StarTech ST1000SPEX43 4 Port PCI Express Gigabit Ethernet Card
Overview
The StarTech ST1000SPEX43 is a high-performance PCIe network interface card (NIC) designed to add four independent Gigabit Ethernet ports to a server or high-end workstation through a single PCI Express slot. This card is a critical hardware solution for IT professionals managing virtualization environments, firewalls, or software-defined networking (SDN) where multiple physical network segments are required for traffic isolation and load balancing.
Based on the reliable Realtek RTL8111H chipset, the card utilizes a PCIe 2.0 x4 interface (compatible with x4, x8, and x16 slots) to ensure sufficient bandwidth for all four ports operating at full duplex simultaneously. Each port supports 10/100/1000 Mbps auto-negotiation and is fully compatible with IEEE 802.3/u/ab standards. The independent nature of the ports allows for versatile configurations, such as link aggregation (teaming) for increased throughput or redundancy in mission-critical systems.
Designed for broad deployment, the ST1000SPEX43 includes both a standard-profile bracket and a low-profile/half-height bracket, making it compatible with both full-sized servers and small form factor (SFF) computers. It supports advanced features such as Jumbo Frames (up to 9K), Wake-on-LAN (WoL), and VLAN tagging (IEEE 802.1Q), providing the technical capabilities required for modern enterprise network management.
