On the basis of the previous release, Windows Server 2008 R2 continues to promote applications in such areas as virtualization, System Management resiliency, network access, and information security, with a number of features that need to match windows 7. The advent of R2 is not just about expanding the applicability of server 2008, but also about how to accelerate the popularity of Windows 7 in the enterprise environment.
The next version of the Windows Server system is only a 64-bit version, and important new features include:hyper-v to join the dynamic migration function as an improvement to the rapid migration function in the initial release. Hyper-V will calculate the migration time in milliseconds. This is a strength of hyper-V functionality compared to VMware's ESX or other hypervisor. and strengthen the PowerShell management directives for each server role. Other features include:
Featured 1:hyper-v 2.0─ virtualization features and availability are more complete
Hyper-V 2.0 supports live migration dynamic transfer and enables more Linux operating systems to be installed on VMS.
Six months after the launch of Windows Server 2008, Microsoft launched the virtualization platform Hyper-V 1.0, built on Windows Server 2008, which has basic virtualization capabilities but is relatively weak compared to other virtualization platform features, For example, the lack of dynamic transfer capabilities makes it impossible to transfer VMs to other entity servers without stopping the virtual host (VM). This feature is supported by the Hyper-V 2.0 on Windows Server 2008 R2, making this virtualization platform a significant step in usability.
Hyper-V 2.0 new features
Support Live Migration Dynamic migration
Can dynamically adjust capacity on virtual disks
Have VM memory dynamic configuration function
Able to boot on the entity host with a virtual image file
VM-supported operating systems add Red Hat Linux
The main control (host) supports up to 32 processor logical cores
Improve VM Computing Efficiency
Featured 2:active Directory Administrative Center, offline join network domain, AD resource Recovery cartridge ─AD Enhanced management interface and deployment flexibility
Active Directory (AD) has always been a pivotal server role in the Windows Server operating system, and has been enhanced in Windows Server 2008 R2. For example, with a new ad management interface, at the same time can use the PowerShell command operation, but also to allow the computer to join the domain offline, and there is an ad resource recycling station, increase AD membership flexibility.
Featured 3:windows PowerShell 2.0 and Server core─server Core mode support. NET
The R2 improves Server core because it does not support the. NET Framework and does not use PowerShell's shortcomings, and now, in the Server Core, where the command operation is the main claim, it can be paired with PowerShell to make the operation more efficient.
