This three-day course covers data center design background, historical and current challenges, today's requirements and drivers, and Juniper Networks recommended solutions. It presents designs to meet those requirements and overcome the identified challenges. The course provides an overview of various network technologies used in data center network designs, including Fibre Channel over Ethernet (FCoE), Internet Small Computer System Interface (iSCSI), MPLS, various types of virtual private networks (VPNs), Layer 2 technologies, and virtualization. To enhance the learning experience, the theoretical parts of the lecture materials are complemented with hands-on design case studies. The case studies provide further enhancements to student learning experiences, enabling students to apply principles of data center design best practices to specific examples.
