PowerHA 7.4 HA 4.1.1 with PTF SI71362 SI72362 and 7.2 HA 3.3 with PTF SI71439 SI72439 brings several enhancements to the portfolio including:
...
For synchronous solutions in a PowerHA environment, such as Metro Mirror or synchronous geographic mirroring, the recovery point objective is 0. However, synchronous solutions are limited in distance with maximum distances of around 300 kilometers. PowerHA enables replication to span the globe with asynchronous replication solutions such as Global Mirror; the trade-off for greater distances is a larger RPO.
With HA version 7.2 HA 3.3 and 7.4 HA 4.1.1 PowerHA now provides real-time RPO information on the display session screens for IBM Spectrum Virtualize (SVC) based and IBM Copy Services Manager for DS8000 (CSM) based replication. This enables users to know their RPO.
...
The Display Session screens in PowerHA display information related to replication and independent ASP status. These screens have been re-designed to take advantage of 132-column displays when available and provide a clearer indication of replication status with an arrow.
