concept/conbody body conbody"> <p class="- topic/p p">RAID 6 通过结合使用数据分条和奇偶校验信息来提供数据冗余。与 RAID 5 类似，奇偶校验在各条带上分布。然而，RAID 6 使用额外的物理磁盘存放奇偶校验，这样磁盘组中的每个条带都有两个具有奇偶校验信息的磁盘块。额外的奇偶校验在两个磁盘失败时提供数据保护。在下面的图像中，两组奇偶校验信息表示为 <span class="ph uicontrol">“P”</span> 和 <span class="ph uicontrol">“Q”</span>。</p><img class="- topic/image image"
