Theo, zHyperlink write functionality should work in a Metro Mirror environment with appropriate maintenance, but you also need to activate zHyperwrite to have your DB2 log writes done simultaneously to the primary and secondary volumes. We have been told by IBM that zHyperlink write functionality will not work in a Metro Global Mirror environment. There is no issue with zHyperlink read functionality and we are seeing response times consistent with IBM documentation in the neighborhood of 25 microseconds.

Hi, How does synchronous replication of DB2 data affect the effectiveness of zHyperlink? The storage array and the mainframe is within the 150m distance, however our DR site is way beyond this distance.
