Abstract

Recently, Usage of multimedia server is rapidly increased with expansion of internet that real-time displaying service for multimedia data, MPEG and etc. For these multimedia real-time applications, it is necessary to use a disk array as a storage system. For providing requested service to much more clients at the same time in a multimedia data storage server, considerable varied strategies in a several parts. But especially it is important feature to various parameters for disk array such as relation of striping block size as a system environment and characteristics of video data. In this paper, we implemented real environment of multimedia server which provides MPEG-1 files and evaluated the suitable storage system architectures by applying synthetically generated workloads in the various parameters for disk array.

최근 MPEG등의 멀티미디어 데이터를 실시간으로 재생 서비스하는 멀티미디어 서버의 사용이 인터넷의 발전과 더불어 급격히 증가되고 있다. 이러한 멀티미디어 실시간 응용에서 저장시스템으로서 디스크 배열의 사용은 필수적이다. 멀티미디어 데이터 저장 서버에서 동시에 보다 많은 고객들에게 요청되어지는 서비스를 제공하기 위해서는 여러 분야에서의 다양한 정책들이 고려될 수 있다. 그러나, 특히 시스템의 환경과 비디오 데이터의 특성에 따른 스트라이핑 블록 크기의 관계와 같은 디스크 배열을 위한 다양한 특성변수들은 성능을 좌우하는 중요한 요인이다. 본 논문에서는 MPEG-1 파일을 제공하는 실제 멀티미디어 서버의 환경을 구축하고, 디스크배열을 위한 다양한 특성변수들을 여러 가지로 발생되어지는 작업부하에 적용해 봄으로써 최적의 저장시스템 구조를 평가하였다.
