Chapter VII. iSCSI PDU Offload Target
Chelsio T5/T4 Unified Wire For Linux Page 102
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 7 kernel (RHEL5.7), 2.6.18-274.el5 *
Redhat Enterprise Linux 5 update 8 kernel (RHEL5.8), 2.6.18-308.el5 *
Redhat Enterprise Linux 6 update 3 kernel (RHEL6.3), 2.6.32-279.el6*
Redhat Enterprise Linux 6 update 4 kernel (RHEL6.4), 2.6.32-358.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
Kernel.org linux-2.6.35*
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
The iSCSI PDU offload software provided in the Unified Wire package is an evaluation copy
fully functional for a period of 30-days. After the trial period, a license key file is required to
continue using the software. To obtain the key file a binary program called “chinfotool” must
be run on the host system where the iSCSI software is to be installed. That program generates
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.
