Lenovo X540 10Gb Dual Port Adapter

The Lenovo X540Product is a 10Gb Ethernet network adapter with two RJ-45 ports. It is designed for IBM System x servers including the x3550 M4, x3650 M4 and x3650 M4 HD. The card suits administrators who need 10GBASE-T connectivity over existing copper cabling. It provides dual-port 10Gb throughput for high-I/O workloads in enterprise environments.

PCIe 2.0 x8 Low Profile Form Factor

The adapter uses a PCI Express 2.0 x8 host interface in a low-profile card form factor. It fits into compatible server slots without requiring additional SFP+ modules or fiber cabling. The RJ-45 ports work with existing 1000BASE-T infrastructure, simplifying the transition to 10Gb Ethernet. This design frees up space in dense chassis such as the iDataPlex dx360 M4.

Sustained Line-Rate 10Gbps Performance

The Intel X540 controller delivers full line-rate 10Gbps performance under sustained load for high-I/O intensive applications. It maintains consistent throughput across both ports during extended operation rather than short bursts. The adapter showcases enterprise-grade 10GbE networking features for data center reliability. It supports demanding workloads that require continuous high-bandwidth data transfer.
