ÈÄÁöÂê RX200 S8 - ssd raid 1 ¼Óµµ°¡ ³Ê¹« ³ª»Þ´Ï´Ù

후지쯔 RX200 S8은 LSI 컨트롤러를 쓰는데

ssd 2개를 연결해서 만든 raid 1의 성능이 너무 나쁘게 나옵니다.

config의 문제는 아닌 것 같은데, 원인이 뭘까요?


6개의 sas를 raid 10으로 걸었더니 435MB/s가 나왔습니다.

WriteBack, ReadAhead, strip size : 64kb

[root@kcolo122-199 ~]# sync && dd if=/dev/zero of=/dd_test bs=4k count=1000000 && sync
1000000+0 records in
1000000+0 records out
4096000000 bytes (4.1 GB) copied, 9.41727 s, 435 MB/s


2개의 micron ssd (500GB)를 1로 걸었더니 38MB/s가 나왔습니다.

WriteBack, ReadAhead, strip size : 64kb (WriteThrough로 바꿔도 성능 개선은 미미하구요)
