Title: The Innovations of Jason A Unrein
Introduction
Jason A Unrein is a notable inventor based in Wichita, Kansas. He has made significant contributions to the field of technology, particularly in the area of Serial Attached Small Computer System Interface (SAS) topologies. With a total of seven patents to his name, Unrein's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is focused on device abstracted zone management of SAS topologies. This patent outlines systems and methods that provide zone management for devices within a SAS topology. In this embodiment, a zone management device stores a zone map that identifies an initial zone of a device in the topology. The management device detects changes in the topology and identifies the current zone of the device after the change. It compares the zone map for the device to the current zone to identify any changes and generates a message for an expander in the topology based on this change. The management device then transmits the message to the expander to restore the zone of the device to its initial state.
Another significant patent involves devices with asymmetric SAS generation support. This patent describes methods and structures for devices that implement multiple versions of the SAS protocol. An exemplary embodiment includes a SAS device that has at least one physical link (PHY) supporting a specified generation of SAS protocols, along with another PHY that supports a different generation. The SAS device also features an Input/Output (I/O) processor that selects a PHY to service a SAS connection based on the supported generation of SAS protocols.
