Methods and systems for coupling multiple initiators to SATA storage devices

摘要

An interposer (port selector) and associated systems and methods coupling an SATA storage device to multiple, concurrently operable, storage controllers (multiple initiators). The interposer allows automatic selection of one of a plurality of a storage controllers for active coupling to the corresponding storage device. Features of the interposer and its operation detect automatically which storage controller presently requires coupling to the device and, transparently with respect to both the storage controllers and a storage device, effectuate the desired coupling.
