This page answers Frequently Asked Questions you may have with regard to licensing Datera, Inc. software, such as LinuxIO, targetcli, or Core-iSCSI.


What license is Datera software released under?

LIO is released under the GNU General Public License, version 2 (GPLv2), and targetcli is released under the Apache License, version 2.0 (Apache License). Essentially, this means that you get the full source code , and you can distribute and modify it, provided that for the GPL parts you ship all modifications as well.

Will our licensing terms be changed in the future?

We are not currently planning to do so, but it doesn't really matter. Any code that was once released under the GNU General Public License, version 2 (GPLv2) cannot be "closed" again. The license that Datera has granted you with the GPL is perpetual and cannot be taken back. Even if Datera were to change the license again, this could only affect future versions, and anybody would still be permitted to redistribute our existing code under the terms of the GPL.

Which guidelines apply to the use of the name Datera, Inc.?

The term Datera Systems has been registered by Datera as a trademark in a number of countries. It may be freely used together with the products available from this web site. However, if you choose to ship custom binaries and/or source code revisions of the product, Datera reserves the right to deny use of the trademark Datera Systems. This might seem rather strict but we believe that it is important to avoid any kind of confusion arising from multiple versions of the same product coming from different sources.
