We have heard a lot about the desktop version of Windows 7. The latest news is that Microsoft said that it will no longer release the Beta version of Windows 7 and the next upgrade The version will be the RC version closest to the final released product which also means that the final version is getting closer and closer to us. However according to Microsoft's enterprise-level operating system roadmap the server version of Windows 7 may be released later and will not be officially released until 2010.
Microsoft enterprise-level operating system roadmap
From the roadmap you can see the latest enterprise-level operating system which is the server version of Windows 7 and Instead of using its development code name 'Windows 7 Server' to name it it was named 'Windows Server 2008 R2' which means that the server version of Windows 7 is not like a major product upgrade from Win 2000 Server to Win 2003 but just An update of the existing Windows Server 2008 can be easily understood as an enhanced version of Win 2008.
At the Professional Developers Conference (PDC2008) at the end of October 2008 Microsoft showed the Pre-Beta version of Windows Server 2008 R2 for the first time but the version at that time was not perfect and did not provide a download trial. Until January 102009 Microsoft released the Windows Server 2008 R2 Beta version on the website providing users with a 30-day free download trial. The Beta version includes five versions: Standard Edition Enterprise Edition Data Center Edition Web Edition and Itanium Edition. The test version only provides English language.
Although there is no essential difference between Windows Server 2008 R2 and Win 2008 the basic features are of course the same but the R2 version incorporates some very attractive features:
X64 platform: Windows Server 2008 provides 32-bit and 64-bit versions but in R2 32-bit will be completely abandoned and only 64-bit versions will be available. In the server field 32-bit processors are already at sunset and will be completely replaced by 64-bit processors in a few years. Therefore Win 2008 R2 will be completely built on the X64 platform and it is also Microsoft's first operating system with only a 64-bit version.
Supports 256 logical processors: At the 2008 Microsoft Hardware Conference (WinHEC) Microsoft said when introducing Windows 7 features that Win 7 can support up to 256 logical processors. It also mentioned that Windows 7 Windows Server 2008 R2 with the same architecture can support up to 256 logical processors. Of course support for multiple logical processors makes more sense on the server side. The so-called logical processor refers to the number of physical processors multiplied by the number of cores and the number of threads. In other words Windows Server 2008 R2 can support 64 physical processors * 2 cores * 2 threads = 256 logical processors. Windows Server 2008 can support up to 64 logical processors.
Hyper-V 2.0 that supports Live Migration: In Windows Server 2008 R2 Microsoft’s server virtualization tool Hyper-v has been enhanced and Live Migration technology has been added. In a few milliseconds real-time migration between the physical host and the virtual machine can be realized without causing service or user link interruption. The data center has also achieved true virtualization largely separated from the management of software and hardware and all operations are completed within a single operating system framework. Hyper-V 2.0 virtual machines have enhanced support for logical processors and memory. The current Hyper-V can support 24 logical processors while each virtual machine in Hyper-V 2.0 can support 32 logical processors and up to 64GB Memory.
