Network topology (tree, clos, fat-tree, thorus, etc)

This aspect restricts network traffic between components, servers, racks and between DC and the internet. Also, it sets DC's physical extendability properties, thus we need to think through how will be handled automated discovery and deployment of new nodes, which components are involved in such process and how the non-positive results of such cases are handled.
Obviously, we cannot fine-tune our setup for every topology type because it's not a standalone factor, so the set of variables in such analysis is large and too costly compared to the business-value of the outcome. But we can target the solution that covers topologies mostly used in target DC's with a sufficient degree of quality (metrics of service reliability and availability standards are something that cannot be purely theoretically calculated in the platform that is under heavy development and will rather be deduced during DC adoption process). Current The current assumption is that the most widely used topologies in the probable target DC group are fat-tree and various forms of clos. Based on that
