sql server 2008 standard x86 x64 簡體中文 DVD |
The background is the size of the memory.
An x86 server system can manage a maximum of 4 GB of memory. This limits the addressable memory space for Windows server 2003 systems to 4 GB. (This is true for all 32-bit operating systems). With 2 GB reserved for the operating system by default on 32-bit Windows, only 2 GB of memory remains for SQL 2000 or SQL Server 2005 x86. You can increase this amount to 3 GB by setting a /3GB switch in a Windows BOOT.INI. In order to use more than 4 GB of memory AWE must be enabled. AWE is a set of memory management extensions to the Microsoft Win32 API that allows SQL Server x86 to address memory beyond 4 GB. Using AWE, applications can acquire physical memory as nonpaged memory, and then dynamically map views of the nonpaged memory to the 32-bit address space. AWE enables SQL Server 2000 and 2005 x86 to address larger amounts of data. Now, this is old news, everybody knows that.
