SharePoint Server 2016 Zero Downtime – The Real World

So what is SharePoint Server 2016 Zero Downtime in the real world? With the release of the first SharePoint Server 2016 patch, we can officially say — it’s a bit less than zero. Zero Downtime means exactly one thing:

The farm is never fully taken offline.

What does that mean for individual farm members? They require service restarts and/or reboots. They’ll be offline.

This is why Zero Downtime requires High Availability of all services [you want to keep available]. This is certainly an improvement over previous versions of SharePoint where you had the inevitable downtime when running the Config Wizard as the database schema are updated, but for those not running highly available farms, expect downtime for your services and plan accordingly.

I would continue to encourage you to look at Russ Maxwell’s patch script, replacing all instances of “OSearch15” with “OSearch16”. Like SharePoint Server 2013, your patching process will be rather slow without a similar script in place.

You can test “Zero Downtime” by installing KB2920721 today!

  1. Trevor,

    according to this article “http://blogs.technet.com/b/pla/archive/2016/03/10/zero-downtime-patching-in-sharepoint-server-2016.aspx” and the last comment on it the only change in 2016 is the ability to keep a farm up (content db) in read/write mode during the build to build upgrade inside the Config Wizard. So are you confirming this? or there is more than that in the 2016 release?!
