Abstract
A data storage system has a circuit board module, a set of Serial ATA devices, and a set of Serial ATA cables connecting the circuit board module to the set of Serial ATA devices. The circuit board module includes a circuit board, multiple host circuits mounted to the circuit board and multiplexer circuitry mounted to the circuit board. Each host circuit is configured to perform data storage operations on the behalf of an external client. The multiplexer circuitry is configured to (i) receive control signals from the host circuits and (ii) provide communications pathways between the host circuits and the set of Serial ATA devices in response to the control signals. Such an embodiment alleviates the need for multiple versions of disk drive assemblies and their associated costs.
