Description
ITM 472: Information Technology Service Management
Getting Started
A data center is a place to house computer servers that software applications run on. You can have internal data centers or use servers that are provided by a vendor like Amazon Web Services.
Besides the security aspect, think about all the components of a data center – the building, the raised floor, the fire-suppression system above the computers, the racks, the server components, networking components and wiring, cables under the floor, power units, air conditioning units, and room for people to walk around in front and behind the cabinets. Within the same room or in another quieter room you might see monitoring stations to watch over what is going on in the data center. Below is a picture and website showing the inside of a data center. Infrastructure as a Service (IaaS) allows an IT manager to build up their data center remotely through a third-party vendor to supply the facility and hardware and networking needed. People decide to do this to have other people manage it or to have the flexibility to add more infrastructure easily for a fee. (Image credit: Christina Morillo (Pexels.com); used by permission.)

Indiana University’s “Big Red 200” data center went online in January 2020. It is a “supercomputer designed to support scientific and medical research, and advanced research in artificial intelligence, machine learning, and data analytics.” How fast is it? According to their publicity materials, if everyone who lives in the state of Indiana performed one calculation per second 24 hours a day, 7 days a week, 365 days a year, it would take them 28 years to perform the same number of calculations that Big Red 200 can do in just one second!
The facility itself is about 3/4 underground (in a berm) and designed to withstand an F5 tornado. Additionally, they also had 2 diesel-powered backup generators the size of a small apartment (with a 3rd coming soon) to supply the electrical power to run the facility in the event of a power loss from the main electric supply, and this backup generator kicks in after a fly-wheel based backup system fails. So if the entire town or campus lost power, the flywheel setup would take over within 30 seconds, serving as a UPI to deliver backup power while the diesel generators fired up (20 minutes), and the system could continue uninterrupted for days.

So yes, literally…the entire university and much of the town could be wiped out by a massive tornado, but the computer infrastructure would keep running and they could restore full computing operations within a half-hour of a serious outage and run for 4-5 days until external power and utilities infrastructure could be restored.

Data centers produce a lot of heat and require significant mitigation to cool them. Here the director of the center shows a prospective student the liquid cooling system within the Big Red 200 supercomputer (blue is cool incoming liquid, red is outgoing hot liquid, all delivered to within micrometers of the chips doing the processing. Other server racks had a ventilation in-flow/outflow setup at each rack (with fans and AC units) which kept the area around each rack cooled, and the floors themselves (which housed the vast majority of the wiring between units) also have a built-in water cooling system.

The OmniSOC at Indiana University’s data center is a Secure Operations Center (SOC), a cybersecurity system shared by 5 universities. Its aim is to help members reduce the time from first detection of a security threat to campus mitigation. The computing power of these racks is incredible: Each cluster is capable of handling about a billion events of data per day and has 100 Tb of SSD-backed storage per cluster.
