Microsoft SQL Server 2008 R2 Enterprise Edition with 2 Core License
Microsoft SQL Server 2008 R2 Enterprise Edition with 2 Core License is designed for large organizations that need 24/7 availability and that have high-demand database processing and access requirements, in addition to the need for maximum scalability and rapid application development and deployment with the greatest levels of data protection.
Microsoft SQL Server 2008 R2 Enterprise Edition with 2 Core License enables you to license access at the CPU level of the server, as opposed to buying individual licenses for each person who will access your databases in any way (a simple rule of thumb is that if you query the server, which all SQL-based applications do, then you have to have a license to use the server).
For large organizations, this can be a much more cost-effective way to license Microsoft SQL Server 2008 R2.
Microsoft’s core licensing is always a bit difficult to get a handle on, so we’ll do our best to explain how it works so that you know what you need for your organization (and, of course, call our customer support team if you need additional help with this).
Each processor in your server must be licensed to run Microsoft SQL 2008 R2 Enterprise Edition. A single processor has 4 cores, while high-end processors can have 32 or more cores. Most servers have either dual-core processors (8 cores) or quad-core processors (16 cores).
So, let’s make it practical. You have a server with two dual-core processors that you want to install Microsoft SQL Server 2008 R2 Enterprise on. Each dual-core processor has 8 cores. You have 2 of them, so your total number of cores is 16. Therefore, you will need to buy 8 copies of Microsoft SQL 2008 R2 Enterprise Edition with 2 Core Licenses for your server.
