This article mainly shows you "how to choose hardware for Windows Server 2008 R2". It is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn this article "how to choose hardware for Windows Server 2008 R2".

Compared to software, hardware has always played a relatively minor role. After all, software really determines who can make remarkable achievements in the IT world. However, choosing the right hardware may be the most critical factor when deploying new technologies. Take Microsoft Windows Server 2008 R2 as an example, which is used in most local area and world wide web. If the hardware selection does not match the requirements of the administrator, there will be a problem, it may be that the application runs slowly, or it may be over budget, and more seriously, it may lead to the failure of this commercial application.

Choosing the right hardware for Windows Server 2008 R2 is certainly not as simple as verifying each option as on the server purchase order. Before you try to narrow down your choices, there are several key steps and important considerations to consider carefully. * * step to determine the version of Windows Server 2008 R2 (there are at least five versions here) and which server roles will be used (there are dozens of server roles here).

Windows Server 2008 R2 has specific requirements for CPU. First of all, it requires 64-bit processors, and when R2 comes out, Windows no longer supports 32-bit processors. This may sound hard to understand, but most processors in the market today support 64-bit operating systems. This means that almost all new server hardware can meet this minimum requirement. Of course, as the name implies, the minimum requirement is only the minimum! Without increasing the burden on the network, you need to choose more hardware to meet your current and future needs, and all of these minimum requirements need to be kept within budget.

Of course, Microsoft has made a list of recommended configurations for each version of Windows Server 2008 R2.

Windows Server 2008 R2 basic

Windows Server 2008 R2 basic is an entry-level version for small businesses. It is one of all versions, with some advanced features missing, such as only a simplified active directory and no Hyper-V virtualization capabilities. In addition, the basic version also limits existing features, such as limiting the number of concurrent remote desktop service connections to 50, and using up to one processor and 8 gigabytes of memory. So, with this version, you don't need to buy multiple processors and more than 8 gigabytes of memory, in other words, entry-level servers will use the basic version of Windows Sever 2008 R2.

Windows Server 2008 R2 Standard Edition

The standard version is also an entry-level server system. This version only supports 64-bit operating systems, and in terms of hardware, the standard version supports up to 4GB memory and four processors.

Windows Server 2008 is primarily targeted at the SMB market, providing * * domain, Web, DNS, remote access, printing, file management and application services. However, the standard version does not support clustering, so it cannot be used for deployment in a fault-tolerant environment, data center, or other larger enterprise environment. But the standard version helps to reduce the requirement for hardware. And multiprocessor support can come in handy if the standard version is deployed in a multitasking environment. In addition, if you want to add more features to the server for the future, the upgrade is also very convenient. Windows Server R2 Standard Edition supports direct upgrades from Windows Server 2008, Windows 2000 Server, and Windows Server 2003 Standard Edition.

Windows Server 2008 R2 Enterprise Edition

Windows Server 2008 R2 Enterprise Edition provides more powerful features and scalability than Standard Edition, including support for up to 16 nodes of cluster and active directory federated services (ADFS). The core operating system also supports more advanced features, such as up to 8 processors and up to 2TB memory.

For the enterprise version, the hardware considerations have become a bit complicated. IT managers need to consider how many users the server will support, how to plan a cluster, and how many other services and roles will need to be deployed (such as SQL server, Sharepoint, and so on). Each increase in services and roles consumes resources and storage space.

Other features, such as Hyper-V virtual services, firewall services, terminal services, remote desktop, failover, and synchronization services, each of which adds to the burden on the server. Windows Server 2000, Windows 2000 Advanced Server, Windows Server 2003 Standard Edition, and Windows Server 2003 Enterprise Edition can all be upgraded directly to Windows Server 2008 R2 Enterprise Edition.

Windows Server 2008 R2 data Center Edition

Data Center Edition is a * end product in the Windows Server 2008 R2 product family, mainly aimed at business-critical enterprises that require stability and high availability. Windows Server 2008 R2 data Center Edition supports up to 2TB memory and 8 to 64 processors. You can upgrade directly from the data center version of Windows Server 2008, Windows 2000 and 2003 to the data center version of Windows Server 2008 R2.

For the data center version, IT managers will find themselves in a world of rack-based blade servers, SAN arrays, and other high-end rack devices. Here, technical support, like all features and functions, plays an equally important role in turning hardware devices into a more manageable and highly fault-tolerant environment.

Windows Web Server 2008 R2

Windows Web Server R2 2008 is essentially a version dedicated to providing Web services. It includes IIS 7.0and related services such as simple Mail transfer Protocol (SMTP) and Telnet. It can support up to 4 processors, but only 32GB is supported in memory. Compared with other entry-level products, Windows Web Server R2 2008 lacks many features, such as clustering, BitLocker-driven encryption, multipath IAccord O, Windows Internet naming Service (WINS), removable storage management, and SAN management.

Web Server Edition can run on low-end server devices or with minimal hardware cost, and it can deploy Windows servers in a cheaper form. Because there is no traditional upgradeable path, the Web server version is easy to install without much consideration for hardware configuration. But the cost is that, as demand increases, you may have to port it to a different Web server platform to ensure hardware matching.

So far, we have introduced the choice of hardware from the basic aspects, but it is much more than that. Perhaps the problem is the expectation of the network, that is, its growth in the future, and whether there are plans to upgrade in the future.

Other important factors include whether you want to deploy clusters / blades or SAN, as well as future network conditions. For many people, the easiest way is to discuss network needs and aspirations with the server provider, and then choose a hardware plan, including the provider's technical support, simple upgrades, and pre-installed Windows Server. As a result, the scale is left to the engineers and the deployment is left to the IT staff.

The main selection decision depends on whether you are looking to deploy a cluster / blade or SAN, as well as expected activities on the network. For many people, the easiest way is to discuss network requirements and the need for server manufacturers and then pick a bundled product that provides vendor-supported hardware that is easy to upgrade and pre-installed in Windows Server. In doing so, the standards are left to the engineers, while the deployment is left to the IT staff.
