WY580F1SFP is PCI-Express X1 SFP Gigabit Ethernet network interface card .based on Intel 82580 Quad port Gigabit Ethernet MAC+PHY of Intel Controller. Performance Features: - 8 Transmit and Receive queues per port - Up to 8 queues of Receive Side Scaling (RSS) minimize CPU utilization across multiple processor systems - Support for 8 pools (single queue) of virtual machine Device Queues (VMDq) per port - Support Direct Cache Access (DCA) - Support Intel I/O Acceleration Technology v3.0. - TSO interleaving for reduced latency - Minimized device I/O interrupts using MSI and MSI-X - UDP TCP and IP checksum offload - UDP and TCP transmit segmentation offload (TSO) - SCTP receive and transmit checksum offload - Packet interrupt coalescing timers (packet timers) and absolute- delay interrupt timers for both transmit and receive operation - SFP Gigabit Ethernet: - Gigabit Ethernet Adapters with SFP cage support: 1> 1000Base-LX Fiber Gigabit Ethernet with 1000Base-LX SFP transceiver 2> 1000Base-SX Fiber Gigabit Ethernet with 1000Base-SX SFP transceiver 3> SFP (1000Mb/s) Copper Gigabit Ethernet with SFP transceiver 4> Small Form Factor Pluggable (SFP) Cage for SFP LC connectors 5> Optional SGMII mode (future support) Common Key features: - Support PCI Express Base Specification 2.0 (5 GTs) - High performance reliability and low power use in Intel 82580 Quad integrated MAC + PHY and SERDES chip Controllers - Ultra deep packet buffer per channel lowers CPU utilization - Hardware acceleration that can offload tasks from the host processor. The Controllers can offload TCP/UDP/IP checksum calculations and TCP segmentation - Server class reliability availability and performance features: - Link Aggregation and Load Balancing - Switch dependent: 802.3ad (LACP) Generic Trunking ( GEC / FEC) - Switch and NIC Independent - Failover - Priority queuing –802.1p layer 2 priority encoding - Virtual LANs –802.1q VLAN tagging - Jumbo Frame (9.5KB) - 802.x flow control - Multicast/ broadcast Packet replication - Statistics for SNMP MIB II Ethernet like MIB and Ethernet MIB (802.3z Clause 30) - Supports Vital Product Data (VPD) - LEDs indicators for link/Activity status
