Need more than 16 WWPN Support Per WWPN

See this idea on ideas.ibm.com

The customer needs to place an Emc VMax3 behind the SVC. The VMax has 128 WWPN and SVC only supports 16..
Customer: "One of my concerns with SVC in front of VMAX storage is the limited number of paths that are supported (16). THIS IS NOT A BANDWIDTH ISSUE.

In a fully configured VMAX there are 64 Front End (FA) ports. There are actually 128 but we only use 64. Each of the 64 ports has a front-end processor that handles the I/O requests that come in to that port. Each processor can handle a certain number of IOPS. In order to get maximum performance out of a VMAX you have to use all the FA ports - think Horizontal Scaling, or Scale-Out."

    Due to processing by IBM, this request was reassigned to have the following updated attributes:
    Brand - Servers and Systems Software
    Product family - Storage
    Product - IBM System Storage SAN Volume Controller (SVC) / Spectrum Virtualize

    For recording keeping, the previous attributes were:
    Brand - Tivoli
    Product family - Storage
    Product - IBM System Storage SAN Volume Controller (SVC) / Spectrum Virtualize

    We were in the same scenario, it is a complete waste of FA ports for VMAX(s) and other systems including DS with this limitation
