Ability to configure PB-HA and PB-R between the same two storages.

Here in Brazil, we have some customers who have only two storages and they ask us (IBM) for the ability to configure PB-HA and PB-R between these two storages.

Today, we only support PB-R or PB-HA between the same storages, to support PB-R and PB-HA we need three storages. I do not talking about 3-Site Replication for PB-HA.

The request is to support PB-R and PB-HA between only to storages at same time, examples:
Storage1(Serial XYZ) -> PB-R -> Storage2(Serial ZZZ)
Storage1(Serial XYZ) -> PB-HA -> Storage2(Serial ZZZ)
or
Storage1(Serial XYZ) <- PB-R <- Storage2(Serial ZZZ)
Storage1(Serial XYZ) -> PB-HA -> Storage2(Serial ZZZ)
or
Storage1(Serial XYZ) <- PB-R <- Storage2(Serial ZZZ)
Storage1(Serial XYZ) -> PB-HA -> Storage2(Serial ZZZ)
Storage1(Serial XYZ) <- PB-HA <- Storage2(Serial ZZZ)
or
Storage1(Serial XYZ) -> PB-R -> Storage2(Serial ZZZ)
Storage1(Serial XYZ) <- PB-R <- Storage2(Serial ZZZ)
Storage1(Serial XYZ) -> PB-HA -> Storage2(Serial ZZZ)
Storage1(Serial XYZ) <- PB-HA <- Storage2(Serial ZZZ)

    We have request where AppA/Partition1/Tier1 requires HA (imagine Mirroring or HyperSwap) , Whereas AppB/Partition2/Tier2 just requires a DR copy in next building (be it like a MM or GM , or now PBR). This is a desired feature. Thank you for consideration.

    bot all volumes are equal, especially in bigger env at CSI/MSP, customers only get what they pay for, therefor the multiple choices is needed.
    PBHA+DR
    PBR-->DR
    PBHA (no 3rd site)
    Single site

    all between same 3 boxes, would make the options for CSI/MSP to make customers pay for what type of resillience they want to pay for.

    Thank you for submitting this Idea. Can you provide more information about the use case for having both Async and HA configured between the same two systems?


    Thanks,
