Compression acceleration

zEnterprise Data Compression (zEDC) for z/OS V2.1, running on zEC12 and zBC12 with the zEDC Express feature, is designed to support a new data compression function designed for efficient, low-latency compression and improved cross platform communications.

The IBM Washington Systems Center (WSC) has created a sizing tool for use with zEDC, the IBM System z Batch Network Analyzer (zBNA). zBNA is a free, as-is tool that analyzes batch windows using SMF records to help determine if you have files that are candidates for zEDC. It can also help estimate the number of H/W features you will need.
