Patent number: 9904486Abstract: 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.Type: GrantFiled: July 17, 2014Date of Patent: February 27, 2018Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9019708Abstract: Apparatus and systems for improved access to storage devices from the sides of sleds mounted in storage enclosures. Embodiments provide apparatus and systems for a sled in a storage enclosure that provides access to storage devices on either side of the sled when the sled is slid forward out of its enclosure. Multiple sleds may be enclosed within a single enclosure to permit access to a portion of the storage devices in the enclosure hence reducing the problems of instability of the rack if the enclosure is mounted near the top of the rack.Type: GrantFiled: August 25, 2011Date of Patent: April 28, 2015Assignee: LSI CorporationInventors: Macen Shinsato, Mohamad H.

Patent number: 9021141Abstract: 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.Type: GrantFiled: December 11, 2013Date of Patent: April 28, 2015Assignee: LSI CorporationInventors: Mohamad El-Batal, Anant Baderdinni, Mark Ish, Jason M.

Publication number: 20150019795Abstract: An apparatus configured to shadow volatile data while minimizing read latency is described. In an implementation, the apparatus includes a memory controller configured to operatively couple to a volatile memory device and a non-volatile memory device. The volatile memory device includes a volatile memory cell and the non-volatile memory device includes a corresponding non-volatile memory cell. The volatile memory device has a first transfer speed and the non-volatile memory device has a second transfer speed. The memory controller is configured to cause storage of data to the volatile memory cell and the non-volatile memory cell and to determine an occurrence of an unanticipated power outage. The memory controller is configured set a read speed to the second transfer speed and to cause replication of the data from the non-volatile memory cell to a corresponding volatile memory cell upon recovery from the unanticipated power outage.Type: ApplicationFiled: October 1, 2013Publication date: January 15, 2015Applicant: LSI CorporationInventors: Justin R.

Publication number: 20110231674Abstract: 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.Type: ApplicationFiled: December 11, 2008Publication date: September 22, 2011Inventors: Jason M.
