  An explicit construction of systematic MDS codes, called HashTag+ codes, with
arbitrary sub-packetization level for all-node repair is proposed. It is shown
that even for small sub-packetization levels, HashTag+ codes achieve the
optimal MSR point for repair of any parity node, while the repair bandwidth for
a single systematic node depends on the sub-packetization level. Compared to
other codes in the literature, HashTag+ codes provide from 20% to 40% savings
in the average amount of data accessed and transferred during repair.
