Licensing two servers, each with a single processor, requires a total of two licenses, and licensing a server that contains four processors requires two licenses. Both server editions include the same technical features and capabilities and differ only with respect to virtualization use rights. The Datacenter edition license provides the right to run an unlimited number of virtual machines VMs on the licensed server, while each Standard edition license allows up to two Windows Server-based VMs.
Multiple Standard edition licenses can be assigned to a single server "stacking" to increase the number of simultaneous VMs allowed. While this has been the least expensive licensing approach for scenarios involving 10 or fewer simultaneous VMs, it can be more expensive overall when the administrative overhead associated with software license compliance checks is factored in.
During a compliance check, customers planning to assert that a server's virtualized Windows Server workloads are covered by stacking Standard edition licenses will likely be asked to demonstrate how the claim is supported. For example, the customer could show that technical constraints in place make it impossible for more than the licensed number of VMs to run simultaneously or that logs from the previous 90 days prove that the maximum number of licensed VMs was never exceeded.
Commonly used to prevent casual or inadvertent disclosure of Office documents and e-mail, RMS protection travels with content and thus can work even if the content is moved to a computer outside an organization's control. This will encourage some customers to accelerate license purchases.
However, the options and timetable for obtaining the current lower prices depends on what type of volume licensing program the customer uses for purchases and the length of time remaining on the current contract. Datacenter edition license. Prices, quoted in U. However, the first time SA is renewed after Nov. Prices for the following offerings will also go up with Datacenter: Starting Nov. For customers using Select and Open, accelerating Datacenter purchases could make sense in two scenarios.
Customer intends to use Windows Server or earlier. Thus, customers with no plans to deploy Windows Server R2 could save by purchasing licenses sooner rather than later. Customer wants SA coverage.
A customer considering whether to buy a Datacenter license with SA just before Nov. 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 eliminates the needs to purchase Essential edition of Server FREE for Firewall. Download Now! Unlike Windows Server Essentials non-R2 , you can now run a single instance of a virtual machine. The server licensing rights have been expanded, allowing you to install an instance of Essentials on your physical server to run the Hyper-V role with none of the other roles and features of the Essentials Experience installed , and a second instance of Essentials as a virtual machine VM on that same server with all the Essentials Experience roles and features.
Definition of a socket is a CPU or physical processor. Logical cores are not counted as sockets. A single license of Standard and Datacenter edition covers up to two physical processors per physical server. Standard edition allows up to 2 virtual instances while the Datacenter edition allows unlimited number of virtual instances. For example, a Windows Server R2 Standard edition installed on a physical server with one socket CPU can support up to two instances of virtual machines.
These virtual machines can be Server R2 Standard or Essentials edition. Both IPv4 and IPv6 are fully supported. 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.
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. 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.
