This paper compares one megaWatt of IT capacity deployed in two different ways. Using Uptime Institutes True TCO (total cost of ownership) Calculator (Koomey,©2007, Uptime Institute), Elliptical Mobile Solutions (EMS) has contrasted a traditional or legacy datacenter facility to a micro data center-based build (including a metal shell building). The purpose of this comparison is to show the savings potential afforded by a micro-container-based infrastructure. The recent Uptime Institute study reveals that the TCO of a Tier 3 or Tier 4 (referring to Uptime Institutes Tier Classification System for determining a data center facilitys availability and resiliency) datacenter is $25,000/ft2. The Institute has determined that each 42U rack of Tier 4 equipment requires 100ft2of raised floor including support equipment allocated per rack. The micro data center has 20ft2 allocated for floor space/ergonomic considerations despite its actual physical foot print of 14ft2 with all physical support equipment is onboard.
