In multilayers data storages the storage drivers are grouped into separate layers according to their technical characteristics. The first layer contains high-speed solid-state drivers (SSDs), whereas the other layers can have HDDs or others storage devices (tape, optical devices). The multilayer data storage provides high speed data access and can be formed by using hardware or software solutions. In multilevel software-define storages (SDS), the separate data storage are grouped with respect to levels of their technical characteristics, the type of stored data, and availability requirements for the end user. Multilevels SDS allows for optimization of the data placement in the storage. The main node of SDS is represented by a controller. The SDS controller is a software platform (open source and other) which includes solution tools for management, monitoring and migration of data between layers.
