Chapter 3: Installing SQL Server

The number of two-core packs listed in the second column of Table 3-6, is the number of
two-core packs required for each physical processor. As you may notice, even if you license
a single or dual core processor, you still have to buy enough two-core packs to license the
minimum of four cores. With this four-core minimum license per physical processor require-
ment of SQL Server 2012, it makes more sense to have a single four-core processor than two
dual-core processors.

Server + CAL Licensing
Server + CAL Licensing for SQL Server 20120 is only available for the Standard and Business
Intelligence Editions. Users need a CAL that is the same version or newer than the ver-
sion of the licensed SQL Server they need to access. A SQL Server 2012 CAL can be used
to access multiple licensed SQL Servers, including SQL Server 2012 Standard and Business
Intelligence Editions. These new CALs can also be used for previous versions of SQL Server,
including the Enterprise Editions of 2008 and 2008R2, for which the Server + CAL licensing
model was still available.

Virtual Machine Licensing
Virtual machine licensing of SQL Server 2012 can be done in one of three ways:


  1. Individual VM core licensing: Each individual virtual machine requires a core
    license for each allocated virtual processor. There is a minimum of four core
    licenses required for each virtual machine. This licensing model of virtual
    machines can be very costly, as multiple virtual machines with only one or two
    allocated virtual processors would still require four core licenses each.

  2. Individual VM Server + CAL licensing: Only SQL Server 2012 Standard and
    Business Intelligence Edition can be licensed using the Server + Cal licensing
    model. Each individual VM requires a Server license, and a CAL is needed for each
    user that connects to a licensed server. This type of licensing is great for applica-
    tions with a small number of users.

  3. Host server or server farm core licensing: The total number of cores avail-
    able on a host server or server farm can be licensed to maximize virtualiza-
    tion capabilities and take advantage of full computing power. To fully license a
    host server or server farm, Enterprise Edition core licenses along with Software
    Assurance are required. This type of licensing allows for an unlimited number of
    virtual machines and allows dynamic provisioning and de-provisioning of virtual
    processors.
