Update: 2025-10-19
Description
For this episode I invited our raging reporter on scene Pete Koehler! Pete is going over all the benefits, requirements, and limitations around vSAN ESA Global Deduplication. This feature was released with 9.0.1 and is available per request as discussed in this blog post. If you want to get access make sure to sign up using the form in the blog.
Just as a summary, right now vSAN ESA Global Deduplication requires:
- Version 9.0.1
- 25GbE (or higher) networking
- Telemetry needs to be enabled (CEIP)
There are a few limitations:
- Minimum of 3 hosts and maximum of 16 hosts in a cluster
- Does not support the use of Stretched Cluster functionality
- Cannot be combined with data-at-rest-encryption
