1. Dates are subject to change

Mitigation:
Referring to the recommendations made by third-party suppliers, Fujitsu strongly advises all customers to update affected products. Updates are provided through an updated version of the BIOS and the necessary patches for the dedicated operating system. Under some circumstances, enabling these updates may affect performance. The actual performance impact will depend on multiple factors, such as the specific CPU generation in your physical host and the system load (used application). Fujitsu recommends that customers assess the performance impact for their system environment and make necessary adjustments.

The security of our products and our customers’ data is number one priority for Fujitsu. We are continuing to work with our partners in the industry to minimize any potential performance impact.

Fujitsu highly recommends customers to ensure that systems are physically secured where possible, and follow good security practices to ensure that only authorized personnel have access to devices.

Recommended steps:

  1. It is necessary to update the BIOS
  2. Consult the list of affected Fujitsu systems for the timing of BIOS availability.
  3. To download the respective updates for your system, please go to the Fujitsu Support page http://support.fujitsupc.com/CS/Portal/support.do?srch=DOWNLOADS and perform the following steps:
