One thing that can be done now is start thinking of ‘cache’ as a capability of a pool rather than a pool type. It is not helped by the fact that at the mome t the default name for a pool still seems to be ‘cache’. Perhaps it should be changed to ‘pool’ or somethibg like that.
I do agree that a better name for the Unraid array that is more type oriented (such as the UnArray’ suggestion, or perhaps simply ‘hybrid’) would be a good idea. It will become much more important when we can have multiple arrays of the type of the current main array, and everythibg starts getting treated as a pool.
