    Abstract: An apparatus includes: a physical-layer device that distributes data to first lanes and performs data transfer to/from an external device by second lanes each of which has a number of the first lanes; and a transfer circuit that transfers data output by a central-processing unit performing arithmetic-processing to the physical-layer device and transfers the data received from the physical-layer device and received by the central-processing unit, the transfer circuit that comprises an information-acquisition unit that receives one of detection information of the first lanes which indicates that the physical-layer device has received data from the external device and error information of the first lanes which indicates that the data transferred to the physical-layer device from the external device has an error, from the physical-layer device, and a selection unit configured to specify the second lane to be degenerated based on one of the error information and the detection information.

    Abstract: A system, method, and machine-readable storage medium for recovering data in a distributed storage system are provided. In some embodiments, the method includes identifying a failing storage device of a first storage node having an inaccessible data segment. When it is determined that the inaccessible data segment cannot be recovered using a first data protection scheme, a first chunk of data associated with the inaccessible data segment is identified and a group associated with the first chunk of data is identified. A second chunk of data associated with the group is selectively retrieved from a second storage node such that data associated with an accessible data segment of the first storage node is not retrieved. The inaccessible data segment is recovered by recovering the first chunk of data using a second data protection scheme and the second chunk of data.

    Abstract: A remirror buffer can be used in failover situations so as to backup storage volumes in a service provider. The remirror buffer is dynamically resized to meet current usage metrics captured from a data center. A risk boundary can be defined through which resource hosts are grouped together so as to determine the usage metrics. The risk boundary can be based on a topology of the data center, such as a room/rack/sharing of power supplies, or other characteristics of the resource hosts.

    Abstract: A system and method can support transaction processing in a middleware environment. A processor, such as a remote method invocation stub in the middleware environment, can be associated with a transaction, wherein the transaction is from a first cluster. Then, the processor can handle a transactional request that is associated with the transaction, wherein the transactional request is to be sent to the first cluster. Furthermore, the processor can route the transactional request to a said cluster member in the first cluster, which is an existing participant of the transaction.

    Abstract: For passive detection of live systems during controller failover in a distributed environment, a set of member systems is sorted according to heartbeat periods used by members in the set of member systems. An amount of elapsed time since a failure of a first controller system in the distributed environment is determined. From the sorted set, a first member system is selected due to a first heartbeat period of the first member system being a shortest heartbeat period in all heartbeat periods in the sorted set of member systems. Using a processor and a memory at a second controller system, a timeout period is computed. The timeout period is an amount of time remaining in the first heartbeat period after the amount of elapsed time. The first member system is removed from the sorted set after the timeout period expires and the first member system has not sent a heartbeat.

    Abstract translation: 为了在分布式环境中的控制器故障转移期间对活动系统的被动检测，一组成员系统将根据成员系统成员中使用的心跳周期进行排序。 确定在分布式环境中的第一控制器系统故障之后所经过的时间量。 从排序集合中，由于第一成员系统的第一心跳周期是成员系统的排序集合中的所有心跳周期中的最短心跳周期，所以选择第一成员系统。 在第二个控制器系统中使用处理器和存储器，计算超时周期。 超时时间是在经过时间之后的第一个心跳周期内剩余的时间量。 超时时间到期后第一个成员系统从排序集中删除，第一个成员系统没有发送心跳。
