Supported Operating Systems and OFED
Table 6-1 shows the operating system support for RoCE v1/v2 and OFED:
Planning
As you prepare to implement RoCE, consider the following limitations:
 If you are using the in-box OFED, the operating system should be the same
on the server and client systems. Some of the applications may work
between different operating systems, but there is no guarantee. This is an
OFED limitation.
 For OFED applications (most often perftest applications), server and client
applications should use the same options and values. For example,
problems can arise if the operating system and the perftest application have
different OFED versions. To confirm the perftest OFED version, type the
following command:
# ib_send_bw --version
 qedr and libqedr RPM packages are required for in-box OFED.
 OFED/RDMA applications that depend on libibverbs also require the QLogic
RDMA user space library, libqedr. libqedr can be installed using libqedr RPM
or source packages
 Mounting NFS over RDMA may take more time than normal on RHEL 7.0,
7.1, and SLES 12.
 RoCE supports only little endian.
 RoCE will not work over a VF in an SR-IOV environment.
 RoCE is enabled by default for both V1 and V2.
