Change History Changes in the May 5 update: Added SR645 and SR665 to the server support table - Server support section Added OS support for ThinkSystem Broadcom 5719 1GbE RJ45 4-port OCP Ethernet Adapter, 4XC7A08235 - Operating system support section Introduction The Broadcom NetXtreme Gigabit Ethernet Adapters are a family of high performance PCIe and OCP adapters. The adapters are available with either two ports or four ports and are supported on ThinkSystem and System x servers. Figure 1 shows the Broadcom NetXtreme I Quad Port GbE Adapter. Figure 1. Broadcom NetXtreme I Quad Port GbE Adapter Did you know The NetXtreme Quad Port Ethernet Adapter is an ideal way to implement a virtualization solution using your existing Gigabit Ethernet network. With four copper-based Gigabit ports on a single PCI Express 2.0 x4 interface, the adapter provides the density and capacity you need to support large numbers of virtualized systems on one server.
