Supported iWARP Applications
Linux-supported RDMA applications for iWARP include the following:
ibv_devinfo, ib_devices
ib_send_bw/lat, ib_write_bw/lat, ib_read_bw/lat, ib_atomic_bw/lat
For iWARP, all applications must use the RDMA communication manager
(rdma_cm) using the
-R
option.
rdma_server, rdma_client
rdma_xserver, rdma_xclient
rping
NFS over RDMA (NFSoRDMA)
iSER (for details, see
NVMe-oF (for details, see
Chapter 12 NVMe-oF Configuration with RDMA
Running Perftest for iWARP
All perftest tools are supported over the iWARP transport type. You must run the
tools using RDMA connection manager (with the
-R
option).
Example:
1.
On one server, issue the following command (using the second port in this
example):
#
ib_send_bw -d qedr1 -F -R
2.
On one client, issue the following command (using the second port in this
example):
[root@localhost ~]#
ib_send_bw -d qedr1 -F -R 192.168.11.3
