Chapter VII. iSCSI PDU Offload Target

Chelsio T5/T4 Unified Wire For Linux Page 101

1.3. Software Requirements

chiscsi_base.ko is iSCSI non-offload target mode driver and chiscsi_t4.ko is iSCSI PDU

offload target mode driver.

cxgb4, toecore, t4_tom and chiscsi_base modules are required by chiscsi_t4.ko module to

work in offloaded mode. Whereas in iscsi non-offloaded target (NIC) mode, only cxgb4 is

needed by chiscsi_base.ko module.

1.3.1. Linux Requirements

Currently the iSCSI PDU Offload Target software is available for the following versions:

Redhat Enterprise Linux 5 update 9 kernel (RHEL5.9), 2.6.18-348.el5*

Redhat Enterprise Linux 5 update 10 kernel (RHEL5.10), 2.6.18-371.el5*

Redhat Enterprise Linux 6 update 4 kernel (RHEL6.4), 2.6.32-358.el6

Redhat Enterprise Linux 6 update 5 kernel (RHEL6.5), 2.6.32-431.el6*

Suse Linux Enterprise Server 11 SP1 kernel (SLES11SP1), 2.6.32.12-0.7

Suse Linux Enterprise Server 11 SP2 kernel (SLES11SP2), 3.0.13-0.27*

Suse Linux Enterprise Server 11 SP3 kernel (SLES11SP3), 3.0.76-0.11

Ubuntu 12.04, 3.2.0-23*

Kernel.org linux-3.4*

Kernel.org linux-3.6

Kernel.org linux-3.7*

Other kernel versions have not been tested and are not guaranteed to work.

*Limited QA performed

1.3.2. Requirements for Installing the iSCSI Software

When installing the iSCSI software, it is required that the system have Linux kernel source or its

headers installed in order to compile the iSCSI software as a kernel module. The source tree

may be only header files, as for RHEL5 as an example, or a complete tree. The source tree

needs to be configured and the header files need to be compiled. Additionally, the Linux kernel

must be configured to use modules.

License Key Requirement

A production/evaluation license file,is required for each copy of the Chelsio iSCSI PDU Offload

Target software installed. The license is tied to the selected Chelsio NIC present in the system.

The license file will be generated depending on your requirement for a Chelsio iSCSI Target.

Note

chiscsi_t4 compiles on all Kernel.org Linux Kernels 2.6.18+ Kernels, but only

tested and guaranteed to work with above mentioned OSes.
