You can change the name of the database, file path, file names, size and file Step 1: First we will create a database named "Manvendra" with three dataįiles (1 primary and 2 secondary data files) and one log file by running the below T-SQLĬode. Proportional fill works based on the free space Proportion of free space within each file, which allows the files to become fullĪt approximately the same time. That should be written to each of the data files in a multi-file filegroup based on the This algorithm determines the amount of information The proportional fill algorithm is used when allocating pages, so all data files allocate space around the same time. SQL Server achieves this by an algorithm known as Proportional Pages first to data file 1, then allocates to data file 2, and so on, thenīack to data file 1 again. So if we insert data into a table, SQL Server allocates If multiple data filesĮxist within a filegroup, SQL Server allocates pages to all data files based

When you insert any data into a SQL Server database, it saves theĭata to a series of 8 KB pages inside the data file. Is the fundamental unit of data storage in SQL Server. The disk space allocated to a data file is logically divided into pages which Work as a logical container for the data files and a filegroup can have multiple data Above these operating system files, there are Filegroups. SQL Server databases can have multiple data and log files, but only one Secondary data files are optional andĬan be used to spread data across multiple files/disks by putting each file on a differentĭisk drive. Userĭata and objects can be stored in this file and every database Information for the database and points to other files in the database. Data files can be of two types: Primary or Secondary.

Every SQL Server database has at least two operating system files: a data file and a logįile.
