SPECI-2 an Open-Source Framework for Predictive Simulation of Cloud-Scale Data-Centres

The authors introduce Version 2 of SPECI (Simulation Program for Elastic Computing Infrastructure), a system for predictive simulation modelling of ultra-largescale Data-Centers (DCs), i.e. warehouse-sized facilities containing hundreds of thousands of servers, as used to provide cloud computing services. The move toward cloud computing is driving the construction of ever bigger DCs. For example, Microsoft's latest cloud-computing DC in Chicago has an estimated budget of US$500m and capacity for 224,000 blade-servers (Miller, 2009). The scale of such facilities means that the designers of these facilities have to work with data from development and testing set-ups that are often several orders of magnitude smaller than the final product.
