ExaLINK Fusion : Understanding Support, Licensing and FPGA Modes

License files

Each ExaLINK Fusion device requires a license file from Exablaze. The license file enables usage of the Fusion, firmware upgrades as well as any additional features which may have been purchased.

Full details on ExaLINK Fusion licenses can be found at: https://fusion.exablaze.com/about/license/

End of support date

A support contract is included with all Fusion purchases that provides access to Exablaze engineering and support staff, hardware warranty and access to firmware upgrades as they are released.

Each ExaLINK Fusion device has the end of support date as part of its license file. The end of support date is not an expiry date.

After the end of support date:

  • You may continue to install and use any firmware released before that date, with no restrictions or time limits.
  • You will not have access to any new firmware updates released after that date
  • You will no longer have access to support from Exablaze staff
To extend the support of your Fusion device(s) please contact sales@exablaze.com

Time-limited evaluation licenses

ExaLINK Fusion devices provided to customers for evaluation will have a license file with an expiry date. Exablaze may also provide time-limited licenses for a device that has been purchased, for the purpose of evaluating features that are licensed separately.

The expiry date field in a license is only used for enforcing the evaluation period and limiting the use of evaluation devices. ExaLINK Fusion devices that have been purchased have a license with no expiry date.

Details on evaluation license settings can be found at: https://fusion.exablaze.com/about/license/#evaluation-licenses 

FPGA modes

Each customer's ExaLINK Fusion device will come loaded with Fusion firmware.

The Fusion firmware logic can allow any installed FPGA module in the Fusion to run in several different modes. These FPGA running modes are:

  • "mux" mode - which allows the creation of mux objects only
  • "fastmux" mode - which allows the creation of mux objects in raw mode only
  • "switch" mode - which allows the creation of mux objects and potentially switch objects

Any customer that has an enabled Fusion device with firmware 1.6.0 onward can set that devices FPGA running mode  to "mux",  "fastmux" or "switch" mode to create mux objects.

If additionally the Fusion device has a license with the 'switch' feature enabled the customer can also create switch objects when running in "switch" mode.
