sas hdd °ü·Ã

안녕하세요.

ProLiant DL380 Gen10 서버에 P408i-a Raid Controller를 사용하고 있습니다.

Disk fio가 너무 떨어져서 sas disk를 low level format을 해 보려고 합니다.


Raid를 모두 풀고,

sda, sdb, .... 이런 형태로 구성이 가능한지요?

아니면 별도의 hdd dock이 필요할까요?


이 형태로 개별 low level format을 진행하려고 합니다.

회사에 있는 HP 시리즈는 모두 동일합니다.

모두 동일하게 SSD가 장착되어 있습니다.

일단 상당한 진전이 있었습니다.

SPP Update는 영향을 주지 않았습니다.

Physical Drive Write Cache Enable 이후 속도가 빨라졌습니다.
