Can I generate a triple-redundant license for Xilinx products?
Does the Xilinx software licensing support three redundant servers?
Yes, if you are the Xilinx FLEX Administrator or a user with floating license privileges, you can generate a triple-redundant license.
To generate a triple-redundant server license for a floating license, the Xilinx license account or floating license administrator will need to select Yes on the right of the "Redundant Server?" line. This enables the administrator to select or add hostID information for a primary and two backup servers.
In a redundant license server system, three machines are identified as license servers, but only one is the master that can issue licenses. Each machine has an identical copy of the license file with three SERVER lines, one for each SERVER identified.
In the XILINXD_LICENSE_FILE environment variable, the three servers are separated with comas.
As an alternative to redundant license servers, you might prefer to use a license-file list. When using a license-file list, split the licenses into multiple files and identify the locations in the XILINXD_LICENSE_FILE environment variable separated on UNIX by a colon (:), and on Windows by a semicolon (;).
