Microsoft Hyper-V Server 2008 Releases
WOW!期待已久的 Microsoft Hyper-V Server 2008 终于正式发布。WOW!并且它还是一款免费产品。在阅读此篇日志的同时可以先访问 Microsoft Hyper-V Server 2008 从官方获取到简体中文版的 Hyper-V Server 。

Microsoft Hyper-V Server 2008(以下简称:Hyper-V Server) 可以简单的看作是一款虚拟化服务器,它是基于 Windows Server 2008 核心的,当你安装上之后,会发现它看起来更像是运行在 Server Core 上的 Hyper-V。当然这只是一种表面上的认识和第一印象!在未来的一段时间里,我会与大家一同深入地去了解和学习 Hyper-V Server。

下面的数据是 Hyper-V Server 2008 的系统需求:

To use Microsoft Hyper-V Server, you need 64-bit enabled hardware which supports hardware-assisted virtualization (Intel VT or AMD-V) technology:*

Processor
Minimum: An x64 processor with Hardware-assisted virtualization. This is available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization.
Hardware Data Execution Protection (DEP) must be available and be enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).
Recommended: 2 GHz or faster

Memory
Minimum: 1 GB RAM; Recommended: 2+ GB RAM
Maximum (64-bit systems): 32 GB

Available Disk Space
Minimum: 10 GB; Recommended: 40 GB or greater

Note: Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files

Network Adapters
Minimum: 1; Recommended: 2 or more

Drive
DVD-ROM drive

Display
Super-VGA (800 × 600) or higher-resolution monitor

Other
Keyboard and Microsoft Mouse or compatible pointing device
Internet access (fees may apply)
Active Directory highly recommended

Remote Management
Hyper-V Server requires a second system for remote management running:
Windows Server 2008 with the Hyper-V Manager MMC
Windows Vista SP1 with the Hyper-V Manager MMC
Microsoft System Center Virtual Machine Manager

Actual requirements will vary based on your system configuration and the number of virtual machines you choose to run. Processor performance is dependent upon not only the clock frequency of the processor, but also on the number of cores and the size of the processor cache. Disk space requirements for the system partition are approximate.

从系统需求来看 Hyper-V Server 在硬件需求方面并无大的变化,依然需要 CPU 支持 64位扩展(x64),并且要求支持硬件虚拟化技术(Intel VT or AMD-V),还需要支持硬件数据执行保护(HDEP)。

Microsoft Hyper-V Server 2008 Features and Benefits

Microsoft Hyper-V Server uses the same virtual machine model as Windows Server 2008 w/ Hyper-V enabled so there is no need to re-tool your management infrastructure.

        
  • VHD format: To move a virtual machine from Hyper-V Server to a Windows Server 2008 Hyper-V environment (or vice versa), simply export the virtual machine and import it on the other host using the standard management tools.
  •     
  • BitLocker support: Hyper-V Server can take advantage of BitLocker technology to encrypt a Hyper-V Server so that even if it is stolen and the hard disks are removed, the data is still safe because it’s encrypted. This is particularly useful for branch offices or environments where physical security is a concern.
  •     
  • Live Backup support: Hyper-V Server includes native support for Volume Shadow Services so that it can provide Live Backup of running virtual machines without downtime.
  •     
  • Flexible hardware support: Microsoft Hyper-V Server leverages the Windows Server driver model and is compatible with a wide variety of server hardware and driver support for newer peripherals such as 10 Gb/E.
  •     
  • Flexible Storage: Hyper-V Server offers flexible storage support, such as:    
              
    • Direct Attach Storage (DAS): SATA, eSATA, PATA, SAS, SCSI, USB, Firewire
    •         
    • Storage Area Networks (SANs): iSCSI, Fiber Channel, SAS
    •         
    • Network Attached Storage (NAS)
    •     
        
  •     
  • Virtual Machine Snapshots: Hyper-V Server fully supports virtual machine snapshots.
  •     
  • VSP/VSC/VMBUS: Both products fully leverage the driver enlightened architecture (VSP/VPC/VMBus) for high performance I/O. There is no conversion when moving virtual machines between Microsoft Hyper-V and Windows Server 2008 w/ Hyper-V.

Hyper-V Server (Parent Partition) provides:

        
  • Support for systems with up to 4 processors with 1, 2, or 4 cores
  •     
  • Support for systems with up to 32 GB of physical memory
  •     
  • Support for up to 128 virtual machines or as many will fit within 32 GB of memory (whichever comes first)

Hyper-V Server virtual machines provide:

        
  • 32-bit (x86) and 64-bit (x64) virtual machines
  •     
  • Up to 4 virtual processors per virtual machine
  •     
  • Up to 31 GB memory for all running virtual machines (1GB reserved for Hyper-V Server Parent Partition)
