Tomo,
Looking at drivers/scsi/Kconfig there does seem to be
some connection:

config SCSI_IBMVSCSI
        tristate "IBM Virtual SCSI support"
        depends on PPC_PSERIES || PPC_ISERIES
        help
          This is the IBM POWER Virtual SCSI Client
...
config SCSI_IBMVSCSIS
        tristate "IBM Virtual SCSI Server support"
        depends on PPC_PSERIES && SCSI_TGT && SCSI_SRP
        help
          This is the SRP target driver for IBM pSeries virtual environments.
...


When I see SRP than I presume infiniband is involved.

Perhaps you might elaborate.
