安裝 megacli
#cd /usr/ports/sysutils/linux-megacli/ && make install clean
會出現須自行至 LSI 下載檔案到 /usr/ports/distfiles,下載完後若沒 load linux kernel module 記得先 kldload linux 後再 make (忘記沒 load 的話編到哪裡會出錯)。編完後照著說明編輯 loader.conf、sysctl.conf、fstab 等檔案。megacli 指令可參考 Managing PERC 6 with MegaCli under Solaris 10 或是 MegaCLI cheat sheet。Raid 5 效能測試

因為卡上有 256MB 的 cache 加上有裝電池可以開啟 write back,所以 128MB 的測試根本是爆表的快,不過 4GB 的測試結果也不錯。從 win7 上的 SSD 透過 samba (Gb網路) 寫入 2GB 檔案速度大都維持在 90~100MB/s。本來還想測 rebuild 時間,但剛裝好後的 background initialization 大約 10 分鐘才跑 1%,看到要這麼久就放棄了。後來查到可以透過 megacli –adpsetprop 來設定 RebuildRate 和 BgiRate,馬上將它設定成 100% (預設是 30%),反正遇到硬碟壞掉一定是停止檔案服務全速重建 raid。
