This network card is a new 4-port server network card launched by Intel after 82580 (1340-T4). Its performance certainly exceeds that of 82580. It adopts PCI-EX4 design and integrates four Gigabit RJ45 interfaces. It is designed for servers and high-end devices. And its performance has been optimized so that system I/0 is no longer a bottleneck for high-end network applications. Enable fault tolerance through grouping. Traffic from the faulty port will be routed to other members of the group. There is an integrated hardware acceleration function, which performs TCP/UDP/IP verification and TCP segmentation tasks. Host processing technology can offload the accelerator and release CPU resources to process other applications. It is based on the Intel I350AM4 dual-port Gigabit Ethernet MAC+PHY of the Intel controller. Up to 86 queues of receive side scaling (RSS) can minimize CPU usage in multiple processor systems. Provide excellent server-level reliability, availability and performance characteristics. Driver support: Windows 718*, Windows XP/Vista (32 & 64 bit), Windows CE*, Windows NT*, Windows 2000 Server*, Windows Server 2003/2008 (32 & 64 bit), SCO UnixWare* 7.x, Open Unix* 8.0, Novell ODl*.Novell Netware*, SUSE Linux Enterprise Server* 9.0, Red Hat Enterprise Linux* 4.0, Linux*, FreeBSD*, Sun Solaris*, Microsoft DOS*, VMWare ESX* Product applications: lscsi, PXE diskless boot, VLAN aggregation, soft routing, ROS, load balancing, ESXI5.0/5.1, various servers, etc Each port can send and receive 8 queues Supports 8 pools (single queue) of virtual machine device queues (VMDq) for each port Supports SR-IOV function Supports Direct Cache Access (DCA) Supports Intel I/O Acceleration Technology v3.0 TSO interleaving technology is to reduce latency Minimize device I/O interrupts using MSI and MSI-X UDP, TCP and IP checksum offload UDP and TCP send segment offload (TSO) SCTP receive and send checksum offload Packet Interrupt Association Timer (Packet Timer) and -Delay Interrupt Timer are for both send and receive operations Support PCIExpress Base Specification 2.0 (5 GTS) Intel I350AM4 dual integrated MAC+PHY and SERDES chip controller has the characteristics of high performance, high reliability and low power consumption Ultra-deep, per-channel packet buffering can reduce CPU usage Hardware acceleration can offload tasks from the host processor. The controller can be used to offload TCP/UDP/IP checksums and TCP segmentation Link aggregation and load balancing Related switches: 802.3ad (LACP), normal Trunking (GEC/FEC) Switching and NIC not related Failover Prioritization - 802.1p Layer 2 priority encoding Virtual LAN - 802.1q VLAN tagging Jumbo frame (9.5KB) 802.x flow control Multicast/broadcast packet replication
