Four RJ45 Gigabit Ethernet Ports

The W224-ST7230 provides four RJ45 Gigabit LAN ports on one PCI-E network expansion card.

This quad-port configuration is useful for computer systems that need several independent Ethernet connections without installing multiple separate network cards.

Typical use cases may include:

• Server network expansion

• Industrial computer networking

• Multi-network workstation configurations

• Virtualization hosts

• Network appliance integration

• System testing platforms

• Equipment requiring multiple LAN connections

Each port supports 10/100/1000Mbps transmission speeds, allowing the card to operate across Gigabit, Fast Ethernet, and standard Ethernet environments.

Dual JL82576EB Chipset Design

The W224-ST7230 uses two JL82576EB chipsets to support its four Gigabit Ethernet ports.

For B2B buyers and technical integrators, chipset architecture is an important purchasing parameter because it helps define the controller platform and supported networking functions.

The dual-controller design provides the hardware foundation for multi-port Ethernet connectivity along with features such as RSS, checksum offloading, VLAN support, Jumbo Frames, and virtualization-oriented device queues.

PCI Express x1 Interface with 5GT/s Bus Rate

The W224-ST7230 connects through a PCI Express x1 interface and complies with PCI-Express host interface specification v2.1.

The interface supports a bus rate of up to 5GT/s.

The card also complies with PCI Bus Power Management Interface Specification Revision 1.2.

Before ordering, system integrators should verify that the target motherboard provides a compatible PCI Express expansion slot and sufficient chassis space for installation.

10/100/1000Mbps Network Support

The W224-ST7230 supports three common Ethernet data rates.

Ethernet Type	Data Rate
Ethernet	10Mbps
Fast Ethernet	100Mbps
Gigabit Ethernet	1000Mbps

The card supports half-duplex operation at 10Mbps and 100Mbps and full-duplex operation across all supported speeds.

This allows the W224-ST7230 to integrate into both existing and Gigabit Ethernet network environments.

IEEE Network Standards and VLAN Support

The W224-ST7230 complies with multiple standard Ethernet specifications, including:

• IEEE 802.3

• IEEE 802.3u

• IEEE 802.3ab

• IEEE 802.3x

• IEEE 802.1Q

IEEE 802.3x Flow Control helps manage Ethernet traffic in supported full-duplex environments.

IEEE 802.1Q VLAN functionality allows compatible networks to separate traffic into logical network segments, which can be useful for servers, industrial systems, and virtualization environments that need multiple network zones.

Receive-Side Scaling for Multi-Core Systems

The W224-ST7230 supports Receive-Side Scaling, commonly referred to as RSS.

RSS allows incoming network traffic to be distributed across multiple processor cores in compatible systems, helping improve network packet processing efficiency.

For multi-core servers and workstations handling significant network traffic, RSS support can help reduce dependence on a single processor core.

Actual performance depends on the operating system, driver configuration, CPU architecture, and overall network environment.

IPv4 and IPv6 Protocol Support

The card supports both IPv4 and IPv6 networking protocols.

This provides flexibility for organizations operating current IPv4 networks while also supporting infrastructure designed around IPv6.

For B2B system integration projects, dual-protocol compatibility can simplify deployment across mixed network environments.

Jumbo Frames up to 9.5K

The W224-ST7230 supports Jumbo Frames of up to 9.5K.

Larger Ethernet frame sizes can help reduce protocol processing overhead when transferring larger volumes of data across a compatible Gigabit network.

For Jumbo Frames to operate correctly, the connected switches, operating system, network drivers, and other network devices must support compatible frame sizes.

TCP, UDP and IP Checksum Offloading

The W224-ST7230 supports UDP, TCP, and IP checksum offloading.

Checksum offloading allows supported network processing tasks to be handled by the network controller rather than relying entirely on the host CPU.

This feature can help reduce CPU processing requirements during network traffic handling, particularly in systems that manage multiple active network connections.

Virtualization and VMDq Support

Virtualization support is one of the important features of the W224-ST7230 PCI-E Expansion Card.

The card supports Virtual Machine Device Queues and Next Generation VMDq for up to eight virtual machines.

Virtualization Feature	Support
Virtual Machine Device Queues	Yes
Next Generation VMDq	Yes
Supported VMs	Up to 8
VMware ESXi Driver Support	Yes

VMDq helps organize network traffic for virtualized environments by providing hardware-assisted traffic handling for virtual machines.

This makes the W224-ST7230 suitable for compatible virtualization servers and lab environments that need multiple physical Gigabit ports.

Interrupt Throttling and CPU Optimization

The W224-ST7230 supports interrupt throttling control.

This function can limit the maximum interrupt rate generated by network traffic, helping reduce unnecessary CPU interruption and improve processor utilization in suitable workloads.

For systems processing multiple simultaneous Ethernet connections, this capability can provide more efficient use of host processing resources.

Management and Network Statistics

The card provides statistics for management and RMON.

These capabilities can be useful for network monitoring and system management applications where administrators need access to network traffic and interface statistics.

For server and network appliance projects, management-oriented functions can help simplify diagnostics and operational monitoring.

Operating System and Driver Support

The W224-ST7230 supports multiple operating systems and server environments.

Supported platforms include:

• FreeBSD

• Linux

• VMware ESXi

• Windows 7

• Windows Server 2008

• Windows 8

• Windows 8.1

• Windows Server 2012

• Windows Server 2016

• Windows 10

For deployment projects, customers should confirm the exact operating system version and driver requirements before large-volume purchasing.

Why Choose the W224-ST7230 PCI-E Expansion Card?

The W224-ST7230 is designed for B2B buyers who need more than basic Ethernet expansion.

Its combination of four RJ45 Gigabit ports, dual JL82576EB chipsets, PCIe x1 connectivity, RSS, VLAN, Jumbo Frames, checksum offloading, IPv4/IPv6 support, VMDq, and VMware ESXi compatibility makes it suitable for demanding network integration and virtualization applications.

For distributors, industrial computer suppliers, system integrators, and server solution providers, the card offers a clearly defined feature set for multi-port Gigabit Ethernet deployment.
