Pooled virtual machine collections. You can choose to deploy VDI through virtual machine pools. In this model, all users in the virtual machine pool share a single master image. The changes that each user makes during a session are stored in a transient virtual hard disk that’s discarded when the user logs off (though user profile changes are persisted). The main advantage of this model is having only a single image to manage, which reduces storage requirements and simplifies management, thereby reducing deployment costs. In Windows Server 2012, the entire model of deploying pooled virtual machine collection is transparent to the administrator. Single-image management and administration are natively supported, and the entire process is simplified for ease of deployment.

Personal virtual machine collections. Personal virtual machines are based on a master virtual machine. Windows Server 2012 automates the rollout process by copying the master image for each instance of the personal virtual machine. After the initial rollout is completed, you can maintain virtual machines as if they were physical machines and manage them by using WSUS and System Center Configuration Manager.

楼主你这是个纯Microsoft Windows Server 2012 Remote Desktop的问题啊,我建议到微软中文论坛里讨论由微软专家为你解答可能更合适些:

http://social.technet.microsoft.com/Forums/zh-cn/home

英文好的话可以到微软英文论坛讨论,里面的微软专家更多一些。

Windows Server 2012 中的 VDI 技术通过更简单的方式提供了丰富、完整保真的Windows 环境访问方式,这样的环境运行在数据中心内,几乎可运行于任何虚拟化设备上。通过Hyper-V与远程桌面服务,微软使用一种解决方案提供了三种灵活的VDI 部署选项:池化桌面、个人桌面,以及远程桌面会话(原来的终端服务)。更多信息:

你说的应该是池化桌面(Pooled Collection)和个人桌面(Personal Collection)吧,关于它们的区别和具体说明,请下载以下页面中最下边的白皮书,第10页有具体说明。

个人桌面(集合)和公共桌面(集合)就是指的Personal Virtual Desktop Collection和Pooled Virtual Desktop Collection吧。

Personal Virtual Desktop Collection: 管理员可和手动分配指定的虚拟桌面给指定的用户。通常用于那些需要特殊应用配置的用户。部署方法可以参考:Deploying Personal Virtual Desktops by Using Remote Desktop Web Access Step-by-Step Guide

Pooled Virtual Desktop Collection:  管理员部署虚拟桌面并随机分配给用户,用户登出桌面后可以回滚之前所有操作(可选)。一般用于那些使用大量相同应用和桌面设定的用户,比如呼叫中心。部署方法可以参考:Deploying Virtual Desktop Pools by Using Remote Desktop Web Access Step-by-Step Guide

感觉前者适合公司,每人一台自己的电脑;后者适合网吧,每次来都用不同的电脑。哈哈

“简而言之,个人桌面就是每个用户都可以拥有属于自己的虚拟机,并自行安装应用程序。对于公共桌面,用户与虚拟机不存在绑定的关系,用户也不应该在虚拟机中保存文件。

更详细的内容,请参考以下文档:

关于虚拟机池

关于个人虚拟机

这个是官网论坛的回复,请大家参考

谢谢Tim的帮助!

其实,最近我就在部署这两种桌面池,我主要是为选择设计类似于EMC的VSPEX的View的那种链接克隆桌面池,就开始研究这两种桌面池能更好的实施分级存储提高性能。

通过部署实际环境,我发现,只有公共桌面池才提供个人配置虚拟磁盘,这样我就可以将OS文件放在SSD上,个人配置文件放在SAS上,实现分级加速。

其实对于用户,这两种桌面,我自己感觉,在体验的时候是没有区别的,即都是自己的桌面,可以放自己的数据(公共桌面自己数据需要放在个人配置虚拟磁盘,否则有被还原的风险)。所以在存储侧设计的时候,会考虑那个类型能分开热点。大家觉得呢?

呵呵,我都部署过了,发现其实这两个桌面池类型所用存储都差不多(win7 64位,2个VM,占用28GB左右存储空间)

前者(个人集合)直接通过模板vm部署一个全新完整的vm(非差异磁盘)给一个用户使用。

后者(公共集合)也是通过模板vm部署一个特殊(差异磁盘)vm给一个用户使用。

个人集合:一个人使用一个完整的vm(由模板完全部署而来,系统虚拟磁盘为单个VHDX文件)

公共集合:多个人都使用一个特殊的vm(由模板作为母版,以差异磁盘部署而来,系统虚拟磁盘包括两部分“母版VHDX文件”+“差异磁盘VHDX文件”)

PS:差异磁盘是微软的虚拟磁盘的一种类型。即在差异磁盘建立后,所有上层操作都会被记录到该磁盘中,微软vm的快照就是利用差异磁盘来做的。
