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.

2. Hardware Installation
Follow the steps to install Chelsio Adapter in your system:
1. Shutdown and 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 10Gb 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 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

Chapter I. Chelsio Unified Wire
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.
Note
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.

1. Introduction
Chelsio’s T5 and T4 series of Unified Wire Adapters provide extensive support for NIC
operation, including all stateless offload mechanisms for both IPv4 and IPv6 (IP, TCP and UDP
checksum offload, LSO - Large Send Offload aka TSO - TCP Segmentation Offload, and assist
mechanisms for accelerating LRO - Large Receive Offload).
A high performance fully offloaded and fully featured TCP/IP stack meets or exceeds software
implementations in RFC compliance. Chelsio’s T5/T4 engine provides unparalleled performance
through a specialized data flow processor implementation and a host of features designed for
high throughput and low latency in demanding conditions and networking environments, using
standard size Ethernet frames.
TCP offload is fully implemented in the hardware, thus freeing the CPU from TCP/IP overhead.
The freed CPU can be used for any computing needs. The TCP offload in turn removes network
bottlenecks and enables applications to take full advantage of the networking capabilities.

Chapter III. iSCSI PDU Offload Initiator
1. Introduction
The Chelsio T5 and T4 series adapters support iSCSI acceleration and iSCSI Direct Data
Placement (DDP) where the hardware handles the expensive byte touching operations, such as
CRC computation and verification, and direct DMA to the final host memory destination:
iSCSI PDU digest generation and verification
On transmitting, Chelsio h/w computes and inserts the Header and Data digest into the
PDUs. On receiving, Chelsio h/w computes and verifies the Header and Data digest of the
PDUs.
Direct Data Placement (DDP)
Chelsio h/w can directly place the iSCSI Data-In or Data-Out PDU's payload into pre-posted
final destination host-memory buffers based on the Initiator Task Tag (ITT) in Data-In or
Target Task Tag (TTT) in Data-Out PDUs.
PDU Transmit and Recovery
On transmitting, Chelsio h/w accepts the complete PDU (header + data) from the host
driver, computes and inserts the digests, decomposes the PDU into multiple TCP segments
if necessary, and transmit all the TCP segments onto the wire. It handles TCP
retransmission if needed.
On receiving, Chelsio h/w recovers the iSCSI PDU by reassembling TCP segments,
separating the header and data, calculating and verifying the digests, then forwarding the
header to the host. The payload data, if possible, will be directly placed into the pre-posted
host DDP buffer. Otherwise, the payload data will be sent to the host too.
The cxgb4i driver interfaces with open-iSCSI initiator and provides the iSCSI acceleration
through Chelsio hardware wherever applicable.

If loading of driver fails, then kill iscsid, unload all open iSCSI modules and
related/dependent modules (like multipath, bnx2i etc). Finally, load the cxgb4i
driver.
Note
2. Software/Driver Loading
The driver must be loaded by the root user. Any attempt to load the driver as a regular user will
fail.
Run the following command to load the driver:
[root@host]# modprobe cxgb4i
Chelsio T5/T4 Unified Wire For XenServer Page 23
Chapter III. iSCSI PDU Offload Initiator
3. Software/Driver Unloading

[root@host]# rmmod cxgb4i
[root@host]# rmmod libcxgbi
Chelsio T5/T4 Unified Wire For XenServer Page 24
Chapter III. iSCSI PDU Offload Initiator
Always take a backup of iscsid.conf file before installing Chelsio Unified
Wire Package.
Important
4. Software/Driver Configuration and Fine-tuning
4.1. Accelerating open-iSCSI Initiator
The following steps need to be taken to accelerate the open-iSCSI initiator:
4.1.1. Configuring iscsid.conf file
Edit the iscsi/iscsid.conf file and change the setting for MaxRecvDataSegmentLength:
node.conn[0].iscsi.MaxRecvDataSegmentLength = 8192
The login would fail for a normal session if MaxRecvDataSegmentLength is too big. A error
message in the format of ERR! MaxRecvSegmentLength <X> too big. Need to be <=
<Y>. would be logged to dmesg.
4.1.2. Configuring interface (iface) file
Create an interface file located under iface directory for the new transport class cxgb4i in the
following format:
iface.iscsi_ifacename = <iface file name>
iface.hwaddress = <MAC address>
iface.transport_name = cxgb4i
iface.net_ifacename = <ethX>
iface.ipaddress = <iscsi ip address>
E.g.:-
iface.iscsi_ifacename = cxgb4i.00:07:43:04:5b:da
iface.hwaddress = 00:07:43:04:5b:da
iface.transport_name = cxgb4i
iface.net_ifacename = eth3
iface.ipaddress = 102.2.2.137
Chelsio T5/T4 Unified Wire For XenServer Page 25
Chapter III. iSCSI PDU Offload Initiator
if iscsid is already running, then kill the service and start it as shown above
after installing the Chelsio Unified Wire package.
Note
i. The interface file needs to be created in /etc/iscsi/iscsid.conf.
ii. If iface.ipaddress is specified, it needs to be either the same as the
ethX's IP address or an address on the same subnet. Make sure the IP
address is unique in the network.
Note
Alternatively, you can create the file automatically by executing the following command:
[root@host]# iscsiadm -m iface
Here,
iface.iscsi_ifacename denotes the name of interface file in /etc/iscsi/ifaces/.
iface.hwaddress denotes the MAC address of the Chelsio interface via which iSCSI traffic
will be running.
iface.transport_name denotes the transport name, which is cxgb4i.
iface.net_ifacename denotes the Chelsio interface via which iSCSI traffic will be running.
iface.ipaddress denotes the IP address which is assigned to the interface.
4.1.3. Discovery and Login
i. Starting iSCSI Daemon
Start Daemon from /sbin by using the following command:
[root@host]# iscsid -f -d 3
ii. Discovering iSCSI Targets
To discovery an iSCSI target execute a command in the following format:
iscsiadm -m discovery -t st -p <target ip address>:<target port no> -I <cxgb4i iface file
name>
Chelsio T5/T4 Unified Wire For XenServer Page 26
Chapter III. iSCSI PDU Offload Initiator
Other options can be found by typing iscsiadm --help
Note
E.g.:-
[root@host]# iscsiadm -m discovery -t st -p 102.2.2.155:3260 -I
cxgb4i.00:07:43:04:5b:da
iii. Logging into an iSCSI Target
Log into an iSCSI target using the following format:
iscsiadm -m node -T <iqn name of target> -p <target ip address>:<target port no> -I
<cxgb4i iface file name> -l
E.g.:-
[root@host]# iscsiadm -m node -T iqn.2004-05.com.chelsio.target1 -p
102.2.2.155:3260,1 -I cxgb4i.00:07:43:04:5b:da -l
iv. Logging out from an iSCSI Target
Log out from an iSCSI Target by executing a command in the following format:
iscsiadm -m node -T <iqn name of target> -p <target ip address>:<target port no> -I
<cxgb4i iface file name> -u
E.g.:-
[root@host]# iscsiadm -m node -T iqn.2004-05.com.chelsio.target1 -p
102.2.2.155:3260,1 -I cxgb4i.00:07:43:04:5b:da -u
4.2. Auto login from cxgb4i initiator at OS bootup
For iSCSI auto login (via cxgb4i) to work on OS startup, please add the following line to
start() in /etc/rc.d/init.d/iscsid file on RHEL:
modprobe -q cxgb4i
Chelsio T5/T4 Unified Wire For XenServer Page 27
Chapter III. iSCSI PDU Offload Initiator
E.g.:-
force_start() {
echo -n $"Starting $prog: "
modprobe -q iscsi_tcpmodprobe -q ib_iser
modprobe -q cxgb4i
modprobe -q cxgb3i
modprobe -q bnx2i
modprobe -q be2iscsi
daemon brcm_iscsiuio
