Blog Post created by Nick Dyer Employee on Sep 1, 2016

Back in February/March 2016, Nimble embarked on one of it's biggest feature updates in history - NimbleOS 3, with the first Release Candidates being made available to specific whitelisted systems.


Throughout the last 4-6 months the code has been field-tested, refined and burnt in - and has achieved >99.999% availability in production use from the Infosight data recorded from these systems. Therefore NimbleOS 3 is now officially marked as Generally Available (GA) for ALL Adaptive and All Flash Arrays - and is available to download through your array GUI browser NOW!


Be sure to check the Release Notes on Infosight for the requisites and known issues.


Also ensure that you update Nimble Connection Manager for VMware and the Windows Toolkit to Version 3 BEFORE upgrading your array OS, as well as upgrading add-on items such as the VMware SRA for Site Recovery Manager.


Here's an SE-led blog series on some of the new features within NimbleOS 3, and here's the Concepts Guide for the new OS.
