> Currently we can configure only one SSD location while using SSD cache in LLAP. This highly undermines the capacity of some machines to use its disk capacity to the fullest. For example *AWS* provides *r5d.4x large* series which comes with *2 * 300 GB NVme SSD disk* with the current design only one of the mounted *NVme SSD* disk can be used for caching. Hence adding support for caching data at multiple ssd mounted locations.
