Under the hood of the ST1000SPEXD4 PCI Express Dual-Port Gigabit Network Card lies a powerful solution for enhancing your network capabilities. This high-speed, reliable, and efficient network adapter card allows you to add two gigabit Ethernet ports to a client, server, or workstation through a single PCIe slot, making it a user-friendly and versatile choice for all your networking needs.Each port on this durable network card delivers 10/100/1000 Mbps capable Ethernet, fully compatible with IEEE 802.3/u/ab standards. This ensures seamless integration into any standard PCI Express-enabled system. With full-duplex flow control, this 2-port Ethernet card can achieve maximum data transfer speeds of up to 2000 Mbps, making it an ideal solution for setting up dual-homed or multihomed host configurations. This feature significantly enhances the security of corporate networks.The dual-port server adapter is compliant with the PCIe 2.0 standard and supports advanced features such as Jumbo Frames and 802.1q VLAN tagging. It also includes Wake on LAN (WoL) functionality for added convenience. The adapter comes with an optional low-profile/half-height bracket, making it suitable for installation into both standard and small form-factor computer chassis.This dual port gigabit PCI express server network adapter card is equipped with two 10/100/1000Mbps compatible RJ-45 Ethernet ports and supports up to 9K Jumbo Frame. It is compatible with PCI Express Base Specification 2.0 and is backward compatible with 1.0a/1.1. It is fully compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab and supports IEEE 802.1Q VLAN tagging, IEEE 802.1P Layer 2 Priority Encoding, and IEEE 802.3x Full Duplex Flow Control. The network card also supports Microsoft NDIS5 Checksum Offload (IP, TCP, UDP) and Large send Offload, Wake-on-LAN / Remote Wake-up support, and is configured with a standard profile bracket, with a low profile/half-height bracket included. It supports Pair Swap / Polarity / Skew Correction Advantage, providing critical networked systems with a redundant and independent Gigabit port.This network adapter card is ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs. It provides redundant connectivity to ensure an uninterrupted network connection and can be configured as a dual-homed proxy or gateway system for an added layer of security. It is specially designed for desktop PC clients, servers, and workstations with limited PCI Express slots available.
