NetApp Confidential Limited Use 18数据结构和IO路径:Pure： 使用传统位置定位映射表、链接表、重删表、中间表等等所有数据保存在SSD，通过Cache加速位置寻址只是单层映射，即LBA-位置，因此位置和元数据是紧耦合的关系，数据移动需要更新元数据，重删实现需要附加的表格和索引。位置寻址适合所有的控制器都可以全局访问元数据的架构，XtremIO/SolidFire：内容定位，元数据保存在

18、控制器中的SSD中，但是全部运行在内存中而内容存储方式采用两层元数据映射LBA-块ID-位置，物理位置和元数据是松耦合，灵活性更好，天然就支持重删。而内容寻址适合大规模全局重删和分布式架构。全闪存竞争全景图 2015 NetApp, Inc. All rights reserved. NetApp Confidential Limited Use 19数据清除:重删环境下比较复杂，需要判断是否被引用Pure： 采用表验证的方式，定期回收空间时，检查各种表是否引用某数据，如没有则删除XtremIO：而XtremIO采取的是引用计数的方式。原理其实很简单，块的元数据（块ID-位置映射）包含一个引用计数，“写”一次计数就加一，重写时旧的块（其实就是删除）就减一。SolidFire:SF采用的方法是标记&扫除GC的方式。效率最高每隔一定的时间，所有的块都标记为未使用。卷的元数据创建当前使用的块ID的Bloom Filters, 送到块层，在布隆滤波器里面的块就标志为“在用”，在GC结束后没有在用的块就删除了。这样周而复始。全闪存竞争全景图 2015 NetApp, Inc.
