Сетевой адаптер HP nc552sfp 10Gb 2-port Ethernet

Сетевой адаптер HP NC552SFP 10Gb 2-port Ethernet Server Adapter в отличном внешнем и техническом состоянии Трансиверы HP 10Gb SR SFP+ 455885-001 опционально, можно добавить в комплект Product Number: 614201-001 Spare Number: 614506-001 RMN: HSTNS-BN62 Совместимость: HP ProLiant DL/ML/SL G6/G7/G8/G9 Performance Dual-port 10 Gigabit Ethernet throughput The 20,000 Mb/s full duplex Ethernet transfer rate per port (40 Gb/s aggregate full duplex). 10 Gigabit Ethernet bandwidth. PCI Express interface An eight lane (x8) PCI Express bus based on the PCIe v2.0 standard. The adapter is backward compatible with four lane (x4) PCI Express, automatically auto-sensing between x8 and x4 slots. Jumbo frames Permit a 9,000 byte transmission unit (MTU). Supports 9KB jumbo frames. SR-IOV Supports industry standard SR-IOV (Single Root Input Output Virtualization). SR-IOV reduces CPU overhead when sharing networking resources between numerous virtual machines. The NC552SFP hardware is capable of SR-IOV, requires firmware, software and OS support. TCP stateless offloading For overall improved system response, the NC552SFP adapter supports standard TCP/IP offloading techniques including: TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the network adapter. Large Send Offload (LSO) or TCP Segmentation Offload (TSO) allows the TCP segmentation to be handled by the adapter rather than the CPU. Interrupt coalescing Groups multiple packets, thereby reducing the number of interrupts sent to the host. 802.1p QoS tagging IEEE quality of service (QoS) 802.1p tagging allows the adapter to mark or tag frames with a priority level across a QoS-aware network for improved traffic flow.
