1. PCIe x8 Broadcom BCM57840 four optical port 10G SFP+server optical network card controlled by Broadcom BCM57,840 chip2. BCM57840 supports the segmentation of a single 10 Gb Ethernet port into up to eight partitions, enabling dynamic bandwidth allocation to meet the workload requirements of applications, thus ensuring efficient utilization of 10 GbE links.3. BCM57840 converges a flexible motherboard LAN networking solution for 10 Gigabit server networks. It supports NIC zoning of the switch, allowing administrators to divide a single network port into up to four zones and allocate bandwidth as needed.4. High performance - provides the highest level of performance for mission critical enterprises and -scale data centers.5. NIC zoning - Helps manage 10 GbE bandwidth allocation for virtual machines and applications.Applicable network: 10 Gigabit EthernetMain chipset: Broadcom BCM57840Bus type: PCI X8Transmission medium: 4 x SFP+optical fiber LCTransmission rate: 10000MbpsNetwork function: Under low CPU utilization, it can take advantage of on-site verification support for L2 networking, TCP/IP offloading, iSCSI HBA offloading and FCoE HBA offloadingOperating temperature: 0 C to 55 CApplication fields: for cloud and Web2.0 data center server, enterprise data center server, private cloud, machine learning (ML) cluster, high-performance computing (HPC) cluster, multi node container platform, NVMe storage decompositionOperating system: Windows Server 2016/2012 /2012/2008 /2008/2003 /2003, XP , Windows 10/8/8.1/7/Vista, Linux Stable Kernel version 3. x, 2.6, x, Red Hat Enterprise, Linux 5, 6, SUSE Linux Enterprise Server 10, 11, FreeBSD 9, VMware ESX/ESXicolor:GreenMaterial:PCB+MetalPackage Contents:1 x PCI-E BCM57840 four optical port server network card1 x Short baffleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
