Planning and Monitoring z/OS Global Mirror (XRC):
Resource Management Facility (RMF) in z/OS records a wealth of statistics reflecting the usage of Disk Subsystems. These statistics can be used effectively to plan and monitor a z/OS Global Mirror configuration, provided one has access to a tool such as IntelliMagic Vision that can consolidate the RMF data by disk subsystem, aggregate statistics by user-defined groups of volumes and compute supplemental information, such as Write Megabytes.

IntelliMagic Vision can drastically improve disk subsystem performance visibility and with that make the performance analyst more effective in planning and monitoring a z/OS Global Mirror configuration. IntelliMagic Vision includes specialized XRC reports on SDM's and Readers, for example, and can also read GEOXPARM files.
