    Abstract: For disaster recovery involving a first site and a disaster recovery site, where at least a portion of management service metadata not isolated within the management service, a failover process is initiated, including creating an initial snapshot of the distributed metadata state. In a failback process, a representation is created of state changes for the management service and a delta description is calculated therefrom. The delta description is transmitted to the first site; and a reverse replica is created, at the first site, of all the workload components from the disaster recovery site. The delta description is played back to restore a distributed metadata state that existed in the disaster recovery site and to re-create it in the first site.

    Abstract: A processor includes a plurality of processing sections, each of which executes a predetermined process. A plurality of fault detecting circuits are respectively provided for the plurality of processing sections, to detect a fault in one of the plurality of processing sections as a fault processing section to generate a fault detection signal. A fault monitoring and control section controls a normal processing section as at least one of the plurality of processing sections other than the fault processing section to execute a relieving process in response to the fault detection signal. The relieving process is determined based on a process load of the fault processing section, a process load of the normal processing section, and priority levels of processes to be executed by the fault processing section and the normal processing section.

    Abstract: An improved scalable object storage system includes methods and systems allowing multiple clusters to work together. Users working with a first cluster, or with a multi-cluster gateway, can ask for services and have the request or data transparently proxied to a second cluster. This gives transparent cross-cluster replication, as well as multi-cluster compute or storage farms based upon spot availability or various provisioning policies. Vendors providing a cloud storage “frontend” can provide multiple backends simultaneously. In one embodiment, a multi-cluster gateway can have a two, three, or higher-level ring that transparently matches an incoming request with the correct cluster. In the ring, a request is first mapped to an abstract “partition” based on a consistent hash function, and then one or more constrained mappings map the partition number to an actual resource. In another embodiment, the multi-cluster gateway is a dumb gateway, and the rings are located only at the cluster level.

    Abstract: Apparatus and methods, such as those that read data from non-volatile integrated circuit memory devices, such as NAND flash. For example, disclosed techniques can be embodied in a device driver of an operating system. Errors are tracked during read operations. If sufficient errors are observed during read operations, the block is then retired when it is requested to be erased or a page of the block is to be written. One embodiment is a technique to recover data from uncorrectable errors. For example, a read mode can be changed to a more reliable read mode to attempt to recover data. One embodiment further returns data from the memory device regardless of whether the data was correctable by decoding of error correction code data or not.

    Abstract: An access control method and system and an access point. When a fault occurs in an access controller (AC), an access point (AP) configures a network-layer interface of the AP according to an Internet Protocol (IP) address and a media access control (MAC) address of the AC that are obtained by means of pre-learning, and then the AP routes a received packet to a Web server on a wireless local area network (WLAN) using the configured network-layer interface, where the packet is used by a first station (STA) to request to access an external server. Therefore, interconnection and interworking among wireless local area networks are implemented, and a breakdown of a wireless local area network caused in a centralized network architecture due to occurrence of a fault in an AC is avoided.
