They are not available for public download as we encourage everyone to use the latest versions. If you need them for some compliance or change management reasons, you can open a case and a support engineer will give you a temporary link for download.

Btw, please note that AOS 5.5.X will become unsupported in September 2020, which is a bit more than 1 month from now.

Sergei thanks for your fast reply. Please tell me, can I open the case as Nutanix partner to get that download link without the serial number?

I am trying to install on some older servers and I need that specific version of Foundation.

Can I send the mail request to support@nutanix.com ?

That’s not possible to open a case without a S/N. What is the server model that you are going to use? Maybe i can check if there is a newer version of Foundation that can be downloaded that supports that model.

Server is Huawei 2288H V5 25 SFF.

Well, the Huawei servers are not in the list of our supported hardware, so you will likely be on your own if there are any issues with it. I haven’t seen any limitations in the newer Foundation versions. Have you tried using the latest Foundation? Is it failing with it?
