Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Energy efficiency of a cloud computing infrastructure is an increasingly important issue for IT operators of data centers.
Increasing energy costs of data centers and environmental awareness have motivated research into energy efficient and power proportional cloud computing infrastructure.
Research on energy efficient and power proportional cloud computing infrastructure is divided mainly into two categories: power aware storage architectures, and energy efficient processing architectures.
Energy efficient storage solutions mainly focus on the use of solid state disk and on keeping storage in idle or off state.
On the other hand efficient processing solutions can be divided into using on low-power processors, energy aware caching, and dynamic resource provisioning.

This Thesis aims to investigate and evaluate applications of efficient storage and processing techniques.
These techniques, their applicability and limitations are analysed, evaluated, and compared with each other.

This Thesis also analyses the behaviour of the Solr search engine on solid state disk and conventional hard disk.
Solr search engine is a fairly popular enterprise search platform.
Thus, the effect of the underlying storage technology for Solr engine running on top of solid state and hard disks is compared and analysed with respect to energy efficiency and cost concerns.
Advantages and disadvantages of different storage systems for Solr search engine are discussed.
