    Sammanfattning : More and more people are using the internet for data processing, transfer, and storage. With it comes a higher demand for computational power from data servers. Unsurprisingly, the data center industry is becoming an increasingly large industry that is important for people’s daily lives. LÄS MER

  3. 2. Energy Modelling for Data CenterInfrastructure

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Huang Zhang; [2017]
    Nyckelord :;

    Sammanfattning : In this thesis work, a comprehensive static data center model with raised floor design is developed with improvements based on previous master thesis work. Enhancement work focuses on IT virtualization technology, a general server model, more detailed chiller system and mechanical system, novel modeling methodology for power devices (PDU and UPS).

  5. 4. LQR and MPC control of a simulated data center

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Erik Berglund; [2017]
    Nyckelord :;

    Sammanfattning : One of the largest contributions to a data center’s power usage is its cooling system. To decrease the energy usage of the cooling system, an automatic control scheme that adapts the capacity of the cooling units is needed. In this master thesis, a Simulink model of a data center is developed, along with several LQR and one MPC controller. LÄS MER
