Lenovo ThinkSystem Broadcom 5719 1GbE RJ45 4-Port PCIe Ethernet Adapter

Overview

The Lenovo 7ZT7A00484 is a four-port Gigabit Ethernet adapter designed to enhance network connectivity for Lenovo ThinkSystem and ThinkAgile servers. It provides four RJ45 copper-based Ethernet ports through a single PCI Express 2.0 x4 interface, allowing administrators to add multiple network connections without using multiple PCIe slots. Powered by the Broadcom BCM5719 controller, this adapter supports jumbo frames up to 9600 bytes and includes features that optimize network traffic and reduce CPU load, making it suitable for environments that require reliable and efficient data transfer.

Key features

• Four Gigabit Ethernet ports consolidated into one PCIe 2.0 x4 slot to maximize server expansion options
• Broadcom BCM5719 network processor ensures stable and consistent network performance under heavy traffic
• Support for jumbo frames up to 9600 bytes improves throughput during large file transfers and backups
• Receive Side Scaling balances CPU usage across multiple cores for efficient processing of network packets
• TCP/UDP checksum offload reduces host CPU overhead, freeing resources for other tasks
• IEEE 802.1Q VLAN tagging and IEEE 802.3x flow control maintain organized and smooth network traffic flow
• Built-in PXE boot and iSCSI boot support enable network-based startup and deployment for streamlined IT management
• Includes both low-profile and full-height brackets for flexible installation in various server chassis
