Fiber Gigabit PCI Express x4 Adapter The DGE 560SX Fiber Gigabit PCI Express x4 Adapter is a high performance network card that lets businesses take advantage of the PCI Express PCIe slots of their servers to enhance network performance with fiber optic connectivity. The PCIe architecture ensures dedicated inputoutput IO bandwidth for the adapter44 ensuring high performance without bus sharing for Gigabit Ethernet connectivity in fiber optic networks.PCI Express Interface The DGE 560SX supports 2Gbps transfer rate between the adapterTs board and the server host. It provides unsurpassed robustness44 reliability and performance44 and is the optimum IO connectivity solution for a wide spectrum of server44 storage and system area networks SAN. As a successor to the PCI and PCI X interfaces44 the PCI Express serial bus eliminates many of the inefficiencies of parallel PCI and PCI X architectures. With lower pin counts and lower power consumption requirements44 the DGE 560SX adapter also reduces system power requirements. PCI Express is backward compatible with PCI and PCI X addressing44 which allows all existing applications and Operating Systems to function unchanged.Fiber Optic Connection With fibre optic cable44 distance can reach up to 550m and network speed 2000Mbps full duplex. The adapter offloads the host operating system overhead by providing on board verification of IP header and TCPUDP checksum for data received44 in turn freeing up server processing power for other applications.VLAN amp QoS Support The DGE 560SX adapter provides on board screening of VLAN tagged Ethernet frames compliant with IEEE 802.1Q. This allows the server to operate in a flexible and secure network configuration in a standards based environment. The adapter supports 802.1p Priority Queues for improved delivery of delay sensitive data such as voice and video. The DGE 560SX supports other advanced features such as Jumbo frames of up to 9KB and Promiscuous mode. It supports ACPI Ad
