Regarding existing test software: the SRP test software is a thorough test =
of
the Linux block layer, SCSI core, dm-mpath driver, dm core, SRP initiator a=
nd
target drivers and also of the asynchronous I/O subsystem. This test suite
includes experimental support for the NVMeOF drivers. This test suite suppo=
rts
the rdma_rxe driver which means that an Ethernet adapter is sufficient to r=
un
these tests.

Note: the focus of this test suite is the regular I/O path and device remov=
al.
This test suite neither replaces the libiscsi tests nor xfstests.
