For existing data centres with available power, cooling, and space capacity, the decision is often an obvious one, but when a data centre is at or near full capacity, a decision must be made as to where the additional IT equipment is going to be accommodated. According to authors Brown and Wendy Torell, there are three fundamental approaches to meeting the new capacity requirement:
Upgrade Physical Infrastructure
Depending on the capabilities of an existing data centre, upgrading the facility may be sufficient to meet new IT requirements. The level of disruption, cost, and capacity gain depends largely on the scope of the upgrade project, which may include anything from implementing simple air flow management practices like adding blanking panels, to adding a high-density pod to increase power, cooling, and/or rack capacity in a low-density data centre. An “at a view” table summarises the types of upgrades that are assessed and contrasted to outsourcing in the paper.
Build a New Data Centre
Increasing levels of standardisation, modularity, and data centre infrastructure management (http://www.schneider-
For example, building a data centre with scalable, pre-assembled, and integrated facility power and cooling modules may provide TCO savings up to 30% compared to traditional, built-out data centre power and cooling infrastructure. When evaluating the costs of building vs. outsourcing data centre physical infrastructure, prefabricated, modular data centre (http://www.schneider-
Move to Co-location
Co-location has been of growing interest due primarily to the fast deployment capability, and the providers’ core expertise in operating data centres which leads to a secure, highly available space with economies of scale that can help keep costs competitive. Outsourcing to the Public Cloud is a further extension of this, where not only the physical infrastructure is outsourced, but also the software (SaaS), the IT infrastructure (IaaS), and/or the platform (PaaS).
White Paper 171: Considerations for Owning versus Outsourcing Data Center Physical Infrastructure
The decision between the three approaches is based on financial savings, sensitivity to cash flow, and other key strategic factors. The former two categories, cost and cash flow, are quantitative, while the third, strategic factors, consists of common business preferences and constraints that affect the decision qualitatively. Some of the strategic factors may eliminate certain alternatives altogether, while other factors can heavily influence the decision, depending on the business objectives and priorities of the decision maker(s).
The 10-year TCO may favour upgrading or building over outsourcing, however, White Paper 171 demonstrates that the economics could be overwhelmed by a business’ sensitivity to cash flow, cash cross-over point, deployment timeframe, data centre life expectancy, regulatory requirements, and other strategic factors. The new paper, which is available for free download, discusses how to assess these key factors to help make a sound decision.
