VMware 推行一個遵循政策以維持準確的授權模式，每個實體 CPU 必須得到授權，並且
將計算出平均 12 個月消耗的 vRAM，而不是使用高標，如果 vRAM 的量超過了資源池
的量，將需要額外的授權，如果需要升級，客戶可以一個較高 vRAM 配額授權來升級所
有的 CPU。
以下，我們將檢視這些改變，以及它們將如何影響 vSphere 環境的每個部分。
CPU
限制
（CPU restrictions）
新的授權模式需要至少有一顆 CPU 在實體伺服器上。
vRAM
配額
（vRAM entitlements）
vRAM 是分配給虛擬機器的記憶體容量。舉例來說，如果您創立一個有 2GB 記憶
體的虛擬機器，即為 2GB 的 vRAM。無論單一 ESXi 伺服器的實體記憶體容量有多
少，我們有辦法超額配置 vRAM，只要從 vRAM 共享資源池的角度來看還是足夠
的話。
每台
VM
的
vRAM （vRAM per VM）
記憶體將會從 vRAM 授權資源池中取出，並且分配給虛擬機器。若最高分配給每個
虛擬機器的額度為 96GB，因此，如果一個虛擬機器分配了 128GB 的 vRAM，它將
只能自您的授權資源池取出 96GB。

vConverter 是 VMware 提供的一個免費的應用程式，它可以讓您輕鬆轉換實體伺服器為
虛擬伺服器，並將它們搬移到 VMware 系統上。有兩種方法可以辦到，在 ...
