Analysis and Implementation of Data Center Virtualization at the ICT Center Fkip UNS

The need for information system at the Faculty of Teacher Training and Education, Sebelas Maret University, Surakarta, is increasing. Yet, the improvement of the information system has not been in proportion to the server availability. A solution is therefore required as to deal with the limitation in hardware resources at the aforementioned institution. In this research, the virtualization of data center at the Faculty of Teacher Training and Education, Sebelas Maret university, Surakarta, was proposed. The virtualization method used in this research was hypervisor virtualization with the software of Proxmox VE. The web server performance was tested, and the web server performance of the virtual environment was compared to that of the physical environment. In addition, the calculation of the server cost and the network cost in the virtual environment used currently was also analyzed. The result of the analysis on the web server performance shows that the web server within the virtual environment can serve users as similarly as the web server within the physical environment prior to the application of virtualization. The result of the test shows the decrease in the web server performance, but it is still acceptable because the average percentage of the decrease in the performance is 7.8 % out of the total percentage of the web server performance within the physical environment. In addition, the ICT Center of the Faculty of Teacher Training and Education, Sebelas Maret University can save the operating costs for the server and the network up to 48.11 % and 35.134 % respectively when employing the virtualization infrastructure at the data center.
