Adaptec
關於 Adaptec Raid-Controller 上的寫入記憶體設置和寫入記憶體狀態的混淆
由於性能問題，我想驗證是否確實為 Adaptec ASR71605 Raid-Controller 啟用了寫入記憶體。
write-cache setting=enabled我可以看到和之間的不匹配write-cache status=off，我想知道記憶體是否真的啟用了。當顯式啟用記憶體時
arcconf setcache 1 LOGICALDRIVE 1 wb，狀態不會改變。請參閱下面的 arcconf 輸出：

根據 Adaptec 的支持，寫入記憶體在韌體更新和下一次重新啟動之間的時間內不起作用。
實際上，已經進行了韌體更新而無需重新啟動，
arcconf getversion如果該命令列出了一個Staged Version數字，則可以看到這一點。
