Before moving onto DCI technologies, let's look at two clustering technologies that can be used to remove the physical loop caused by the Spanning Tree Protocol (STP). All rights reserved. All data centers are essentially buildings that provides space, power and cooling for network infrastructure. In this blog, I'll look at different options for DCI and how well they fulfill our design requirements for a DCI. Data sets coming into or leaving a data center can be very large—from hundreds of Gigabits to Terabits. Our low-profile building design allows a high level of security within the data center. The multi-tier data center model is dominated by HTTP-based applications in a multi-tier approach. 4.2.3 Modular Data Center in Shipping Containers. Interconnection networks are composed of following three basic components − 1. The design of interconnection networks for distributed-memory multiprocessors and networks-on-chips is well established (see, for example, , which is the standard text, particularly as regards distributed-memory multiprocessors, and , where the focus is on networks-on-chips) and a thriving area of research. But you may not be able to avoid the complexity of a L2 DCI, either because of poorly designed application or virtualized workloads. Gartner does not endorse any vendor, product or service depicted in its research publications, and does not advise technology users to select only those vendors with the highest ratings or other designation. IDC explains how creating value, growth, and competitive advantage through new offerings, new business models and relationships requires 3rd Platform IT and interconnection-oriented architectures. VXLAN does not do any policing of BUM traffic. Capacity: Data centers store and deliver the data applications require. If all hosts are known, then there is no need to flood frames.
