[Oracle Cloud Free Tier] block volume (블럭볼륨) 활용하기

[Oracle Cloud Free Tier] block volume (블럭볼륨) 활용하기

 

 

이번에 오라클프리티어를 다음과 같이 꾸몄다.

1. Arm 3cpu 18ram   (메인활용)

2. Arm 1cpu 6ram    (테스트활용)

3. block volume 100G    (메인에 붙일 예정)

 

 

 

몇가지 설정법

- auto tune 추천

 

 

 

- paravirtualized 추천   (iscsi 보다 성능이 좋다고 한다)

 

 

 

 

- fdisk 로 확인
