一、虚拟化涉及的架构

  硬件方面的结构如下:

wKioL1OJ2AnyqMB0AADoRSM0Idg079.jpg


注意:在禁用超线程时,硬件线程(hardware thread)等于“物理核”的数量;启用超线程时,硬件线程等于2倍的物理核的数量。 


  虚拟化的架构如下:

二、虚拟化授权概述

  通过“每核”模式购买许可时,必须为虚拟机中的每一个虚拟核(virtual core)购买独立的许可,而且每一台虚拟机最少要购买4个“每核”许可。

  出于许可的目的,一个虚拟核映射到一个硬件线程。当为单个的虚拟机授权时,不考虑核的系数。

  注意:当 SQL Server 2014 标准版运行在一个“每核”模式授权的虚拟环境中,为每个独立的虚拟机授权是唯一有效的许可方式。


SQL Server 2012 试算:

(1)某台虚拟机用了2个虚拟核,运行SQL Server 2012 标准版。需要购买4个“每核”许可。因为每台虚拟机最少需要4个“每核”许可。

(2)某台虚拟机用了4个虚拟核,运行SQL Server 2012 标准版。需要购买4个“每核”许可。

(3)某台虚拟机用了6个虚拟核,运行SQL Server 2012 标准版。需要购买6个“每核”许可。
