Enhanced from the current highly-praised version, PLANET ENW-9803 version 3 10GBASE-T PCI Express Server Adapter adopts Marvell AQtion LAN controller solution. It comes with PCI Express rev. 3.0 specification x4 interface and other advanced features as follows: Smaller and compact in design 10M/100M/1G/2.5G/5G/10GBASE-T RJ45 Multi-gigabit network solution Supports iSCSI/FCoE/PXE/Other boot Low profile bracket    10 Gigabit Performance yet Low Cost and Low Power The ENW-9803 comes with one 10GBASE-T RJ45 interface and low-profile PCI Express form factor. As the new ENW-9803 uses Marvell AQtion LAN controller solution, it is a low-powered, high performance model that supports IEEE 802.az Energy Efficient Ethernet (EEE). The new ENW-9803 NIC adapter reference design supports auto-negotiation for allowing the NBASE-T solution to optimally select the best and flexible speed like 10 Gigabit Ethernet (10GbE), 5 Gigabit Ethernet (5GbE), 2.5 Gigabit Ethernet (2.5GbE), 1Gigabit Ethernet (GbE) or 100 Megabit Ethernet (100MbE) over Cat 5e/Cat 6/Cat 6A or better cabling. It is designed to address system application requirements by offering the best cost, 10Gbps high performance, low power consumption and better-quality solution in the 10Gbps network market today.   Cost-effective and Ideal 10G Copper NIC Adapter Compared with 10G adapter with CX4 and SFP+ interface, PLANET 10GBASE-T PCI-E adapter is the best choice in that the ENW-9803 10GBASE-T can reach up to 100 meters over Cat.6a or Cat.7 RJ45 cable, whereas the CX4 and SFP+ interface only can work with fixed speed rate. However, the ENW-9803 10G copper NIC adapter can adjust and work with the speed rate of 100M/1G/2.5G/5G. The CX4 interface can only extend up to 15 meters in distance. The cost is too high for having an extra SFP+ interface for the SFP+ transceiver. However, with the ENW-9803, customers only spend on Cat.6a or Cat.7 cable as the ENW-9803 is bundled with RJ45 connector, thus costing less than the SFP+ transceiver.  10G Spec. Interface Media Maximum Distance Total Ownership Cost 10GBASE-T RJ45 Cat.6a/Cat.7 UTP cable 100 meters (328 ft) Low 10GBASE-CX4 CX4 Copper 15 meters (49 ft) Medium 10GBASE-SR SFP+ Multi-mode fiber cord 300 meters (984 ft) High 10GBASE-LR SFP+ Single mode fiber cord 10 km (32808 ft) High   10GbE Device Designed for Low-power, Low-cost and Single-port Applications The ENW-9803 is an optimized 10GbE device designed for low-power, low-cost and single-port applications required in application servers, high-end workstations and personal computers. This makes it ideal for enabling 1GbE to migrate to 10GbE for bandwidth-intensive workstation applications and low-end to mid-range network appliances. With the innovative PCI Express Bus Architecture, it offers increased bandwidth, reliability and additional functionality compared with standard GbE network cards. The performance of throughput at rates up to 20Gbps is unbelievable, thus eliminating the bottleneck that exists with the current Gigabit network. PLANET ENW-9803 is designed to connect your servers and workstations, guaranteeing extremely high throughput and excellent signal quality.    Standard 802.1Q VLAN Support Moreover, the ENW-9803 supports IEEE 802.1Q VLAN which allows it to operate in a flexible and secure network environment. With 16K jumbo frame ability and IEEE 802.3 flow control support, it further optimizes throughput and wire-speed packet transfer performance without risk of packet loss. The high data throughput of the device makes it ideal for most 10 Gigabit Ethernet environments.   Multiple OS Support The ENW-9803 operates completely well with most of the popular and latest operating systems including Microsoft Windows Server, Linux and VMware, enabling simple integration into network designs. There is no need of any modification to the server’s operating system or any special software required for the ENW-9803 to be integrated into the system.
