US Patent:

20110231674, Sep 22, 2011
Filed:

Dec 11, 2008
Appl. No.:

12/523509
Inventors:

Jason M. Stuhlsatz - Dacula GA, US
Mohamad El-Batal - Westminster CO, US
Keith Holt - Wichita KS, US
International Classification:

G06F 1/26
G06F 11/16
US Classification:

713300, 714 62, 714E11062
Abstract:

Disclosed is a storage system enclosure. A midplane receives, from a controller coupled to the midplane, a first drive status signal and a second drive status signal. The first drive status signal and the second drive status signal are associated with a storage device. The first drive status signal indicates a fault condition associated with the storage device. The second drive status signal indicates that an action is allowed on the storage device. A drive power control supplies or removes power from the storage device in response to the state of the first drive status signal and the second drive status signal.

Jason Stuhlsatz - Dacula GA, US
International Classification:

G06F 13/16
G06F 13/40
G06F 13/42
Abstract:

Embodiments presented herein provide for hot swappable connections to various storage devices. In one embodiment, a storage controller includes an interface operable to connect to at least one of a storage device and a midplane connected to a plurality of Non Volatile Memory Express (NVMe) storage devices. The storage controller also includes a processor operable to detect when the interface is connected to the mid-plane, to determine that the NVMe storage devices each have a x4 NVMe connection, and to communicate sideband signaling, including a reference clock, to the NVMe storage devices through the midplane via Inter-Integrated Circuit (I2C) upon determining that the NVMe storage devices each have a x4 NVMe connection.

US Patent:

20150058533, Feb 26, 2015
Filed:

Dec 11, 2013
Appl. No.:

14/103679
Inventors:

- San Jose CA, US
Anant Baderdinni - Lawrenceville GA, US
Mark Ish - Sandy Springs GA, US
Jason M. Stuhlsatz - Dacula GA, US
Assignee:

LSI Corporation - San Jose CA
International Classification:

G06F 12/02
US Classification:

711103
Abstract:

A data storage controller exposes information stored in a locally managed volatile memory store to a host system. The locally managed volatile memory store is mapped to a corresponding portion of a peripheral component interconnect express (PCIe) compliant memory space managed by the host system. Backup logic in the data storage controller responds to a power event detected at the interface between the data storage controller and the host system by copying the contents of the volatile memory store to a non-volatile memory store on the data storage controller. Restore logic restores a data storage controller state by copying the contents of the non-volatile memory store to the locally managed volatile memory store upon the application of power such that the data in the volatile memory store is persistent even in the event of a loss of power to the host system and or the data storage controller.

International Classification:

G06F 1/26
US Classification:

713300
Abstract:

Methods and structure for selectively powering a storage device over a data network. An exemplary system includes a power module configured to detect power from a host system via a network port. The system also includes an input/output controller configured to receive power derived from the network port of the power module, and in response, to identify a disk drive for a read/write operation based on information from the host system. With power derived from the network port, the power module is further configured to supply power to an expander that connects the disk drive to the input/output controller, and to supply power to the disk drive to perform the read/write operation.
