port SFP Sever Fiber Ethernet Adapter based on Intel I350 chipset, compatible with PCIe x8 and x16 slot. The adapter is mainly used on a server workstation and its performance has been optimized while being designed, which makes system I/O no longer be the bottleneck on the application of high-end network. The adapter can be grouped up together through its two or four ports to expand network bandwidth and ensure network performance. It can also real-time detect automatically and combine the communication route from the faulty port with others to achieve high-performance communications incessantly.

Overview
The new 1,&-2SFP builds on Intel’s history of excellence in Ethernet products. Intel continues its market leadership with this new generation of PCIe* GbE network adapters. Built with the bridgeless Intel® Ethernet Controller I350, these adapters represent the next step in the Gigabit Ethernet (GbE) networking evolution for the enterprise and data center by introducing new levels of performance through industry-leading enhancements for both virtualized and iSCSI Unified Networking environments. This new family of adapters also includes new power management technologies such as Energy Efficient Ethernet (EEE) and DMA Coalescing (DMAC).
Flexible I/O Virtualization
The 1,&-2SFP includes Intel® Virtualization Technology for connectivity (Intel® VT-c) to deliver I/O virtualization and Quality of Service (QoS) features designed directly into the controller on the adapter. I/O virtualization advances network connectivity models used in today’s servers to more efficient models by providing Flexible Port Partitioning (FPP), multiple Rx/Tx queues, and on- controller QoS functionality that can be used in both virtual and non-virtual server deployments. By taking advantage of the PCI-SIG SR-IOV specification, Intel® Ethernet products enable Flexible Port Partitioning (FPP). With FPP, virtual controllers can be used by the Linux* host directly and/or assigned to virtual machines. With this port partitioning, administrators can create up to eight dedicated connections on a single Ethernet port for use in bare-metal and virtualized server deployments. In a bare-metal Linux server, host processes can be assigned to dedicated network resources to provide traffic isolation and balanced bandwidth allocation. In a virtualized environment, a VM can be assigned to a virtual controller to reduce the CPU overhead seen when using a software-based network bridge by offloading network traffic management to the controller.
Scalable iSCSI Performance
An 1,&-2SFP with native iSCSI initiators built into Microsoft* Windows*, Linux*, and VMware* ESX platforms provides a simple, dependable, cost-effective way to connect to iSCSI SANs. These native initiators are broadly tested using multiple generations of operating systems, storage systems, and OS tools to help ensure reliability and ease of use. Standardizing on Intel® Ethernet Adapters for iSCSI enables administrators to use a single initiator, TCP/IP stack, and a common set of management tools and IT policies. In addition, Intel® Ethernet Server Adapters include a number of hardware features designed to accelerate iSCSI traffic and enhance data processing. For example, TCP segmentation offload and checksum offload capabilities help reduce processor usage, increase throughput, and deliver exceptional iSCSI performance. Finally, using native OS initiators, an 1,&-2SFP supports the CRC-32 digest instruction set included with Intel® Xeon® processor products, which improves transmission reliability and delivers an enterprise-class iSCSI solution.
Power Management Technologies
Today, companies everywhere are looking for ways to decrease energy consumption across the enterprise to reduce costs and environmental impact, while at the same time solving increasingly important power density challenges. That’s why Intel has introduced new, advanced Power Management Technologies (PMTs)with the 1,&-2SFP that enable enterprises to configure power options on the adapter and more effectively manage their power consumption.
Energy Efficient Ethernet (EEE)
The 1,&-2SFP supports the IEEE802.3az Energy Efficient Ethernet (EEE) standard so that, during periods of low network activity, EEE reduces the power consumption of an Ethernet connection by negotiating with a compliant EEE switch port to transition to a low power idle (LPI) state. This reduces the controller power to approximately 50% of its normal operating power, saving power on the network port and the switch port. As soon as increased network traffic is detected, the controller and the switch quickly come back to full power to handle the increased network traffic. EEE is supported for both 1000BASE-T and100BASE-TX.
DMA Coalescing
Another power management technology that can reduce power on the server platform is DMA Coalescing (DMAC). Typically, when a packet arrives at a server, DMA calls are made to transfer the packet within the server. These calls wake up the processor, memory and other system components from a lower power state in order to perform the tasks required to handle the incoming packet. Based on the configurable DMAC settings, incoming packets are buffered momentarily before any DMA calls are made. This enables the controller to intelligently identify opportunities to batch multiple packets together so that when components are wakened from lower power states they can efficiently handle the batched packets at the same time. This enables platform components to remain in lower power states longer, which can dramatically reduce platform energy consumption. DMAC synchronizes DMA calls across all controller ports to ensure maximum power savings.
Software Tools and Management
Intel® Advanced Network Services (Intel® ANS) include new teaming technologies and techniques such as Virtual Machine Load-Balancing (VMLB) for Hyper-V environments. Today, Intel ANS includes a variety of teaming configurations for up to eight adapters, support for mixed vendors server adapters teaming and includes support for 802.1q VLANs, making Intel ANS one of the most capable and comprehensive tools for supporting server adapter teaming. Additionally, Intel® PROSet for Windows* Device Manager and PROset CL extends driver functionality to provide additional reliability and Quality of Service features and configuration.
