Redundant array of independent discs and dispersed storage network system re-director
Systems and method for accessing data in a storage network include a processing module receives redundant array of independent disks (RAID) data to store determining which memories to utilize (e.g., a RAID memory, local and/or remote dispersed storage network (DSN) memory) based on one or more of the metadata, the RAID data, a vault lookup, a command, a message, a performance indicator, a predetermination, local DSN memory capabilities, remote DSN memory capabilities, RAID memory capabilities, and a comparison of requirements to capabilities of the RAID memory and local and/or DSN memory. The processing module saves the determination choice in a memory indicator that is stored in one or more of the RAID memory, the local DSN memory, the remote DSN memory, and a DSN user vault.
