1.Introduction
Thank you for choosing Chelsio T5/T4 Unified Wire adapters. These high speed, single chip,
single firmware cards provide enterprises and data centers with high performance solutions for
various Network and Storage related requirements.
The Terminator 5 (T5) is Chelsio’s next generation of highly integrated, hyper-virtualized
40/10GbE controllers. The T5 is built around a programmable protocol-processing engine, with
full offload of a complete Unified Wire solution comprising NIC, TOE, iWARP RDMA, ISCSI,
FCoE and NAT support. It scales true 40Gb line rate operation from a single TCP connection to
thousands of connections, and allows simultaneous low latency and high bandwidth operation
thanks to multiple physical channels through the ASIC.
The T4 adapters can fully offload TCP, UDP, iSCSI, iWARP and FCoE over a single Unified
Wire. The adapters also fully support SR-IOV, EVB/VNTag, DCB, Traffic Management and
Filtering.
Ideal for all data, storage and high performance clustering applications, the T5/T4 Adapters
enable a unified fabric over a single wire by simultaneously running all unmodified IP sockets,
Fibre Channel and InfiniBand applications over Ethernet at line rate.
Designed for deployment in virtualized data centers, cloud service installations and high
performance computing environments, Chelsio T5/T4 adapters bring a new level of performance
metrics and functional capabilities to the computer networking industry.
Chelsio Unified Wire software comes in two formats: Source code and RPM package forms.
Installing from source requires compiling the package to generate the necessary binaries. You
can choose this method when you are using a custom-built kernel. You can also install the
package using the interactive GUI installer. In other cases, download the RPM package specific
to your operating system and follow the steps mentioned to install the package. Please note that
the OFED software required to install Chelsio iWARP driver comes bundled in both source as
well as RPM packages.
This document describes the installation, use and maintenance of the software and its
various components.
1.1. Features
The Chelsio Unified Wire Package uses a single command to install various drivers and utilities.
It consists of the following software:
Network (NIC/TOE)
Virtual Function Network (vNIC)
iWARP (RDMA)

libs: This directory is for libraries required to install the WD-TOE, WD-UDP and iWARP
drivers. The libibverbs library has implementation of RDMA verbs which will be used by
iWARP applications for data transfers. The librdmacm library works as an RDMA connection
manager. The libcxgb4 library works as an interface between the above mentioned generic
libraries and Chelsio iWARP driver. The libcxgb4_sock library is a LD_PRELOAD-able
library that accelerates UDP Socket communications transparently and without
recompilation of the user application.
Makefile: The Makefile for building and installing from the source.
sample_machinefile: Sample file used during iWARP installation on cluster nodes.
scripts: Support scripts used by the Unified Wire Installer.

benchmarks: This directory contains various benchmarking tools to measure
throughput and latency of various networks.
cop: The cop tool compiles offload policies into a simple program form that can be
loaded into the kernel and interpreted. These offload policies are used to determine
the settings to be used for various connections. The connections to which the
settings are applied are based on matching filter specifications. Please find more
details on this tool in its manual page (run man cop command).
cxgbtool: The cxgbtool queries or sets various aspects of Chelsio network
interface cards. It complements standard tools used to configure network settings
and provides functionality not available through such tools. Please find more details
on this tool in its manual page (run man cxgbtool command).
rdma_tools: This directory contains iWARP benchmarking tools.
sniffer: This directory contains sniffer tracing and filtering libraries. See WD Sniffing
and Tracing chapter for more information.
um: This directory contains Unified Wire Manager RPMs for different distributions
and Management Station configuration files.
chsetup: The chsetup tool loads NIC,TOE and iWARP drivers, and creates WD-
UDP configuration file.
chstatus: This utility provides status information on any Chelsio NIC in the system.
To use cxbtool for FCoE Initiator driver, use [root@host]# cxgbtool stor –h
Note

2.Hardware Installation
Follow these steps to install Chelsio Adapter in your system:
1. Shutdown/power off your system.
2. Power off all remaining peripherals attached to your system.
3. Unpack the Chelsio adapter and place it on an anti-static surface.
4. Remove the system case cover according to the system manufacturer’s instructions.
5. Remove the PCI filler plate from the slot where you will install the Ethernet adapter.
6. For maximum performance, it is highly recommended to install the adapter into a PCIE x8
slot.
7. Holding the Chelsio adapter by the edges, align the edge connector with the PCI connector
on the motherboard. Apply even pressure on both edges until the card is firmly seated. It
may be necessary to remove the SFP (transceiver) modules prior to inserting the adapter.
8. Secure the Chelsio adapter with a screw, or other securing mechanism, as described by the
system manufacturer’s instructions. Replace the case cover.
9. After securing the card, ensure that the card is still fully seated in the PCIE x8 slot as
sometimes the process of securing the card causes the card to become unseated.
10. Connect a fiber cable, multi-mode for short range (SR) optics or single-mode for long range
(LR) optics, to the 40/10Gb Ethernet adapter or regular Ethernet cable for the 1Gb Ethernet
adapter.
11. Power on your system.
12. Verify if the adapter was installed successfully by using the lspci command
a. For T5 adapters :
[root@host]# lspci |grep -i Chelsio

For Chelsio T5/T4 adapters, the physical functions are currently assigned as:
Physical functions 0 - 3: for the SR-IOV functions of the adapter
Physical function 4: for all NIC functions of the adapter
Physical function 5: for iSCSI
Physical function 6: for FCoE
Physical function 7: Currently not assigned
Once Unified Wire package is installed and loaded, examine the output of dmesg to see if the
card is discovered.

The above outputs indicate the hardware configuration of the adapters as well as the Serial
numbers. As observed by the x8, the card is properly installed in an x8 slot on the machine and
using MSI-X interrupts.
Network device names for Chelsio’s physical ports are assigned using the
following convention: the port farthest from the motherboard will appear as the
first network interface. However, for T5 40G and T420-BT adapters, the
association of physical Ethernet ports and their corresponding network device
names is opposite. For these adapters, the port nearest to the motherboard will
appear as the first network interface.

3.Software/Driver Installation
There are two main methods to install the Chelsio Unified Wire package: from source and RPM.
If you decide to use source, you can install the package using CLI or GUI mode.
If you decide to use RPM, you can install the package using Menu or CLI mode.
Irrespective of the method chosen for installation, the machine needs to be rebooted for
changes to take effect.
The following table describes the various configuration tuning options available during
installation and drivers/software installed with each option by default:
