SAS vs NVMe 아키텍처비교

SERIALACCESS

하나의 CHANNEL하나의 QUEUE

Serial 아키텍처는 한 개의 HBA에 많은 Device가연결될 때의 문제점을해결

SAS는 느린 CPU 및 HDD 환경에서 사용하기에는충분한 아키텍처

ACCESS

최근의 CPU는 더욱 병렬화 되고, SSD는 더 높은 IOPS를 지원

Memory기반의 아키텍처는 Multiple Device에 병렬로Access하도록 허용

기존의 SAS 아키텍처는 느린 CPU 및 HDD환경에서는 적합하였으나, 더욱 높은 성능과 병렬화를 지원하고 있는 최근의 CPU 및 SSD를위한 새로운 아키텍처가 필요합니다.
