Implement a storage mapper for IBM FlashSystem

IBM guarantees all FlashSystem versions should have a compatible API, certainly for the basic API calls for map, unmap,  getVolume . 

IBM allocated a virtualized OCP and vsphere instance connected to a FlashSystem and available over a VPN connection, without time limitations.

The VPN access is granted to bodnopoz@redhat.com tshefi@redhat.com rh-ee-obengali and rgolan1@redhat.com
