    Before the announcement of zEDC hardware compression, DFSMShsm was already able to compress migration and backup data using its own compaction (based on Huffman frequency Encoding algorithm) on disk and tape data. This Redpaper shares a sample implementation of zEDC hardware compression performed in a controlled test environment and looks at the impact of zEDC compression up to Migration Level 1.
