Storage advances and Ne over fabric

Traditional data storages Advantages: 서버에서 스토리지 독립 서비스 제공 편리함 용량 재할당 가능 FC/iSCSI SAN Disadvantages: Legacy 패브릭 (FC/iSCSI) Bandwidth 제약 높은 latency Advantages: 낮은 latency 높은 bandwidth Local SSD per server Disadvantages: 볼륨 크기는 각 SSD 용량으 로 제한 서버당 고정된 용량 SSD maintenance 어려움

Needs for fast drive - Ne SSDs become more common.. SATA/SAS interface s bandwidth is not enough for today s SSDs. Use of the fastest type of current SSDs, Ne is being increased.. Ne: PCI Express bus 를통해비휘발성 (non-volatile) 스토리지미디어에접속하기위한논리적디바이스인터페이스규격
