The Storman.aspx page is removed from SharePoint Server 2010

In Microsoft SharePoint Server 2010, the Storman.aspx page is removed.

This problem occurs because the Storman.aspx page is likely to cause SQL blocking. This page affects the performance of the content database that your site belongs to.

The Storman.aspx page is used for storage management. For example, the page can show you the top 100 documents or document libraries in terms of size. Therefore, you can use the page to clean up some content from your site by deleting the large content that you no longer need. Because there is no replacement for this page, use one of the following methods to regain certain functionalities:

• Use Web analytics reports to analyze various aspects of sites and of site collections. For more information about the reports, visit the following Microsoft TechNet Web site:
  View Web analytics reports (SharePoint Server 2010) (http://technet.microsoft.com/en-us/library/ee663487(office.14).aspx)
• Verify the version information of each document on the Version History page. To do this, follow these steps:
  1. Open the SharePoint Server Web site that contains the document.
  2. Point to the name of the document, click the drop-down list, and then click Version History.
• Use Windows Explorer to check the sizes of the documents that are in a document library. To do this, follow these steps:
  1. Click the document library name in SharePoint 2010 Central Administration.
  2. On the Library tab, click Open with Explorer.
  3. Right-click a document, and then click Properties.
  4. On the General tab, view the size of the document.
• Use the SPSite.StorageManagementInformation method to return information about storage management for the site collection. For more information about the method, visit the following Microsoft Developer Network (MSDN) Web site:
  SPSite.StorageManagementInformation method (Microsoft.SharePoint) (http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spsite.storagemanagementinformation.aspx)

This behavior is by design.
