This writeup is taken from the ChelsioT4 UnifiedWire Linux UserGuide (pdf) and trimmed for installation on RHEL5.4 or CentOS 5.4. But it should apply for other RHEL / CentOS versions

Installing Chelsio Software

# tar -zxvf ChelsioUwire-

3. Navigate to “ChelsioUwire-x.x.x.x” directory. Run the following command

Compiling and Loading of iWARP (RDMA) driver

To use the iWARP functionality with Chelsio adapters, user needs to   install the iWARP drivers as well as the libcxgb4, libibverbs, and librdmacm   libraries. Chelsio provides the iWARP drivers and libcxgb4 library as part of the driver package. The other libraries are provided as part of the Open   Fabrics Enterprise Distribution (OFED) package.

# modprobe cxgb4
# modprobe iw_cxgb4
# modprobe rdma_ucm
# echo 1 >/sys/module/iw_cxgb4/parameters/peer2peer

Testing connectivity with ping and rping.

On the Client Server,

# rping -c –Vv -C10 -a server_ip_addr -p 9999
