Abstract

The existing PC-based desktop environment is being changed to a server-based virtual desktop environment due to various advantages such as security, mobility, and upgrade cost reduction. In this paper, a virtual computing lab service system which is applicable to the existing computer lab is designed and implemented using both an open source-based cloud computing platform and hypervisor. In addition, a node power scheduler is proposed in order to reduce power consumption in a server farm. The experimental results show that the power scheduler reduces power consumption considerably over the server farm without the power scheduler.

기존의 PC 기반의 데스크탑 환경은 보안, 이동성, 업그레이드 비용 감소 등의 장점으로 인하여 서버 기반의 가상데스크탑 환경으로 바뀌고 있다. 본 논문에서는 오픈소스 기반의 클라우드 컴퓨팅 플랫폼과 하이퍼바이저를 이용하여 컴퓨터 실습실에 적용 가능한 가상 컴퓨팅 랩 서비스 시스템을 설계하고 구현하였다. 또한, 서버 팜에 있는 노드들의 전력 소모를 줄이기 위한 전원 스케줄러를 제안하였으며, 이 스케줄러 탑재 시 기존시스템에 비하여 전력 소모량을 대폭 줄일 수 있는 실험 결과를 제시하였다.
