Data Center Tier Classification The Tier classifications were created to consistently describe the site-level

Data Center Tier Classification The Tier classifications were created to consistently describe the site-level infrastructure required to sustain data center operations, not the characteristics of individual systems or sub-systems. The requirements were established by the Uptime Institute, Inc. and are necessarily and intentionally very broad to allow innovation in achieving the desired level of site infrastructure performance, or uptime. The individual Tiers represent categories of site infrastructure topology that address increasingly sophisticated operating concepts, leading to increased site infrastructure availability. 4

Data Centers Tier I: Basic Site Infrastructure • • • Non-Redundant Capacity Components and

Data Centers Tier I: Basic Site Infrastructure • • • Non-Redundant Capacity Components and Distribution paths. Any Capacity Component or Distribution Path failure will impact the computer systems. Planned work will require most or all of the systems to be shutdown. Tier II: Redundant Capacity Components Site Infrastructure • • • Redundant Capacity Components, but single Non-Redundant Distribution Paths serving the site’s computer equipment. Redundant UPS modules and engine generators are required. A distribution path failure will cause the computer equipment to shut down. Tier III: Concurrently Maintainable Site Infrastructure • • Redundant capacity components and multiple distribution paths serving the site’s computer equipment. Generally, only one distribution path serves the computer equipment at any time. Each and every capacity component and element of the distribution paths can be removed from service on a planned basis without causing any of the computer equipment to be shut down. Tier IV: Fault Tolerant Site Infrastructure • • • Redundant capacity systems and multiple distribution paths simultaneously serving the site’s computer equipment The site is not susceptible to disruption of service from a single unplanned worse-case event. Infrastructure maintenance may be performed by using redundant capacity components and distribution paths to safely work on the remaining equipment. 5

Electrical Capacity for Evanston Data Center Hosting Rooms 171 and 172 • What is

Electrical Capacity for Evanston Data Center Hosting Rooms 171 and 172 • What is the protected load capacity? Safe Electrical Draw is 240 k. VA • What is today’s consumed load? Today’s Draw is 210 k. VA A power reduction plan is underway to shed load and bring the total draw down to 195 k. VA for these two rooms. Thus providing 45 k. VA of unused safe draw to utilize. Small Research Center Room 173 • What is the protected load capacity? Safe Electrical Draw is 128 k. VA • What is today’s consumed load? Today’s Draw is 20 k. VA 8

Electrical Capacity for Chicago Data Center Hosting Rooms 232 and 234 • • What is the protected load capacity? Safe Electrical Draw is 300 k. VA What is today’s consumed load? Today’s Draw is 300 k. VA A power co-generation project to bring additional power into this location has been cancelled by Facilities Management is recommending the purchase of a larger diesel generator. 9
