EMC NAS : LAN 기반이지 FC 기반이 아니다. 디렉토리 구조를 최대한 평평하게 가져 가야 한다. 시간이 지날수록 파일이나 디렉토리 구조가 쌓이기 때문에 성능 저하가 생긴다. 파일 읽고 쓰는 과정에서 실제 데이타를 쓰고 읽는데 쓰는 리소스는 30%이고 70%는 LOOKUP하는데 쓰인다.SAN : FC 기반이고 네트웍 인프라(예 : 샌 스위치)가 있어야 한다. 디바이스를 독점한다.물리적인 개념 Fibre 논리적인 개념 FABLIC(네트웍의 subnet 개념)FCIP(IP에 FC 방식을 얹은것)iFCP(routing이 가능한 개념)FCOE(FC Over Ethernet, CNA(FC(8GB),EE(10GB)(Enhanced Ethernet))CNAEFD(Enterprise Flash Drive)http://.. 더보기
