The Intel Ethernet Converged Network Adapter X550 hosts Intel's advanced Ethernet silicon, the Intel Ethernet Controller X550, a low-cost single-chip 10GBASE-T solution for server platforms.
With 10GBASE-T, migration to 10 GbE is dramatically simplified with backward compatibility for your existing GbE network infrastructure. Install an X550 adapter into a server and the auto-negotiation between 1 GbE and 10 GbE provides the necessary backwards compatibility that most customers require for a smooth transition and easy migration to 10 GbE. When time and budget allows, 10GBASE-T switches can be added any time to experience the full benefits of 10 GbE. 10GBASE-T uses the copper twisted-pair cables. It is all you know and love about 1000BASE-T. 10GBASE-T is an easy and versatile 10 GbE interface that can be deployed anywhere in your data centre. Its flexible reach supports the advanced network architectures including Top of Rack (ToR), Middle of Row (MoR), and End of Row (EoR).
The Intel Ethernet Converged Network Adapter X550 is low-cost way to deploy 10 GbE in your data centre. The Intel X550 uses low-cost Cat6 and Cat6a cabling. Chances are this cabling already exists in the data centre. A way for Intel to reduce cost and power is to integrate components into a single-chip solution. Why is integration important? First, integration translates to lower power. This means no active heat sink and reduces the per-port power consumption. Second, integration also means a lower cost per port, because two separate components are not needed. When cabling is accounted for, cost efficiencies realised from a single part mean 10GBASE-T is low-cost media to deploy. With lower cost and power, 10GBASE-T is ideal for broad deployment. 10GBASE-T is a solution for every rack and tower server in the data centre.
Converging data and storage onto one fabric eliminates the need for multiple adapters and cables per server. Furthermore, 10 GbE provides the bandwidth to converge these multiple fabrics into a single wire. A key capability that makes all this possible is traffic class separation provided by Data Center Bridging (DCB). DCB provides a collection of standards for additional QoS functionality such as lossless delivery, congestion notification, priority-based flow control, and priority groups. This enables the CNA X550 family to provide a one-wire solution with virtual pipes for the different classes of traffic.
Virtualisation changes server resource deployment and management by running multiple applications and operating systems on a single physical server. With Intel Virtualisation Technology for connectivity, the CNA X550 family delivers outstanding I/O performance and QoS in virtualisation data centres and cloud environments. I/O visualisation advances network connectivity used in servers to more efficient models by providing FPP, multiple Tx/Rx queues, Tx queue rate-limiting, and on-controller QoS functionality that is useful for both virtual and non-virtual server deployments.
