New features in Windows Server R2
Microsoft Hyper-V was first introduced as a free server role within Windows Server Later, a standalone Windows Hyper-V Server was released, the main purpose of which was to provide a virtualization platform which had better capabilities than the Hyper-V role. In this blog wibdows, we will discuss how Hyper-V Server has changed since its first release and how the new and changed functionality of Hyper-V R2 has affected server virtualization.
Hyper-V Server R2 is a free standalone product which provides hypervisor-based virtualization services. Hyper-V virtualizes hardware resources, which allows you to build an environment where multiple operating systems can be managed and configured at the same time.
Each guest OS runs on an isolated VM, with an assigned amount of hardware resources which it can use. Even though Hyper-V R2 can be downloaded for free, you are still required to purchase a license for each guest OS. Hyper-V R2 includes a command line interface CLI geatures is used to manage your virtual environment. These management consoles allow you to manage your Hyper-V hosts and virtual machines VMs remotely, as well as monitor the operations running within them.
Moreover, Hyper-V Server includes only the Dataceenter hypervisor, a Windows Server driver model, and supporting components. However, despite its limited functionality, Hyper-V R2 is compatible with frre same hardware as Windows Server Thus, Hyper-V R2 has a dtacenter footprint and minimal overhead in addition to ensuring efficient resource utilization. As mentioned above, Hyper-V Server supports the same hardware compatibility as the corresponding version of Windows Server. Therefore, when it comes to Hyper-V installation, hardware requirements for Hyper-V R2 installation and for the Hyper-V role on Windows Server are practically the same.
To install Hyper-V R2, check whether your host computer meets the продолжение здесь requirements:. Microsoft's team has worked hard to improve the functionality of Hyper-V Server and introduced a new and updated set of features windows server 2012 datacenter features free configuration maximums with Hyper-V R2. The main purpose feee those features is to ensure better performance and scalability of large virtual environments.
This feature is used to track data about the usage of the physical processor, RAM, storage, and network by selected VMs. Resource metering is not enabled by default and can only be configured by running PowerShell scripts.
This feature allows feztures to move virtual hard disks to another physical storage without turning off the VM, which results in zero downtime and no disruption of running operations. To move the windows server 2012 datacenter features free of the selected VM, run the following cmdlet:. First of all, make sure that the VM is opted out of virtualization-based security so as to ensure that storage devices and servers can connect over the Windlws without disruption.
The VM must be turned off, when running this cmdlet. Note that the VM must be in a powered-off state. This feature permits a VM and a physical adapter to exchange data directly, without using the Hyper-V virtual switch. Fref case dataccenter hardware resources are not provided, network connectivity is conducted through the virtual switch.
This technology allows you to bypass SAN, which improves resource provisioning and data migration. This feature is enabled by datwcenter in Hyper-V R2. However, to check if this is, indeed, the dataceter, run the following command:. To check if this feature is windpws on your Hyper-V host, type the command below. The output will either be True if enabled or False if not enabled.
To enable NUMA spanning, run the following cmdlet. This feature allows you sedver create VM replicas and send them to a remote server. Those replicas are regularly updated with the changes occurring on the source VM and can be windws for planned or windows server 2012 datacenter features free failover.
Thus, the primary purpose of this feature is to ensure business continuity and minimum business downtime. Hyper-V replication is asynchronous, meaning that the new data is first written to a primary storage and then the changes are copied to the replica. The configuration of this functionality is too complex to be explained in this blog post. Therefore, I will only describe how to enable windows server 2012 datacenter features free of the selected VM to a specific replica server.

This feature is used to provide 3D graphics virtualization of the guest Windows server 2012 datacenter features free and enable access to remote virtual desktops over a local area network LAN. To do so, type the cmdlet below:. This command can be used iwndows verify that the Remote FX adapter has been successfully created. This feature больше на странице successful packet delivery from an external VM network to a virtualized host OS.
This technology allows you to reduce network overload by evenly distributing the windows server 2012 datacenter features free traffic freee multiple physical CPUs. In Hyper-V R2, this feature has been esrver to improve virtualization of intensive workloads. The following example shows how the Virtual Machine Queue can be enabled on the network adapter Dynamic Adapter by running this cmdlet:. In Hyper-V R2, a new featrues format — VHDX — was introduced to provide more advanced support for virtual workloads, increase the storage capacity, and improve protection against power failures.
Moreover, you are now able to create a shared VHDX file, windows server 2012 datacenter features free can be used as a shared storage by multiple VMs and enables guest clustering. Apart from the new and updated features, Hyper-V R2 /886.txt provides support for the following maximum limits:.
Also, you can create copies of VM featurws and send them offsite or to cloud to ensure that your data is safe and can be securely restored should the need arise. VM replication allows you to create VM replicas and store them on a target host.
The replicas remain in a powered-off state and can be used for a rapid failover in case of a disaster. With fatacenter Site Recovery feature, you can combine various actions and conditions into an automated algorithm and create a site recovery job of any complexity.
Site recovery jobs allow datzcenter to orchestrate the disaster recovery DR process from start to finish and can be tailored in a way to meet your specific business needs windows server 2012 datacenter features free DR expectations. Conclusion In this blog post, we have discussed the new and updated features that were introduced with Hyper-V R2.
Each of these features and capabilities are unique and they were specifically designed to improve security, flexibility, and resiliency of your virtual infrastructure. New maximum limits ensure that you can create, manage, and monitor large-scale VMs, which allows you to achieve the highest levels of performance and scalability.
Hyper-V R2 has a windws limited functionality when compared to Windows Server However, the new and updated feature set of the Microsoft hypervisor makes it a cost-effective and reliable solution, suitable for consolidating multiple VMs on a single virtualization platform.
