Eight Advantages of Windows Server 2008 R2

Windows Server 2008 R2 is the next generation version of Microsoft's server operating system. Its features and features are based on existing Windows Server 2008, and have been further enhanced and improved. The system development codenamed Windows Server 7, which is equivalent to the server version of Windows 7, is the same. Win Server 2008 R2 will better support virtual machine migration, as Microsoft said, using Hyper-V to narrow the gap in VMware architecture. In addition to server virtualization, there is also a significant increase in IIS, networking, and terminal services. Below, this article will be discussed from several major aspects of the system:

Windows Server 2008 provides 32-bit and 64-bit versions respectively, but in R2 will completely discard 32-bit, only 64-bit version. In the server field, 32-bit processors are already in the future, and 64-bit processors will be the trend of the future. This is also Microsoft's first operating system with only a 64-bit version.

At the 2008 Microsoft Hardware Conference (WinHEC), Microsoft introduced Windows 7 features that Win 7 can support up to 256 logical processors, and Windows Server 2008 with the same architecture as Windows 7. R2 can also support up to 256 logical processors. 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.

In Windows Server 2008 R2, Microsoft's server virtualization tool Hyper-v has been enhanced with the addition of Live Migration technology, which can be implemented between physical hosts and virtual machines in a matter of milliseconds. Live migration without disruption to service or user links. The data center also achieves true virtualization, largely from the management of software and hardware, all in a single operating system framework. The Hyper-V 2.0 virtual machine is enhanced with logical processor and memory support. Currently 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.

PowerShell is an object-based shell officially released by Microsoft in the fourth quarter of 2006. PowerShell 2.0 has also been released in beta and user technology previews. It will be available in Windows Server 2008 R2. It was fully integrated into this software when it was officially released. Win 2008 R2 includes a new set of server management interfaces, all built on top of PowerShell 2.0. It adds 240 cmdlets command sets, and the new PowerShell graphical user interface adds development capabilities, making it easier for users to create their own command line. Moreover, PowerShell will be able to install to the Windows server kernel.

Power Management Enhancements: Windows Server 2008 R2 includes a "Core Parking" feature that evaluates the processing workload of multi-core servers and can in some cases terminate the sending of new work to these cores. Then, when the kernel is idle, it can put the server to sleep and reduce the overall power consumption of the server.

The IIS version in Windows Server 2008 R2 is 7.0, which is more powerful with the latest PowerShell 2.0 support, including updates to failover clusters and some recent popular IIS extensions (such as WebDAV and Administration Pack). And it also supports more development technologies such as SilverLight and PHP.

Direct Access and Branch Cache: The Direct Access DA feature in Windows Server 2008 R2 allows users to access files, data, or applications on the corporate network from any network location without having to go through traditional Virtual enterprise network VPN. Direct access reduces the operational complexity of end users and ensures the security of remote access. The latter is to reduce the bandwidth used by users for LANs based on HTTP and SMB communication, to improve branch office productivity. When a remote branch user accesses data on the Windows Server 2008 R2 system at headquarters, the data can be stored on the branch office. Therefore, if another user wants to access the same data, there is no need to connect to the headquarters. The cost of resources, these two major functions require the operating system with the front and rear end to maximize the effectiveness.

This is a new feature in Windows Server 2008 R2 that migrates to a new system when DHCP fails. DHCP failover allows administrators to plan and deploy a highly resilient DHCP environment through a Windows DHCP server. This feature can also be used as a platform for building Windows IP management solutions, providing administrators with a comprehensive experience in managing their DHCP infrastructure.

Windows Server 2008 R2 helps implement Server Core by adding IIS and .Net support, which in turn allows PowerShell to take advantage of these improvements. Hyper-V 2.0 and its live migration will help to further integrate Windows server integration, and the introduction of Terminal Services will show the perfection of remote desktop services. Of course, not everyone can benefit from IIS 7.5, and that doesn't mean everyone needs to eagerly upgrade the functional level of their Active Directory domain and other functions such as Branch Cache and direct access—and also need to upgrade to Windows. 7. Overall, the operating system will likely be welcomed by organizations with large virtual machines, large Web businesses, and many other virtual machines.
