http://technet.microsoft.com/en-us/library/cc262061(TechNet.10).aspx

Description

Specifies the amount of data that can be read from the server running Microsoft SQL Server at one time.

Note:
This property is available only from the command line.

Syntax

stsadm -o setproperty

-propertyname large-file-chunk-size

-propertyvalue

[-url ]

The syntax for the getproperty operation is:

stsadm -o getproperty

propertyname large-file-chunk-size

[-url ]

Note:
You can substitute -pn for -propertyname and -pv for -propertyvalue.

Property values

The following table shows possible values.

Name	Value
propertyname	Gets or sets the name of the property.
propertyvalue	The upload size in bytes. Content consisting of a single file or groups of files cannot be greater than this setting. The default value is 5 megabytes (MB). In certain circumstances, this value can be changed to any value up to 2 GB (2047 MB).
url	Typically, a path to the URL of the Web application, in the form http://server_name.

Remarks

If you have a file that is greater than your chunk size (for example, 70 megabytes (MB) when the chunk size is set to 5 MB), the file would be read in 14 chunks (70/5). The chunk size is not related to the maximum upload file size. The chunk size simply specifies the amount of data that can be read from a file at one time.

Note:
If the chunk size is raised too high, the files might use up too much front-end memory and you may need to lower this setting After making a change to this property, you must restart IIS. You can restart IIS by typing iisreset at a command-line prompt.

Examples

To set the large file chunk size to 500 MB, use the following syntax:

stsadm -o setproperty -pn large-file-chunk-size -pv 500

To view the current setting of the large file chunk size property, use the following syntax:

stsadm -o getproperty -pn large-file-chunk-size –url http://server_name
