Raid
帶有 RAID1+0 的 HP P410 上的磁碟性能非常慢
我有 HP Microserver N54L,直到最近我使用集成軟體 raid 沒有問題。我的 RAID 陣列有 2x WD Black 和 2x WD Red(非專業)磁碟。我還在主機板上直接安裝了 SSD(沒關係,只是為了弄清楚所有事實)。
我購買了帶有 256MB 記憶體的 HP P410,並帶有一個 Battery Back Write Cache 模組。
我正在使用 esxi 5.1,並且我有一個 Windows 虛擬機。在這台 Windows 機器上,我的讀取速度很差(最高只有 40-60 MB/s),寫入速度還可以(大約 100MB/s),但仍然比我使用集成 raid 時慢。
例如,這是將一個大文件從 raid 複製到 ssd http://img.hihi.si/Upload/vYbD.png :(
這是我的 RAID 控制器和陣列資訊

有什麼想法該怎麼做?我需要提供更多資訊嗎?
我在HP ML350 G6 p410i raid控制器中遇到一個情況,首先我在Raid 5中建構了一個三盤,速度比SATA III磁碟快,大約600-800M的讀寫速度,這對我來說很神奇,但是當我調整為4磁碟raid 5,它讀取速度更快但寫入變得像一個通常的磁碟很慢,最後我發現問題: 我偶爾點擊讀/寫緩衝區設置,它是100%讀取和0%在寫作中,這就是問題所在,只有 50% 到 50% 或 60% 到 40%,它又快了。配置在 HP Stmart Storage Administrator 中
