問題:
硬體Firewall/switch ACL/Windows firewall相關設定都查過
telnet vcenter-ip 443也有通
但使用powercli就是怎樣也連不上
後來google才發現是powercli那台設備有設定proxy，而proxy設備因為firewall policy沒開連不到vCenter
解決方式:
關閉proxy或是設定vcenter IP不使用proxy

環境:
Dell R610 300G sas x4 (RAID5), 200G sata ssd x 2 (RAID1)
裝了2顆SSD但是在vCenter上無法正常辨識為SSD，因此無法啟用host cache，必須利用下面的選項將SSD datastore標記為SSD

host cache是write or read cache?(待確認)
從Swapping to Host Cache看起來是VM swap file的write cache
