Installation requirements vary based on your application needs. The different editions of SQL Server accommodate the unique performance, runtime, and price requirements of organizations and individuals. The SQL Server components that you install also depend on your specific requirements.

The following sections help you understand how to make the best choice among the editions and components available in SQL Server. Try SQL Server! Deployments must comply with the licensing guide.

For more information, see our pricing and licensing page. A client components installation is also a good option if you administer an instance of SQL Server on a database server, or if you plan to develop SQL Server applications.

Client tools include the client connectivity components used by an application connecting to an instance of SQL Server. Although you can install an instance of SQL Server on a computer that is running IIS, this is typically done only for small Web sites that have a single server computer.

Most Web sites have their middle-tier IIS systems on one server or a cluster of servers, and their databases on a separate server or federation of servers. By default, none of the features in the tree are selected.

Use the information in the following tables to determine the set of features that best fits your needs. There are no limits under the Core-based Server Licensing model. On Standard edition there is support for two nodes. The default packet size is 4 KB, and is controlled by the network packet size configuration option.

Before SQL Server , all versions supported bytes for all index types. The maximum number of bytes in a clustered index key cannot exceed in SQL Server. For a nonclustered index key, the maximum is bytes. You can define a key using variable-length columns whose maximum sizes add up to more than the limit. However, the combined sizes of the data in those columns can never exceed the limit. In a nonclustered index, you can include extra non-key columns, and they do not count against the size limit of the key.

The non-key columns might help some queries perform better. No limit for a hash index, as long as all index keys fit in-row. On a memory-optimized table, a nonclustered index cannot have key columns whose maximum declared sizes exceed bytes.

It is irrelevant whether the actual data in the key columns would be shorter than the maximum declared sizes. For a hash index key, there is no hard limit on size. For indexes on memory-optimized tables, there is no concept of included columns, since all indexes inherently cover of all columns. Did you know that you can edit SQL content yourself?

One or more virtual processors are allocated to exactly one virtual machine. Zero or one virtual processor is mapped to zero or more logical processors. When the mapping of virtual processors to logical processors is: One to zero, it represents an unbound logical processor not used by the guest operating systems.

One to many, it represents an overcommit.
