Aug 27, · I just completed a server upgrade project last night. We moved one of our SQL servers from Server with SQL on old hardware, to Server R2 with SQL on newer hardware by doing a fresh installation of everything. We own a license key for Server R2 Datacenter, but I installed Standard/5(67). A: Windows Server R2 introduces a new feature, AVMA, which allows VMs running Windows Server R2 to automatically activate, provided the Hyper-V host they're running on is Windows Server R2 Datacenter and is itself activated. To tell the VM to use AVMA, you need to give the VM a specific key (this acts very similar to the keys. Jan 07, · Automatic virtual machine activation is an easy to miss, but really handy feature in Windows Server R2. One of the primary reasons why people buy Windows Server Datacenter today is because it gives them license to run an unlimited number of Windows Server instances inside of .
A server with 2 Intel Xeon E5 processors with 10 cores each has 2 processors. It requires one Window Server license. It needs 2 Windows Server licenses. This applies no matter what downgraded version you plan to install.
Downgrade Rights According to Microsoft: If you have Windows Server R2 Datacenter edition you will have the right to downgrade software bits to any prior version or lower edition. If you have Windows Server R2 Standard edition, you will have the right to downgrade the software to use any prior version of Enterprise, Standard or Essentials editions. With one exception, which is really due to the exceptional virtualization licensing rights granted with the Datacenter edition. Very nice for multi-tenant or Network Virtualization-enabled clouds.
Virtualization Rights Everything in this section applies to Windows Server licensing on all virtualization platforms on the planet outside of the SPLA hosting licensing program.
The key difference between Std and DC is the virtualization rights. In other words: Say you license a host with the DC edition of Windows Server. You cannot transfer those VOSEs licenses to another host. You can transfer a volume license of DC or Standard for that matter once every 90 days to another host.
The VOSEs move with that host. Say you license a host with the Std edition of Windows Server. You can transfer a volume license of Standard or DC for that matter once every 90 days to another host. Say you license a host with 3 copies of the Std edition of Windows Server.
This is an accounting operation. You do not install Windows 3 times on the host. You do not install 3 license keys on the host. If you need HA or Live Migration then you license all hosts for the maximum number of VMs that can not will run on each host, even for 1 second. The simplest solution is to license each host for the DC edition. WS server licenses require one of the following to be upgraded: In the new Processes tab, the processes are displayed in varying shades of yellow, with darker shades representing heavier resource use.
It lists application names and status, as well as CPU, memory, hard disk and network utilization. The process information found in the older versions are now moved to the new Details tab.
The CPU tab no longer displays individual graphs for every logical processor on the system by default; instead, it can display data for each non-uniform memory access NUMA node.
When displaying data for each logical processor for machines with more than 64 logical processors, the CPU tab now displays simple utilization percentages on heat-mapping tiles. The color used for these heat maps is blue, with darker shades again indicating heavier utilization. Additionally, a new Startup tab has been added that lists startup applications,however this tab does not exist in Windows Server Both IPv4 and IPv6 are fully supported.
Active Directory in Windows Server is now aware of any changes resulting from virtualization, and virtualized domain controllers can be safely cloned.
Upgrades of the domain functional level to Windows Server are simplified; it can be performed entirely in Server Manager. Active Directory Federation Services is no longer required to be downloaded when installed as a role, and claims which can be used by the Active Directory Federation Services have been introduced into the Kerberos token.
Many new features have been added to Hyper-V, including network virtualization, multi-tenancy, storage resource pools, cross-premises connectivity, and cloud backup. Additionally, many of the former restrictions on resource consumption have been greatly lifted. Each virtual machine in this version of Hyper-V can access up to 64 virtual processors, up to 1 terabyte of memory, and up to 64 terabytes of virtual disk space per virtual hard disk using a new.
Up to virtual machines can be active per host, and up to can be active per failover cluster. ReFS Main article: Major new features of ReFS include: Metadata and file data are organized into tables similar to a relational database. The file size, number of files in a folder, total volume size and number of folders in a volume are limited by bit numbers; as a result ReFS supports a maximum file size of 16 Exabytes, a maximum of Free space is counted by a hierarchical allocator which includes three separate tables for large, medium, and small chunks.
File names and file paths are each limited to a 32 KB Unicode text string. Built-in resilience ReFS employs an allocation-on-write update strategy for metadata, which allocates new chunks for every update transaction and uses large IO batches.
All ReFS metadata has built-in bit checksums which are stored independently. If nevertheless file data or metadata becomes corrupt, the file can be deleted without taking the whole volume offline.
ReFS seamlesslyintegrates with Storage Spaces, a storage virtualization layer that allows data mirroring and striping, as well as sharing storage pools between machines.
Sign in Windows Server R2 Windows Server R2 captures the experience Microsoft has gained from building and operating public clouds to deliver a highly dynamic, available, and cost-effective server platform for your datacenter and private cloud. The following information provides an overview of your key licensing options.
Licensing editions Compare features in all editions to determine the ideal solution for your virtualization and cloud computing needs. Datacenter Datacenter edition is ideal for customers who want to have a highly virtualized private and hybrid cloud environment. As always, it provides access to all the product features and enables unlimited instances of Windows Server with each license, enabling your virtual environment to grow as you do. The licensing for Datacenter edition will continue to be processor plus CAL Client Access License , with each license covering up to two physical processors on a single server.
Standard Standard edition is ideal for those customers who want to have a physical or lightly virtualized environment. This edition enables you to run up to two virtual instances of Windows Server with each license and provides all the same features as Datacenter edition.
The licensing for Standard edition will continue to be processor plus CAL, with each license covering up to two physical processors on a single server, just like Datacenter edition. Essentials Essentials edition is ideal for small businesses that have up to 25 users and want to have a simpler, pre-configured connection to cloud-based services.
This edition enables you to run a single virtual instance of Essentials. The licensing for Essentials will continue to be a server license for a two processor server that does not require CALs. Foundation Foundation edition is ideal for small businesses that have up to 15 users and want a general purpose server.
The licensing for Foundation has not changed; it continues to be a server license for a one-processor server that does not require CALs and is sold only through OEM original equipment manufacturer. FAQ Find answers to questions about features, licensing models, and determining which edition is right for you.
How is Windows Server R2 licensed? Windows Server R2 will continue to have the same licensing model as Windows Server , with two editions available in volume licensing: Standard edition and Datacenter edition. A single license covers up to two physical processors. Here are just a few examples: Enterprise-class virtual machine density, performance, and mobility with best-in-class performance and scale for Microsoft workloads High-performance file-based storage on cost-effective, industry-standard hardware with inbox storage virtualization and tiering Highly available, in-box hybrid networking for bridging physical and virtual networks in a multi-tenant environment and across premises Protection and recovery of assets for all your workloads with simple and affordable disaster recovery options Flexible remote access to corporate resources from virtually anywhere and on any device while helping to protect corporate information How do I determine which Windows Server R2 edition is right for me?
Because there is feature parity between Windows Server R2 Standard and Datacenter editions, your decision will be based on your virtualization strategy, as virtualization rights are the only differentiator between the editions. If your strategy calls for a highly virtualized environment, Datacenter edition will provide you with optimum flexibility because it allows for unlimited virtualization. This edition gives you the elasticity to add and move virtual OSEs across Datacenter licensed servers without needing to track the virtual OSE count on that server.
If you purchase Standard edition today but find you need to expand the virtualization capacity of your licensed server, you can do one of the following: Purchase additional Standard edition licenses and assign them to the same physical server, giving you the rights to run additional instances of Windows Server. The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time.
Purchase a Software Assurance Step-up license to Datacenter edition, changing the license to a higher edition that allows unlimited virtual OSEs. To use this benefit, your underlying license must have Software Assurance. With the Windows Server R2 Standard edition licensing model, you can grow your virtualization environment by either buying a step-up license to Datacenter edition if you have Software Assurance, or by simply buying additional Standard edition licenses and assigning them to the same physical server.
For example, if you have a two-processor server and want to run a total of four VOSEs, you can purchase two Standard edition licenses and assign them to the same server. Additional examples are shown in the following table.
