Flexible - This method allows you to create a cluster with fewer, yet a more flexible number of data drives (255 max per cluster).
This method does not require organizing your disks into columns and rows and allows for the use of all deduplication data drives in a cluster, rather than a row-by-row utilization of drives.
***With Flexible storage, each node in a cluster has a single hash range and all data drives for the node store data for the node's hash range.***
Note that if you select this method, you will not be able to add deduplication nodes in the future to increase your cluster size.

hash range 是什么？ *** 句子怎样翻译理解？谢谢！
