  • Publication number: 20150052397
    Abstract: According to one embodiment, when being notified of an interruption of an external electric power supply, a second processor performs a saving operation for storing management information and data stored in a first volatile memory to a first non-volatile memory, and records a progress log, indicating a progress of the saving operation, into a second volatile memory. The first processor periodically checks whether the progress log is recorded in the second volatile memory or not, and when the progress log is recorded in the second volatile memory, the first processor stores the progress log into the second non-volatile memory.

  • Patent number: 8954798
    Abstract: Embodiments of the present invention provide backup and restoration functions for a storage device of a PCI-Express (PCI-e) type that support a low-speed data processing speed for a host. Specifically, embodiments of this invention provide backup and restoration functions for one or more (i.e., a set of) semiconductor storage devices (SSDs). In general, the present invention provides an alarm unit and a secondary power supply coupled to a backup controller. The backup controller is coupled to a backup storage device. When a primary power supply is deactivated (e.g., fails), an alarm unit and the secondary power supply is activated. In response to this activation, the backup controller will backup any data stored on any SSDs of the storage system (as well as any data stored in main memory of the storage system or in main memory of any host server connected thereto).

A primary storage switch performs dynamic address translation between logical storage addresses received from host devices and physical addresses of SAN storage arrays. When power failure in the primary storage switch is detected, metadata associated with the dynamic address translation operation is sent to a secondary storage switch via a network connection to provide the dynamic address translation in lieu of the primary storage switch. A storage array experiencing power failure similarly sends cached data to another storage array via a network connection so that the other storage array can substitute the failed storage array. During the power failure, a data backup module in the primary storage switch or the storage array is powered by a temporary power source.

  • Patent number: 8700951
    Abstract: In one embodiment of the invention, a flash-based/solid-state storage system with an implemented data redundancy scheme such as RAID is configured to hold parity data in a volatile memory such as RAM and write such parity data to the non-volatile flash media when a full stripe of data has been written to the media. Other embodiments in certain situations force an early write of the parity for a partial stripe that has not been fully written to the non-volatile media. Those situations may include a data access error on data in a partial stripe and a detected power loss event with a partial stripe present. Embodiments are directed to writing additional data with the parity data for the partial stripe and then later using the additional data in data recovery. This approach allows the controller to easily detect the presence of a partial stripe and handle such a stripe accordingly.

    Abstract: A client terminal receives, in response to a boot command issued by a user to boot the client terminal, a first start command to start monitoring. The client terminal acquires first time information, repeatedly at certain time intervals from a basic software, and stores the first time information in a storage area. The client terminal receives a termination command to terminate the basic software. If the termination command is a command to terminate the basic software by using the basic software, the client terminal stores normal termination information in the storage area. When a second start command is received, and no normal termination information is stored in the storage area, the client terminal acquires second time information from the basic software and creates, depending on a result of comparison between the second time information and the first time information, log information relating to a termination of the basic software.

    Abstract: A memory controller including a detection module and a protection module is provided. The memory controller is applicable to a memory having a command transmission port and a data transmission port. The detection module detects whether an error condition occurs in an electronic device associated with the memory. When the error condition is detected, the protection module sends an interrupt command to the memory via the command transmission port to stop an operation associated with the data transmission port.

  • Patent number: 8650363
    Abstract: A memory subsystem includes a volatile memory, a nonvolatile memory, and a controller including logic to interface the volatile memory to an external system. The volatile memory is addressable for reading and writing by the external system. The memory subsystem includes a power controller with logic to detect when power from the external system to at least one of the volatile and nonvolatile memories and to the controller fails. When external system power fails, backup power is provided to at least one of the volatile and nonvolatile memories and to the controller for long enough to enable the controller to back up data from the volatile memory to the nonvolatile memory.

  • Patent number: 8639976
    Abstract: A storage area network (SAN) is provided with redundancy and recovery mechanism. A primary storage switch performs dynamic address translation between logical storage addresses received from host devices and physical addresses of SAN storage arrays. When power failure in the primary storage switch is detected, metadata associated with the dynamic address translation operation is sent to a secondary storage switch via a network connection to provide the dynamic address translation in lieu of the primary storage switch. A storage array experiencing power failure similarly sends cached data to another storage array via a network connection so that the other storage array can substitute the failed storage array. During the power failure, a data backup module in the primary storage switch or the storage array is powered by a temporary power source.

  • Patent number: 8612801
    Abstract: A server chassis includes an uninterruptible power supply, and a server including a controller. The uninterruptible power supply is configured to provide a reserve power when a primary power is lost, and to send a power loss signal when the primary power is lost. The controller is configured to receive a desired server uptime, to receive an indication that a power limit for the server is fixed or decreasing over the desired server, to receive the power loss signal from the uninterruptible power supply, to send a power capacity query to the uninterruptible power supply, to receive a reserve power capacity of the uninterruptible power supply in response to the power capacity query, to calculate the power limit for the server based on the reserve power capacity of the uninterruptible power supply and on the desired server uptime, and to enforce the power limit on the server.

  • Patent number: 8560877
    Abstract: An engine unit and a control unit are connected via an interface. A power source supplies electric power to the interface. The engine unit is controlled based on a reference clock generated in the control unit and transmitted to the engine unit via the interface. Only when a voltage output from the power source to the interface is in the operating-voltage range, the clock generator sends the reference clock to the engine unit via the interface.
