Virtualization Rights You can run up to two Hyper-V virtual machines or containers or one physical instance with a standard license. If you use the Hyper-V role only on a physical instance, you can use it as a Hyper-V host, and then host two Hyper-V virtual machines on that host.
If you want to use multiple roles on a physical instance, you cannot start the virtual machine on top with the same license. Licensing model based on the core. Client licenses are required for each user or device that connects indirectly or directly to the server. For example, if you use the server as a file server, you will need a CAL for each user account or computer that accesses this file server on the network.
Virtualization Rights The unlimited number of virtual machines or Hyper-V containers. As stated above, you will buy licenses depending on how many cores you have on the hosts. At this point, you can run as many virtual machines as you like on the hosts using any role. Licensing model based on cores. Make sure that you do not accidentally select this release when installing on a physical server that does not host virtual machines.
Client licenses are required for each user or device that connects indirectly or directly to servers in your environment. Although the prices for Windows Server R2, , are the same, if you are using a standard license or a Datacenter license for Windows Server or later, there are some key changes that you need to be aware of.
Thus, if you have a server containing 2 processors with 24 cores, in Windows Server you will only need to buy one Standard or Datacenter license. In Windows Server , you will have to buy licenses for all 24 cores. This becomes quite difficult, as there are many rules, but the main thing is that if you have a core server, the costs will be approximately the same. However, OS licensing may be more expensive on servers with a higher core density. Despite the change to the core license, the virtualization rules remain the same in Windows Server and later.
Once you have licensed all your cores on the server, with the standard version you get 2 licenses for the Windows Server guest OS compared to the unlimited number in the Datacenter version. Also, the features in Windows Server Standard and Datacenter were the same. But some features of Windows Server , such as Storage Spaces Direct or shielded virtual machines, are only available in the Datacenter release.
Standard and Datacenter editions offer a variety of installation options. These options affect what features will be available after installation, such as a graphical user interface and a set of services.
The following installation options are available:. Desktop Experience is an installation option that most people are familiar with. This option installs most of the functions and roles out of the box, including the desktop GUI. You will receive the Server Manager, which allows you to add and remove roles and components.
Web and application platform. Windows Server R2 builds on the tradition of the Windows Server family as a proven application platform, with thousands of applications already built and deployed and a community of millions of knowledgeable and skilled developers already in place. Windows Server R2can offer your organization even greater application flexibility. You can build and deploy applications either on-premises or in the cloud—or both at once, with hybrid solutions that work in both environments.
Access and information protection. With the new capabilities in Windows Server R2, you will be able to better manage and protect data access, simplify deployment and management of your identity infrastructure on-premises and across clouds, and provide your users with more secure remote access to applications data from virtually anywhere and any device.
Virtual desktop infrastructure. VDI technologies in Windows Server R2offer easy access to a rich, full-fidelity Windows environment running in the datacenter, from virtually any device. With Windows Server R2, it is now easier than ever for organizations to take advantage of the cost savings of virtualization and make the optimum use of server hardware investments by consolidating multiple server roles as separate virtual machines.
You can use Hyper-V to efficiently run multiple operating systems — Microsoft Windows, Linux, and others — in parallel, on a single server. IT demands: Support for demanding, critical business workloadsThis means IT wants bigger, better, faster and more available virtual machines; IT also wants to use their new servers as they come out and be able to fully leverage the raw power that the servers provide.
WS12R2 delivers: Enterprise-class scale and performanceYou can achieve greater densities and run more demanding workloads through the scale and performance improvements of Windows Server R2. Within your organization, as you virtualize more of your infrastructure, you need to have a platform, a hypervisor, that can support your most demanding workloads.
Then, as you adopt newer hardware, you will need to be able to utilize the advancements within the hardware to the fullest, without losing the capability of the existing investments in infrastructure you already have.
The new VHDX format in Windows Server is better suited to address the current and future requirements for running enterprise-class workloads. It has much larger capacity and additional resiliency. VHDX supports up to 64 terabytes of storage. It also provides additional protection from corruption from power failures by logging updates to the VHDX metadata structures and prevents performance degradation on large-sector physical disks by optimizing structure alignment.
IT demands: Increased flexibility to move resources and workloadsThis means IT wants the flexibility to move virtual machines wherever it would be best to run them whether on premises or at a Service Provider. It also includes the ability to offer VM guests flexible clustering options.
WS12R2 delivers: Virtual Machine MobilityWindows Server R2 allows you to manage virtual machines independently of their underlying physical infrastructure. It also enables you to handle changes in resource demand as they occur and gives you the ability to rebalance running virtual machines either through the servers which the VMs reside on, or the storage resources used by the virtual machines.
This is useful, for example, in a branch office where you may be storing the virtual machines on local disk, and you want to move a VM from one node to another. This is also especially useful when you have two independent clusters and you want to move a virtual machine, live, between them, without having to expose their shared storage to one another. Unlike competing guest clustering that does not support file-based storage, shared VHDX files can be stored on a scale-out file server cluster or on Cluster-shared Volumes CSV on block storage.
Unlike competing guest clustering options, shared VHDX clustering preserves dynamic memory, live migration and storage live migration for a VM that is part of the guest cluster. It also allows an administrator to easily test the replica virtual machine without disrupting the ongoing replication.
If a disaster occurs at the primary site, administrators can quickly restore their business operations by bringing up the replicated virtual machine at the Replica site. IT demands: Leverage existing cross-platform investmentsMany enterprises and service providers are running a mix of hypervisors, operating systems and applications.
Often times, migrating from one platform to another, if even a goal, is either not easily feasible from a technical standpoint, or a much bigger project than IT organizations are willing to take on.
WS12R2 delivers: First-class citizen guest support for LinuxWindows Server R2 has been designed to support a heterogeneous datacenter and cloud infrastructure by adding comprehensive functional support for Linux guests running on top of Hyper-V.
A number of improvements were made for Windows guests in Windows Server , and new in Windows Server R2, these improvements are now also available to Linux guests running on top of Hyper-V; they include:Minimum memory setting — being able to set a minimum value for the memory assigned to a virtual machine that is lower than the startup memory settingHyper-V smart paging — which is paging that is used to enable a virtual machine to reboot while the Hyper-V host is under extreme memory pressureMemory ballooning — the technique used to reclaim unused memory from a virtual machine to be given to another virtual machine that has memory needsRuntime configuration — the ability to adjust the minimum memory setting and the maximum memory configuration setting on the fly while the virtual machine is running without requiring a reboot.
Linux Integration Services included in key standard distrosUp until now, if you wanted to take advantage of Linux Integration Services LIS for your Hyper-V environment, you had to go to the Microsoft download center, download the correct LIS package for your Linux distribution, and then manually install it on your Hyper-V servers. Lets consider a simplistic scenario:You have a client and server. You assimilate all these packets into the k data that you asked for and send it back up.
All this takes CPU resources. You cant send the entire k at once no matter how fast your NIC is. You still have to chop it down into small packets and send it up and down the stack. Your CPU is just busy doing this over and over again. How does it work — I need to read k of data. First I find out a place in memory where that data should reside, then I register that with the NIC and get a token back.
I send this token back to the other side through SMB direct and say I need to read k of data. So the two NICs actually do the transfer. The two CPUs are now busy doing something else. RDMA can be incredibly fast — ms latency when doing transfers. This means that live migrations can now take advantage of high-speed networking, and they can also stream over multiple networks for improved bandwidth.
This copy is performed by transferring the contents of the VHD between the two servers over the IP connection between the Hyper-V hosts. Note: This slide is animated and has 1 clickDynamic Memory was introduced with Windows Server R2 SP1 and is used to reallocate memory between virtual machines that are running on a Hyper-V host.
Improvements made within Windows Server Hyper-V includeMinimum memory setting — being able to set a minimum value for the memory assigned to a virtual machine that is lower than the startup memory settingHyper-V smart paging — which is paging that is used to enable a virtual machine to reboot while the Hyper-V host is under extreme memory pressureMemory ballooning — the technique used to reclaim unused memory from a virtual machine to be given to another virtual machine that has memory needsRuntime configuration — the ability to adjust the minimum memory setting and the maximum memory configuration setting on the fly while the virtual machine is running without requiring a reboot.
Because a memory upgrade requires shutting down the virtual machine, a common challenge for administrators is upgrading the maximum amount of memory for a virtual machine as demand increases. Because of an increase in the size of the databases, the virtual machine now requires more memory. In Windows Server R2 with SP1, you must shut down the virtual machine to perform the upgrade, which requires planning for downtime and decreasing business productivity.
With Windows Server , you can apply that change while the virtual machine is running. Then, the Hot-Add memory process of the VM will ask for more memory and that memory is now available for the virtual machine to use. Note: This slide is animated and has 2 clicksHyper-V Smart Paging is a memory management technique that uses disk resources as additional, temporary memory when more memory is required to restart a virtual machine.
This approach has both advantages and drawbacks. It provides a reliable way to keep the virtual machines running when no physical memory is available. However, it can degrade virtual machine performance because disk access speeds are much slower than memory access speeds.
To minimize the performance impact of Smart Paging, Hyper-V uses itonly when all of the following occur:The virtual machine is being restarted. No physical memory is available. No memory can be reclaimed from other virtual machines that are running on the host. Hyper-V Smart Paging is not used when:A virtual machine is being started from an off state instead of a restart. Oversubscribing memory for a running virtual machine would result.
A virtual machine is failing over in Hyper-V clusters. Hyper-V continues to rely on internal guest paging when host memory is oversubscribed because it is more effective than Hyper-V Smart Paging. With internal guest paging, the paging operation inside virtual machines is performed by Windows Memory Manager.
Windows Memory Manager has more information than does the Hyper-V host about memory use within the virtual machine, which means it can provide Hyper-V with better information to use when it chooses the memory to be paged.
Because of this, internal guest paging incurs less overhead to the system than Hyper-V Smart Paging. In this example, we have multiple VMs running, and we are restarting the last virtual machine.
Normally, that VM would be using some amount of memory between the Minimum and Maximum values. In a hybrid cloud world, customers are looking at their datacenters as datacenters without boundaries — i. To enable hybrid clouds for them, they need networking infrastructure that scales to growing demand and changes and that can support workload mobility cross datacenters.
WS12R2 delivers: Software-defined network infrastructureSoftware-defined networking enhances the management of modern networks by providing the ability for applications to control access to network resources dynamically.
A key enabler of SDN is that it uses networking functionality that has been moved to the virtual switch, providing the ability to modify packets in transit and enabling integration of more advanced switch extensions. Finally, SDN also brings the benefit of unifying the management of both the physical and virtual infrastructure.
On the same physical network, with Hyper-V Network Virtualization, you can run multiple virtual network infrastructures and you can have overlapping IP addresses with each virtual network infrastructure acting as if it was the only one running on the shared physical network infrastructure. Cross-premises connectivity enables enterprises to connect to private subnets in a hosted cloud network. It also enables connectivity between geographically separate enterprise locations.
However, some of the limitations of this feature were that you needed one gateway per tenant two for HA , you could only do host-level clustering, there were limited routing capabilities and a lack of Internet NAT.
In Windows Server , the hoster would have to provide a separate server to server S2S virtual private networking VPN virtual machine for each customer or implement a third-party multi-tenant VPN gateway.
Now with Windows Server R2, you no longer require a separate third-party multi-tenant VPN gateway, as this feature is now built in to the operating system. This function can provide a seamless connection over a S2S VPN link between multiple external organizations and the resources that those organizations own in a hosted cloud. It also enables connectivity between physical and virtual networks, enterprise data centers, and hosting organizations, and between enterprise networks and Windows Azure.
High availability is provided through guest clustering using a hot standby node available. A dynamic link library ensures any routing configuration is synced from the active node to the hot standby, and when the standby becomes active, the routing configuration is applied. With the explosion of datacenters the need to automate management of such devices in a consistent way is more important than ever.
As a continuation of this effort, Windows Server R2 includes a device management abstraction layer — referred to as the datacenter abstraction layer DAL - that further reduces the complexity of heterogeneous device management. Windows Server R2 will allow customers to 1 enable device management using a common abstraction layer, working over standard protocol and schema; 2 move from a complex datacenter device world into a world of well-defined, standard based components; and 3 build ready to use solution for device management right in Windows.
IT demands: Continuously available and resilient network infrastructure:IT needs to help ensure that services are running continuously without any interruption. This means that there is automatic recovery from both software and hardware failures, with the need for an IT Pro or network administrator to fix issues in the middle of night now eliminated. WS12R2 delivers: High-performance networking:Customers want to get the best performance out of the hardware they have — whether they are industry standard hardware or high end hardware that they have already invested in.
Poor network performance are primarily because of two reasons — limitations in network bandwidth, limitations in the processing power -, and these typically affect availability and resiliency of the network infrastructure directly.
A considerable amount of work has been done in Windows Server R2 to extract great and predictable performance inbox, as well as to make the most out of next generation hardware. SR-IOV works in conjunction with system chipset support for virtualization technologies that provide remapping of interrupts and Direct Memory Access, and allows SR-IOV-capable devices to be assigned directly to a virtual machine.
This increases network throughput and reduces network latency while also reducing the host CPU overhead required for processing network traffic. You can configure your systems to maximize the use of host system processors and memory to effectively handle the most demanding workloads. These Hyper-V features let enterprises take full advantage of the largest available host systems to deploy mission-critical, tier-1 business applications with large, demanding workloads.
And unlike with competitive implementations of SR-IOV, key features such as live migration, high availability and fault tolerance are still supported. WS12R2 delivers: Improved manageability and diagnostics:Windows Server R2 builds on the networkingadvances in Windows Server with an array of new and enhanced features that help reduce networking complexity while lowering costs and simplifying management tasks.
With Windows Server R2, IT administrators have tools to automate and consolidate networking processes and resources. Among other things, new features and updates in Windows Server R2 include:Resource metering:Hyper-V in Windows Server R2 helps providers build a multitenant environment in which virtual machines can be served to multiple clients in a more isolated and secure way.
Because a single client may have many virtual machines, aggregation of resource use data can be a challenging task. However, Windows Server R2 simplifies this task by using resource pools, a feature available in Hyper-V.
The average physical memory, in megabytes, used by a virtual machine over a period of time. The lowest amount of physical memory, in megabytes, assigned to a virtual machine over a period of time. The highest amount of physical memory, in megabytes, assigned to a virtual machine over a period of time. The highest amount of disk space capacity, in megabytes, allocated to a virtual machine over a period of time.
The total incoming network traffic, in megabytes, for a virtual network adapter over a period of time. The total outgoing network traffic, in megabytes, for a virtual network adapter over a period of time. The QoScmdlets support both the QoS functionalities available in Windows Server R2—such as maximum bandwidth and priority tagging—and new features that became available in Windows Server , such as minimum bandwidth.
QoS minimum bandwidth benefits vary from public cloud hosting providers to enterprises. DNS traffic management:There has been increasing demand for a feature where the customer can control the resolution of certain DNS records based on the client information.
With the advent of global markets and hosted server farms serving to different part of the world, providing geo-politically apt answers to DNS queries is required for better Quality of Service to end users.
For the enterprise customers who want to deploy split-horizon DNS to separate the internal and external queries, maintaining two different versions of the server is a management headache. A solution to this problem is to allow customers to maintain the records at the same place while deciding resolution policies based on the incoming query. To transform networking, customers need to think about networking in the same way that they think about compute — i.
They also need to think about how to reduce operational complexity in networking. Finally, they need a solution that can seamlessly bridge on-premises and off-premises networks.
It turns out that our key learning is centered around the promises of flexibility, automation and control. This needs to be reiterated as it is the foundation of our software-defined promise and solves a key customer need today. Many customers have asked us for the ability to deeply integrate Hyper-V networking into their existing network infrastructure, their existing monitoring and security tools, or with other types of specialized functionality — to meet that need, Windows Server also introduced the Hyper-V Extensible Switch that enables easy extensions of our hypervisor platform.
Simultaneously, the gateway will be multitenant aware and hence enables the service provider to drive operational efficiency by enabling multiple customer connections terminate on it. Self-service virtual network provisioning and management — Enterprises can easily connect their on-premises infrastructure to service providers by using a self-service experience to provision and manage connectivity and access.
Standards-based automated network switch configuration - Transforming the datacenter involves abstracting storage, compute and network resources from their underlying physical hardware and manage them in a standardized manner.
We will continue to work with these partners to offer customers the choice of networking solutions to best meet their needs. Note to presenter: 3 clicks to complete build. Windows Server helps you provide fault tolerance on your network adapters without having to buy additional hardware and software.
Windows Server includes NIC Teaming as a new feature, which allows multiple network interfaces to work together as a team, preventing connectivity loss if one network adapter fails. It allows a server to tolerate network adapter and port failure up to the first switch segment. In Windows Server R2, the load-balancing algorithms have been enhanced with the goal to better utilize all NICs in the team, significantly improving performance.
The advantages of a Windows teaming solution are that it works with all network adapter vendors, spares you from most potential problems that proprietary solutions cause, provides a common set of management tools for all adapter types, and is fully supported by Microsoft. Teaming network adapters involves the following:NIC Teaming configurations. Algorithms for traffic distribution. Several different algorithms distribute inbound and outbound traffic between the network adapters.
Windows Server introduced IP Address Management IPAM , a framework for discovering, monitoring, auditing, and managing the physical IP address space and the associated infrastructure servers on a corporate network. Windows Server R2 adds virtual IP address space management. This mode of deployment is largely preferred to reduce network latency in managing infrastructure servers from a centralized IPAM server. Centralized, where one IPAM server is deployed in an enterprise.
