I was wondering if one could daisy chain multiple VMware Update Manager Download Service (UMDS) appliances. The documentation doesn’t say a word about it. The only thing I found Googling this was one blog that say’s it can’t be done. But that blog was from 2014, now, 2018, let’s see…
Download Vmware For Mac
Download application launcher for drive for mac. I started with a Ubuntu 16.04 LTS server and used William Lam’s script to install the UMDS on top. It needed some more config:
Automating the installation of VUM Update Manager Download Service (UMDS) for Linux in vSphere 6.5 by William Lam 10 Comments One of the most highly requested feature from customers with regards to the adoption of the vCenter Server Appliance (VCSA) is to have vSphere Update Manager (VUM) available as a Virtual Appliance. Subsequently, it downloads all new patches and notifications released after the previous UMDS download. (Optional) If you have already downloaded upgrades, patches, and notifications and want to download them again, you can include the start and end times to restrict the data to download. The installation of vSphere Update Manager Download Service (UMDS) is a simple enough process (Installed in 5.5 from the vCenter Server CD, open the folder ‘umds’, and run ‘VMware-UMDS’) and follow the prompts. Moa tunes 1.4 free download for mac.
(I tested this in Fusion virtual machines using vSphere 6.5 Update 1 (5969303))
Open the console of the first UMDS
Using a SSH (Windows: PuTTY / Mac: Termius) client, connect to the UMDS:
In the SSH session:
(In the example above I’ve added the HPE VibsDepot, to see if non-firstparty updates will get downloaded.)
It will now start downloading… It may take some time to complete, at the time of writing it was about 65 GB

Vmware For Mac El Capitan
Per William Lam’s suggestion for this test I used Python’s builtin webserver:
Using this as a foreground task, it shows all HTTP requests being received:
But first I needed to build a second UMDS, mostly the same as above, except:
- I didn’t add the HPE VibsDepot
- I pointed hostupdate.vmware.com and vapp-updates.vmware.com in the hosts file to localhost, by editing the hosts file to prevent it to try to download anything directly from VMware.com’s website.
- For some reason it is not possible to remove these entries from UMDS’s config.
- Nor to remove the updates for older versions. I didn’t need updates for any ESXi prior to 6.5.
- Instead of the HPE VibsDepot, I added the first UMDS as source:
- Start the download task:
After downloading was complete, I added the second UMDS to vCenter Update Manager:
Mac Os In Vmware
After clicking download now, the Non VMware Patches are visible in vCenter:
So it seams to be possible to daisy chain UMDS. I have no idea about the supportability of this configuration, and if using something in production, use a real webserver!
