Intel Ethernet Converged Network Adapters X540 host Intel's latest Ethernet silicon, the Intel Ethernet Controller X540, which is used by many OEMs as a single chip solution for LAN on Motherboard (LOM) to deliver 10 Gigabit Ethernet (10GbE) on the latest server platforms. With the new Intel X540 Controller, the MAC and the PHY are integrated into a single-chip solution. The Intel X540 family of products works with existing networks today, including legacy Gigabit Ethernet (GbE) switches and Cat 6A cabling. Install the Intel X540 adapter into a server and the auto-negotiation between 1GbE and 10GbE provides the necessary backwards compatibility that most customers require for a smooth transition and easy migration to 10GbE. When time and budget allow, 10GBASE-T switches can be added anytime to experience the full benefits of 10GbE. 10GBASE-T uses familiar copper twisted pair cables and is the easiest and most versatile 10GbE for deployment anywhere in the data center. Its flexible reach from 1 meter to 100 meters supports the latest network architectures including Top of Rack (ToR), Middle of Row (MoR), and End of Row (EoR).
