Many native SQL Server 2005 options exist to help support database growth. From a planning perspective, one of the first topics that should be addressed is filegroups. A filegroup can be considered a logical storage unit to house database objects that maps to a file system file or multiple files. By default each database has a primary filegroup to support the system and user objects. To help support the needed growth and assumed performance, additional disk drives can be allocated to the server. Next, new filegroups and files can be created on the new disk drives. Then objects can be moved to these filegroups as a means to spread the IO over additional disks.
