We are about to migrate our VMWare estate to Symmetrix VMAX storage (Eng 5875 SYMAPI 7.2).  It runs on 48 blades each with 2 HBAs, that is 96 wwpns in total. We intend to use a single Storage Group and initially thought we would define one initiator group for the whole estate with a cascaded initiator group for each blade, but the VMAX only allows 32 cascaded initiator groups. We think we have 2 options.

A.  Single mask view with an initiator group for the estate containing 3 cascaded initiator groups each containing 32 wwpns (16 blades).
B.  A separate mask view and initiator group for each Blade.

We prefer option A but would welcome posts from anyone else who has Autoprovisoned a large VMWare estate from a VMAX or can provide links to relevant guidelines.
