In this paper, the authors present a generic framework for constructing systematic minimum storage regenerating codes with two parity nodes based on invariant subspace technique. Codes constructed in their framework not only contain some best known codes as special cases, but also include some new codes with good properties such as the optimal access property and the optimal update property. In addition, to the best of their knowledge, two of the new codes have the largest number of systematic nodes with the optimal update property for given store capacity of an individual node.
