Original: SQL Server: Understanding IAM pagesIn previous articles, we discussed data pages, GAM and Sgam, and PFS pages. Today we will discuss the Index allocation Mapping (index Allocation Map:iam) page.In SQL Server 2005 and later versions, the allocation unit (allocation units) has the following three types:
