Continuing series of VMware ESX update to build number tracking.


As always, it's a simple bit of info, often hard to find.




ESXi 4.1 = Build 260247 - Released 13 July 2010
ESXi 4.1 Update 1 = Build 348481 - Released 10 February 2011
ESXi 4.1 Update 2 = Build 502767 - Released 27 October 2011
ESXi 4.1 Update 3 = Build 800380 - Released 30 August 2012


Yes that's right ESX 4.1 has a LOWER build number than ESX 4.0 update 2!

An easy way to find build number from ESX console (i.e. without having to log into the VI Client) is to run:

vmware -v

For ESX 4.0, see VMware ESX 4.0 Update to Build Number
For ESX 3.5, see VMware ESX 3.5 Update to Build Number
