### Allowed values for REDUCED_REDUNDANCY storage class

`REDUCED_REDUNDANCY` implies lesser parity than `STANDARD` class. So,`REDUCED_REDUNDANCY` parity drives should be

- Less than N/2, if `STANDARD` parity is not set.
- Less than `STANDARD` Parity, if it is set.

Default value for `REDUCED_REDUNDANCY` storage class is `1`.
