This is a useful question for anyone managing VMware workloads on FlashSystem 9200. I'd also be interested in seeing a practical configuration workflow, especially around enabling compression and deduplication, recommended settings, and any performance considerations. Real-world examples or best practices from admins who have implemented this setup would be very helpful.

I've found that the key is to configure the FlashSystem 9200 data reduction settings at the storage pool/volume level rather than treating compression and deduplication as separate VMware features. For VMware workloads, I'd first confirm that the pool and volumes are using the appropriate data reduction settings, then present the volumes to the ESXi hosts through the recommended multipathing configuration.

Before enabling it across the whole environment, I'd suggest testing with a smaller datastore and monitoring capacity savings, CPU impact, and workload performance. Also, make sure the VMware and FlashSystem versions are supported together.

For scripting, I'd use the FlashSystem CLI to standardize pool/volume creation rather than manually configuring each datastore. IBM's Storage Virtualize CLI documentation is useful for turning the workflow into a repeatable process.
