NGS(Next Generation Storage) 시스템은 전형적인 분산파일 시스템 구조의 병목 현상을 제거하고 입출력 대역폭을 늘려 성능을 최대화 하기 위한 차세대 저장시스템으로 기존의 저장시스템과는 달리 DRAM을 기반으로 스토리지를 구성하고 있다. NGS 시스템의 대용량 지원 및 기업 내부에서의 활용을 위해서는 SAN 기반에서 활용할 수 있도록 설계되어야 하며, SAN 환경에서 성능 향상을 위한 연구가 필요하다. 본 논문에서는 NGS 시스템에 대한 성능평가 및 분산 환경에서 NGS 를 활용하기 위한 성능평가도구 개발을 기술한다. 성능 도구의 활용은 전형적인 전체 시스템 아키텍처 내의 병목 현상을 제거하고 입출력 대역폭을 늘려 성능을 최대화 할 수 있어야 한다.
