Increase limit for z/VM VSwitch HiperSocket Bridge Port connectivity to LPAR

Customer environment uses VSWITCH with a hipersocket bridge and OSA to use a single network that spans CECs. In z/VM 720 the maximum is four LPARs per CEC that can connect to the hipersocket bridge. At DND each CEC has between eight to twelve zVM LPARs. This means that the fifth and higher LPARs cannot use the hipersocket and will revert to using the OSA intra CEC and inter CEC. The OSAs on a hipersocket bridge VSWITCH are intended to connect between CECs so the same network range can span multiple CECs. Intra CEC network traffic is intended for the hipersocket. We would like to see the maximum of four expanded to sixteen LPARs per CEC connecting to a hipersocket bridge. Given that a VSWITCH on to each LPAR is using a VSWITCH defined as hiperbridge with OSAs on 800 and 900 with hipersocket on C40. PLEASE SEE ATTACHED FILE THAT INCLUDES THE DIAGRAM to fully describes the request.

    This support also requires a corresponding HiperSockets firmware enhancement. The outlook for delivering this support is difficult to predict.
