Intel IT operates 17 data centers with 56 data center modules. These data centers are home to over 305,600 servers that underpin the computing needs of 3 more than 110,800 employees . Intel’s business is becoming increasingly data-driven, relying on machine learning, artificial intelligence, big data analytics, and automation. As data explodes, we are experiencing a 30 to 40 percent in demand for network capacity every year. Intel IT is dedicated to supporting the needs of Intel’s critical business functions—Design, Office, Manufacturing, and Enterprise (DOME). But we also are committed to operating our data centers as efficiently as possible. To meet these two goals, we have engaged in a multiyear evolution of our data center strategy—including the makeup of our data center networks. Over the last 10 years, we have steadily upgraded our network ports from 1 gigabit per second (Gbps) to 10 Gbps to 40 Gbps. We are now migrating to multiple-100 Gbps inter-switch links to keep up with traffic growth (see Table 1). But “fast” is not the only thing we are concerned about. We also look at return on investment (ROI) to help ensure we are implementing the most Read the full Increase Network Bandwidth with Optics.

Intel IT is using Intel® Silicon Photonics to affordably increase network bandwidth in Intel's data centers.

Intel’s demand for network bandwidth grows 30 to 40 percent a year. As a result, a key component of Intel IT’s data center strategy is network innovation. Intel IT is increasing deployment of 100 gigabits per second (Gbps) connectivity, using Intel® Silicon Photonics.

When Intel IT compared Intel® Silicon Photonics to conventional optics-based technologies, they found that it provides the following advantages:

  • Uses less power (only 3.5 watts)
  • Is less expensive

Intel IT standardized on the CWDM4 MSA QSFP28 model because it can span up to 2 kilometers on SMF. This model can also operate in a wide range of temperatures (0° to 70° Celsius) at low power (3.5 watts), which was important for variety of data center deployments.

Over the last 18 months, Intel IT has deployed more than 8,000 100 GbE ports across Intel and 3,000 Intel® Silicon Photonics Optical Transceiver. The deployment of Intel® Silicon Photonics has enabled us to meet the growth in demand for network bandwidth without significantly increasing costs.

Intel IT's adoption of Intel® Silicon Photonics helps improve network utilization, reduces costs per port, and enhances overall data center efficiency. Intel IT has reduced the costs associated with all network components (physical cabling, active switch equipment design, and optics). This has enabled Intel IT to lower the overall cost of transitioning to 100 Gbps. What’s more, Intel IT is poised to break new ground with even faster network technology - they are ready to meet the data explosion head-on and satisfy Intel’s demand for data processing for the foreseeable future.
