2.2 選擇虛擬機器資料儲存位置
問題
您需要最佳實務指引以將您的虛擬機器置放在特定的儲存類型。
解決方案
在本訣竅中，我們針對在部分儲存類型上置放虛擬機器的目標，整理了一些業界標準與
最佳實務。
討論
在我們開始之前，值得一提的是，當您將虛擬機器置放在儲存空間時有著許多的影響因
素。隨著業界新技術的發展，出現了一種標準稱為
儲存分層
（
Storage Tiering
），它能讓
SAN 或儲存陣列自動化在兩種不同的磁碟之間搬移資料。舉例來說，您可能在 SAN 上
混合了 15,000RPM 與 7200RPM 的磁碟，分層的主要目標是要讓每種在磁碟上的各種類
型資料，都可以利用適合的速度提供使用。SAN 上的軟體會自動的搬移不同的磁碟類型
之間的工作負載，一般是以區塊層級運作，重要的是要注意每個 SAN 供應商的技術會
稍有差異。
在此我們以虛擬機器的角度，檢視在不同層中涵蓋的部分。
