I just read a tweet by @PatrickLownds saying that the Service Pack for ProLiant 2016.10.0 is now available. This means Windows Server 2016 is now officially supported. I have been able to try out this version for some time now and have not run into any major problems (yet). Please write a comment if you run into anything significant.
The blog I wrote about Workaround to enable clusters2d with some storage controllers actually depended on this SSP, changing the RAID bustype to SAS.
This SSP is the last one that supports the ProLiant G6 series, but you can forget about support for Windows Server 2016.
Since a few years, these SSP’s can only be downloaded if you have an active warranty or HP support agreement. I can’t say I’m happy with this change and hopefully one day HPE comes back on this decision.
