Hi,

I consider enabling dedup in his VDI environment with persistent desktops but i would like to understand how that works. Desktops are running on ESX and are split on multiple datastores. At what level does the dedup apply or operates? For one specific datastore for all of them? what is the best/easiest way to monitor the storage gain? 

Thanks for your help

Hello,

Hope you’re well.

You can enable dedupe at a storage container level and monitor it there also.

I’d recommend taking a look at - https://portal.nutanix.com/page/documents/solutions/details/?targetId=TN-2032-Data-Efficiency%3ATN-2032-Data-Efficiency for a wider explanation of the functionality.

It would be helpful to know which AOS version you’re using and how your storage is laid out, i.e. containers etc.

Cheers,

Kim

Hi,

Thanks for the documentation.

I have one question though even i think having the answer.

If i have 2 storage containers containing VMs with same OS (Windows) where dedup is enabled.

Will the dedup operate individually only per SC or it will operate on both SC knowing redundant blocks will be found in the two SC?

Thanks in advance for your answer

Hi there,

That’s a really good question, and I’d understand logic for both answers but I’m almost 100% confident it would only operate on the configured storage container because you wouldn’t want any ‘dedupe related’ conditioning to happen outside of the desired container.

Cheers,

Correct Kim. It works only in the container.
