In this way, mapping of placement groups (and replicas) to storage devices does not rely on any metadata but instead on a pseudo-random mapping function.
这样一来，放置组(以及副本)到存储设备的映射就不用依赖任何元数据，而是依赖一个伪随机的映射函数。
Finally, the mapping of the placement group to object storage devices is a pseudo-random mapping using an algorithm called Controlled Replication Under Scalable Hashing (CRUSH).
最后，放置组到对象存储设备的映射是一个伪随机映射，使用一个叫做Controlled Replication Under Scalable Hashing (CRUSH)的算法。
