Windows Server 2012 R2: Everything You Need to Know

Hello Dev, if you’re looking for an in-depth guide to Windows Server 2012 R2, you’ve come to the right place. In this article, we’ll cover everything you need to know about this powerful operating system, from its features and benefits to its system requirements and installation process.

What is Windows Server 2012 R2?

Windows Server 2012 R2 is the successor to Windows Server 2012, a server operating system released by Microsoft in 2012. This new version brings many improvements and new features, including enhanced virtualization capabilities, better storage management, and improved networking performance.

If you’re looking to deploy a new server infrastructure, or upgrade your existing one, Windows Server 2012 R2 is definitely worth considering. Let’s dive into some of its most important features and benefits.

Feature #1: Enhanced Virtualization Capabilities

Virtualization is one of the key features of Windows Server 2012 R2, and it has been greatly improved compared to its predecessor. With Hyper-V, the built-in hypervisor, you can create and manage virtual machines with ease, and take advantage of features such as live migration and dynamic memory allocation.

In addition, you can now implement virtualization at the storage level, thanks to Storage Spaces. This allows you to create virtual storage pools by combining multiple physical drives, and then allocate storage to your virtual machines as needed.

Overall, the enhanced virtualization capabilities of Windows Server 2012 R2 make it a great choice for organizations that need to run multiple workloads on a single physical server.

Feature #2: Better Storage Management

In addition to virtualization, Windows Server 2012 R2 also brings improvements to storage management. With Storage Spaces, as mentioned above, you can create virtual storage pools and allocate storage to your virtual machines. This can help you save on hardware costs, by allowing you to use commodity hardware to create your storage infrastructure.

Another new feature is Storage Quality of Service (QoS), which allows you to manage the storage performance of your virtual machines. With QoS, you can specify the minimum and maximum IOPS for a virtual disk, ensuring that it always has the necessary performance to run efficiently.

Finally, there’s Deduplication, a feature that allows you to save space by eliminating duplicate files. This can be especially useful for organizations that deal with large amounts of data, such as backup files or virtual hard disks.

Feature #3: Improved Networking Performance

Networking is another area where Windows Server 2012 R2 has seen improvements. With the new NIC Teaming feature, you can combine multiple network adapters into a single logical interface, providing better performance and availability. You can also create a Virtual Switch to connect your virtual machines to your physical network, and take advantage of advanced networking features such as network isolation and bandwidth management.

Another new feature is IP Address Management (IPAM), which allows you to manage your IP addresses and DHCP/DNS servers from a single console. This can help you save time and reduce the risk of errors when configuring your network.

System Requirements

Before you can install Windows Server 2012 R2, you’ll need to make sure your hardware meets the minimum system requirements. Here’s what you’ll need:
