很多朋友可能会问那么它与之前发布的Hyper-V有何不同呢？

1. Hyper-V Server 2008, 是100%免费的独立产品。
2. 100%裸机的hypervisor，只安装Hyper-V本身。不会包括任何与hypervisor无关的组件。
3. 与其他win2008集成版本的区别，如下图

以下是摘自微软虚拟团队(Microsoft Virtualization Team) blog对该产品特点的描述：

• Hyper-V Server 2008使用Windows hypervisor和其他组件，包括基本内核和驱动程序技术。微软Hyper-V Server 2008与Windows Server 2008共享核心组件。
• Hyper-V Server 2008包含了Windows Server 2008服务器内核(Server Core)部署选项的一个子集，它们有类似的界面和外观。如你所知，服务器内核具有DNS，DHCP，文件等角色。但Hyper-V Server 2008仅仅是虚拟化那一块。
• 由于Hyper-V Server 2008与Windows Server 2008共享核心组件，所以运行Hyper-V Server 2008不需要特殊的硬件驱动程序。
• Hyper-V Server 2008支持的最大虚拟机数量是128个（这当然还取决于硬件，内存及工作量的大小） 。此外，每个在虚拟机里的操作系统必须有一个有效的许可证。
• Hyper-V Server 2008支持所有Windows Server 2008 Hyper-V所支持的客户操作系统。具体的列表请看这里。
• Windows服务器许可证不包括Hyper-V Server 2008。客户端访问许可证(CALs)只需要运行在虚拟机上的操作系统。Hyper-V Server 2008本身无须客户端访问许可证。

Hyper-V Server 2008,软件的下载方法

微软Hyper-V Server 2008是一个单独的产品，将通过微软下载中心(Microsoft Download Center)免费发放。

该产品本身不需要客户端访问许可证(CALs)，但所有安装在Hyper-V Server 2008虚拟机上的操作系统需要有CAL。

微软Hyper-V Server 2008将提供下列语言：

• 英语 (EN-US)
• 德语 (DE-DE)
• 日语 (JA-JP)
• 法语 (FR-FR)
• 西班牙语 (ES-ES)
• 中国香港 (ZH-HK)
• 中国简体 (ZH-CN)
• 韩语 (KO-KR)
• 葡萄牙语 (PT-BR)
• 中国繁体 (ZH-TW)

Who has the most cost effective virtual infrastructure

The Task

There’s been some interesting hypervisor pricing comparisons circulating the Internet over the past two weeks that have caught my interest:

• VMware’s Mike Dipetrillo: ESX 3.5i for Free and the Impact on Hyper-V and the SMB
• Virtualization.info - Alessandro Perilli: VMware ESXi vs Microsoft Hyper-V: which one is better for SMBs?
• EvolveTechnologies - Dave Sobel: Is VMware Cheaper than Microsoft?

After reading with interest, I set out to conduct my own pricing evaluation, thinking that it couldn’t be too hard to get vendors to agree on a fair pricing comparison (insert joke here). To keep it simple, I decided to use a small branch office consisting of six Windows Server 2003 servers in the evaluation. I consider high availability a requirement in all production virtualization deployments and added virtual infrastructure management to the mix as well. To summarize, the solution requirements consisted of:

• Virtualizing six Windows Server 2003 servers on two 2-way physical hosts
• High availability failover support
• Centralized management of the virtual infrastructure

With the criteria set, I moved to evaluating vendor solutions with each vendor’s bottom line list price.

The Proposed Solutions

Table 1 below compares what I see as comparable solutions from VMware, Microsoft, Virtual Iron, and Citrix.

Table 1: Hypervisor price comparison (assumes Windows guest OS licensing is not required)

Citrix XenServer 4.1 does not include high availability, so the Status Avance OEM was used instead. Note that the pricing in Table 1 assumes that the branch office already has existing Windows Server 2003 licenses. If licensing is required, or if plans to upgrade branch office systems to Windows Server 2008 are in place, then the pricing comparison changes substantially. The Microsoft solution already includes licensing for 8 VMs, since Hyper-V is a part of the Windows Server 2008 OS. For the three other solutions, the cheapest way to go would be to purchase six Windows Server 2008 standard edition licenses for $995 each (total cost = $5,970 for six VMs). Downgrade rights would allow you to run Windows Server 2003 under the Windows Server 2008 license, and you would already be covered when it comes time to upgrade. Note that there’s no price difference with Windows Server 2008 and Windows Server 2003 Standard Edition licenses.

Table 2 shows vendor solution pricing with the Windows Server 2008 license included (added cost of $5,970).

Table 2: Hypervisor price comparison (assumes Windows guest OS licensing is required)

As you can see, OS licensing cost is a significant factor. With the cost of OS licensing, the Microsoft Hyper-V solution changes from the most expensive to the least expensive. Also, it should be noted that both Table 1 and Table 2 reflect vendor list pricing. Since vendor discounts vary, the resulting paid price for any of the above solutions could be thousands less. Still, the list pricing comparison should give you a good idea of where each vendor stands.

The Fruit of My Labor

I had to use a minimal configuration in order to make the vendor comparisons as close as possible. VMware eloquently stated that for an apples-to-apples comparison with Hyper-V, I should include Systems Center Operations Manger and System Center Configuration Manager in the Microsoft price. However, while Virtual Center does a few things that Virtual Machine Manager doesn’t do, System Center Configuration Manger and Operations Manager can do much more than Virtual Center. So to balance the comparison, I would have to add System Center Configuration Manger and Operations Manager to the price of each solution, making the addition a wash. The same happened when backup was added to the equation. Citrix and Stratus would also argue that their solution includes local storage mirroring support, so purchasing shared network storage is not required and could represent considerable savings. VMware also noted that their price includes a year of Gold Support, and that similar support on competitive offerings could raise the price as much as 20%. Since I cannot buy a VMware product without support, I’m keeping the support cost in my comparison because it does represent the minimum price. In addition, Virtual Iron’s competitors have been quick to note that Virtual Iron does not have a similar supporting vendor ecosystem, which is a decision making factor you won’t find on a product data sheet.

So I’m sure vendors will still argue along the lines of apples-to-apples, but I counter that I am comparing apples-to-apples while agreeing that some may be tastier than others. You may see some of the solutions as granny smith apples and others as red delicious apples. On the outside, they’re all apples, but on the inside the experience is unique to each one.

Fruitless? Fruitful? I welcome your feedback.
