I have a 5 nodes cluster with 6TB of Data, I'm in the process of migrating Persitent Desktops from NetApp to Nutanix Storage, I have a group of Developers that requesting 300 GB drive space each for their session, we are talking about 10 +, 3.5 TB . Now I have other users on that same cluster as well. Thus far performace is good with the migrated users, I just don't want to add the additional workload in the environment, over allocate my storage, pretty much rely on the deduplication

Questions?

would you recommend deduplication for Developpers VDI sessions?

let's say we have a hickup on the storage side, and we need to power on all the machines?

What is recommended best practices to enable deduplication, do we have a best practices guide?

In this case you will see the most benefit in both space savings and performance from Compression rather then dedup as there is only a few desktops (and that workload will likely compress very well, giving you more space in the hot tier). Also make sure to use VAAI Clones (ESXi) or Nutanix Fast Clones (Hyper-V) and thin provisioning to reduce the space they take up. As for your other questions:

No, you won't need to power on all the machines if you have a storage hiccup with dedupe enabled. The VMs don't rely on each other with dedup, we just only store 1 copy of duplicated data.

As for best practices, this will be updated for 4.5 likely as things will change, but check out https://portal.nutanix.com/#/page/docs/details?targetId=Web_Console_Guide-NOS_v3_5:sto_dedup_recommend_c.html
