On May 21 st , Windows Server R2 was introduced and is now the latest version of Windows Server in the market. Microsoft has released four different editions of Windows Server varying in cost, licensing and features.
This edition of Windows Server is targeted towards small businesses of up to 15 users. Foundation edition can be implemented in environments where features such as file sharing, printer sharing, security and remote access are required.
The Windows Server R2 Essentials edition is the next step up, also geared towards small businesses of up to 25 users. Windows Server R2 Essentials edition is available in retail stores around the world making it easy for businesses to install the new operating system without necessarily purchasing new hardware.
Windows Server R2 Essentials edition can run a single instance of virtual machine on Hyper V, a feature that was not available in Windows Server Essentials non-R2 edition. This single virtual machine instance can be Windows Server R2 Essential edition only, seriously limiting the virtualization options but allowing companies to begin exploring the benefits of the virtualization platform.
The Standard edition is able to support an unlimited amount of users, as long as the required user licenses have been purchased. We should note that the Standard edition supports up to 2 Virtual Machines. The Windows Server R2 Datacenter edition is the flagship product created to meet the needs of medium to large enterprises. The major difference between the Standard and Datacenter edition is that the Datacenter edition allows the creation of unlimited Virtual Machines and is therefore suitable for environments with extensive use of virtualization technology.
Before purchasing the Windows Server operating system, it is very important to understand the difference between various editions, the table below shows the difference between the four editions of Windows Server For example, a CAL assigned to a user, allows only that user to access the server via any device.
Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server.
We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach:. Assume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations. In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server.
In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devices , e. Windows Server Foundation is available to OEMs Original Equipment Manufacturers only and therefore can only be purchased at the time of purchasing a n new hardware server.
Windows Foundation edition supports up to 15 users. In addition, Foundation edition owners cannot upgrade to other editions. The Essential edition of server is available to OEMs with the purchase of new hardware and also at retail stores. The user limit of this server edition is 25 and device limit is This means that a maximum of 25 users amongst 50 computers can access the Windows Server Essentials edition. For example, you have 20 users rotating randomly amongst 25 computers accessing the Server Essentials edition, without any problem.
A common question at this point is what if the organization expands and increases its users and computers? In these cases Microsoft provides an upgrade path allowing organizations to upgrade to the Windows Server Standard or Datacenter edition license and perform an in-place license transition.
Once the transition is complete, the user limitation, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server should keep in mind that it will be necessary to purchase the required amount of CALs or DALs according to their users or devices.
Administrators will be happy to know that it is also possible to downgrade the Standard edition of Server to the Essentials edition. For example, it is possible to run Essential edition of Server as virtual machine utilizing one of two available virtual instances in Standard edition as shown in the figure below. 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 you 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 storage 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 SAN 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. In case required 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 default in Hyper-V R2. However, to check if this is, indeed, the case, run the following command:.
To check if this feature is available 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 to 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 used for planned or emergency 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 replication of the selected VM to a specific replica server.
If you want to learn more about creating a bootable USB flash drive, read this article on the official Microsoft page. This feature is used to provide 3D graphics virtualization of the guest OSes 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 to verify that the Remote FX adapter has been successfully created. This feature ensures 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 incoming traffic among multiple physical CPUs.
In Hyper-V R2, this feature has been updated 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:.
