VMAX3-AFA and Workload Type

With an All Flash VMAX3, how important or what difference, if any, does it make to select a specific SLO and workload type on a LUN.

For example: DSS vs OLTP.

My initial thought is that in a Hybrid array, it has some value.

In an AFA, I should get the same performance and latency regardless of that SLO. Unless it introduces some kind of QoS or similar.

Any engineering docs detailing the differences would be helpful. The product guide does not offer much detail.

Also curious about compression vs n compression and it's impact on LUN performance.

Thanks,
