The mapping of virtual memory to physical memory occurs through page tables, which are implemented in the underlying hardware (see Figure 1).
虚拟内存到物理内存的映射通过页表完成，这是在底层软件中实现的(见图1)。
Note that as shown here, a process may have a large address space, but it is sparse, meaning that small regions (pages) of the address space refer to physical memory through the page tables.
注意这里的显示，进程可能有一个大的地址空间，但是很少见，就是说小的地址空间的区域(页面)通过页表指向物理内存。
A DSI occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory (this is a page fault).
如果对当前不在物理内存中加载的虚拟地址进行引用(这是一个页面错误)，则会出现DSI错误。
By default, the system does not allocate any memory to the large page physical memory pool.
在默认情况下，系统并不为大页面物理内存池分配任何内存。
The first page of virtual memory in the kernel address space can be accessed by kernel code, but is marked as read-only.
内核地址空间中的第一页虚拟内存可通过内核代码访问，但是被标记为只读。
It also logs paging space in and outs, file page in and outs, candidate memory and memory references.
此外它还会记录分页空间的进出情况、文件页面的进出情况、候选内存和内存引用。
When an application references a page that is not mapped into real memory, the system generates a page fault.
如果应用程序引用了某个分页，而该分页并没有映射到实际内存中，那么系统将产生一个缺页。
Figure 1 illustrates how virtual pages in a process's address space are mapped to physical page frames in memory.
图1说明了进程地址空间中的虚拟页如何映射到内存中的物理页帧。
LPAR2 (also with 4gb of memory) was busier and at times required more memory and occasionally it would page to paging space.
LPAR2(也有4gb的内存)比较忙，有时候需要更多内存，偶尔会把页面交换到分页空间。
The physical memory block that contains the page is marked as free and ready for reuse for additional pages.
将包含该分页的物理内存块标记为空闲，并为其它的分页做好重用的准备。
Note that in AIX, memory is not really allocated until the page is used.
注意，在AIX中，在使用页面之前，并不实际分配内存。
Once a page is loaded into real memory, it is marked as unmodified.
在将分页加载到实际内存中之后，它将被标记为未经修改的。

Although effective at limiting memory, using a huge page reservation to reduce host available memory may interfere with the host's memory management algorithms in subtle ways.
尽管有效限制了内存，使用大页面保留减少可用内存却可能对客户内存管理算法产生一点小影响。
