Just a quick correction...
The last sentence should read "If you fall below the minimum GNA will cease and you will only have metadata acceleration within Node Pools".

In One FS version 6.5 the absolute minimum required was 0.5% of the cluster capacity be SSD; 2% was the recommended value. In OneFS 7.0, the absolute minimum SSD capacity was raised to 1.5% of cluster capacity. The official recommendation is still 2%. Note that you must also have 20% or more of the cluster nodes equipped with SSDs. If you fall below the minimum GNA will cease and you will only have metadata acceleration.
