NimbleOS 3 is now Generally Available (GA)!


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.

NOTE: VSS integration with hosts leveraging Nimble Windows Toolkit (NWT) 2.1 and earlier will not work with NimbleOS 3.x.

Will Nimble be updating their download source definitions for VMware Update Manager via the following URLs? They still list Nimble Connection Manager for VMware 2.3.1.





UPDATE: Overnight the generic NCM links have now switched from NCM 2 to NCM 3.


Perfect, thanks for the explanation and interim workaround Nick!

I have updated yesterday our cs500 from 2.3.15 to In 20 minutes the update was finished

and it works like a charm in our vmware esxi 6u2 FC environment. Before update I checked the compatibility matrix.




We successfully updated from 2.3.15 to 3.5.0 last night. However, we were advised by Nimble support to upgrade NimbleOS first and then NWT (2.3.2 to 3.3) after.
