Top 10 2 Port Ge Nic

The ST2000SPEXI PCI Express Dual Port Gigabit Network Card lets you add two gigabit Ethernet ports to a desktop computer through a single, four-lane (x4 or higher)PCI Express slot.Each port is fully compatible with IEEE 802.3/u/ab standards, for 10/100/1000 Mbps auto-negotiation.

This 2-port GbE network card is based on the high-performance Intel I350 chipset, which offers several advanced driver options including IEEE 802.3ad link aggregation / teaming support, enabling you to add additional bandwidth to your system. Support for Jumbo Frames, full-duplex operation and 802.1q VLAN tagging also aid in creating an efficient network configuration.

Also useful for virtualization applications (check your VM software for chipset compatibility) or setting up a dual-homed host configuration, this dual-port network card lets you accommodate several complex network scenarios, to meet your business needs. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

The ST2000PEXPSE Dual Port PoE NIC provides two 10/100/1000 Mbps PoE RJ45 ports that can provide up to 25.5W of power each, combining a network data connection and power on a single cable, for less clutter and convenient installations in remote locations. This full/low profile Gigabit server adapter supports the IEEE 802.3at (Type 1 and 2) standard for a Power Sourcing Equipment (PSE) device, and can deliver 48V DC power to compliant Powered Devices (PD). This eliminates the need for a separate power source and cable for remote networked devices such as IP cameras, IP phones and wireless access points. Suitable for any PCI Express-enabled client, server or workstation, this versatile PoE network adapter supports features such as Jumbo Frames, VLAN tagging and Wake on LAN (WOL). The ST2000PEXPSE PoE NIC is backed by a StarTech.com 2-year warranty and free lifetime technical support.

This 2 port PCIe network card offers versatile and cost-efficient network connectivity, by increasing the available network bandwidth without having to replace your existing cabling infrastructure. The 5-speed network card lets you add two 10G / NBASE-T RJ45 ports to your server or desktop computer and access your network at multiple speeds: 10G, 5G, 2.5G, 1G, and 100Mbps. Compatible with a broad range of operating systems, this versatile dual port NIC is ideal for many business applications that require upgrades to servers or workstations. Fully compliant with 10GBASE-T and NBASE-T specifications, the PCI Express network card is a cost-effective way to enhance your server or computer capabilities by adding two powerful 10 Gigabit Ethernet ports. (10G network speeds require CAT6a cable. All other speeds require CAT5e cable.) The dual port network card supports advanced NBASE-T technology, compatible with the latest multi Gigabit Ethernet switches and routers, such as new Cisco campus switches (including Catalyst 4500E, 3850 and 3560-CX). The card enables you to connect to NBASE-T based equipment at network speeds of 2.5Gbps or 5Gbps, over your existing Cat5e infrastructure, without having to upgrade to more expensive Cat6a. The Ethernet ports are based on the Intel X550 chipset, designed to deliver the power, performance, and enhanced capabilities you need for reliable network connections to your server or computer. The network card also supports advanced features including 9K jumbo frames and 802.1q VLAN tagging. The server NIC card comes equipped with a standard-profile bracket for installation in a full-sized chassis and includes a low-profile/half-height bracket for installation in small form-factor computers. The 2 port Gigabit network card is backed by a StarTech.com 2-year warranty and free lifetime technical support.

This dual port PCIe network card lets you add two gigabit Ethernet ports to a client, server or workstation through a single PCIe slot. Each port provides 10/100/1000 Mbps capable Ethernet and is fully compatible with IEEE 802.3/u/ab standards. Suitable for any standard PCI Express enabled system, the 2 port Gigabit Ethernet card supports full duplex flow control for maximum data transfer speeds of up to 2000 Mbps – an ideal 2 port NIC for setting up dual homed, or multi-homed host configurations providing added security to corporate networks. The dual port Gigabit server adapter is compliant with the PCIe 2.0 standard and features support for Jumbo Frames and 802.1q VLAN tagging as well as Wake on LAN (WoL). The adapter includes an optional low-profile / half-height bracket that can be used for installation into a standard or small form-factor computer chassis. This dual Ethernet NIC card is backed by a StarTech.com 2-year warranty and free lifetime technical support.
