Data Centers What is a datacenter? Page 129, “ a data center is a place where you keep machines that are a shared resource” Other terms that basically mean the same thing Server room Machine room Server closet Many things that make a data center more than just another room where computers run

Data Centers To get the benefits on a good server room, you don’t need to “build-it-yourself” $100 - $400 per square foot to build Rent space from a hosting company This is known as a “co-location Facility” Rent ‘services’ from a hosting company such as RackSpace.com or peer1.com where they provide you the CPU, memory, disk (I/O) and networking. Remember from last week, you don’t care about the physical server, just the service running on it. If the service is up, what’s what matters.

Location Where is your data center going to be located? How many do you need? Large multi-national corporations may have many with one acting as a primary and others as a backup May run data centers concurrently as to balance load and provide immediate fail-over Smaller companies or educational institutions may have many, one for each college, or a few for the entire university May be placed ‘strategically’ around the university or around the area (CNY) as to minimize expense. Even the best data centers with redundant power, cooling, etc. can fall victim to a contactor with a backhoe or excavating equipment.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
