   我觉得我们应该还是保留Backend这个实体,而不是将Storage全部替换为Backend。
   1. Storage,StorageGroup应该做为Backend的某个属性存在。因为Backend上不仅有Storage的功能还有Compute的能力。
   2. 未来我们想要把我们的Backend解耦成只存储、或者只计算的能力的时候,如果你这里是Storage,那么我们未来还需要引入新的类型。而如果我们保留Backend的话,那么那个时候我们只需要在Backend的Property中增加属性“Compute”、“Ingest”即可
   
   所以我认为我们这里不应该把我们的Backend变成Storage,而Storage只应该是Backend的一个属性。
