ABSTRACT:
In general, the invention is directed to techniques of scalable replication of data in persistent or volatile data storage devices. In particular, a computing device comprises a host acting as a device host for a data storage device and a plurality of data storage devices capable of persistent storage of data. A data storage replication component in the computing device acts as a data storage device. This data storage replication component comprises a device interface and a plurality of host interfaces. Each of the host interfaces acts as a device host for one or more data storage devices in the plurality of data storage devices. The primary data storage replication component may cause instructions (e.g., read, write, and control instructions) and data received from the host to be replicated on each data storage device in the plurality of data storage devices.
