Abstract
Instead of all the NAND memory having asynchronous independent plane read (AIPR) enabled, a system utilizes a master-SSD to route data to multiple client SSDs via a controller memory buffer (CMB) according to the underlying NAND hardware (HW) of each of the client SSDs. The master-SSD will also analyze the application data retrieval of the logical data that is to be routed. The system comprises SSDs with AIPR NAND circuitry and SSDs with non-AIPR NAND circuitry. The system further comprises the master-SSD that will route data to any of the SSDs in the system based on the data retrieval type (sequential or random). Each of the SSDs can be of a different type beyond the NAND chip, such as HW IPs or specific firmware (FW) that is tuned towards specific data routing and retrieval requirements.
