Megaraid ? esxi?なぜか遅い

原因が全くつかめない、ディスク交換したから？

とりあえずMegaraidの設定を疑う
Megaraidの設定でポリシー

Disk Cache Policy：Disable
Read Policy ：Read Ahead
IO Policy：Direct IO
Write Policy：Write Through
で全く性能出ず・・・・・おかしい


次に
Disk Cache Policy：Enable
Read Policy ：Read Ahead
IO Policy：Direct IO
Write Policy：Write Through
で全く性能出ず・・・・・おかしい

息継ぎ、息継ぎ

次に

Disk Cache Policy：Enable
Read Policy ：Read Ahead
IO Policy：Cache I/O：
Write Policy：Write Through
で全く性能出ず・・・・・おかしい
おお・・・読み込み戻ってきた！！！！！！！！！！！！！

が、もう一回すると

元の木阿弥

結局現在は
Disk Cache Policy：Enable
Read Policy ：Read Ahead
IO Policy：Direct IO
Write Policy：Write Through

全体的に遅い

なぜ。


HDDはエラーをはいていないようなのだが
