Abstract: An asset health monitoring system (AHMS) can assign a confidence indicator to some or all the monitored computing asset in a data center, such as computing systems or networking devices. In response to drops in the confidence indicators, the AHMS can automatically initiate testing of computing assets in order to raise confidence that the asset will perform correctly. Further, the AHMS can automatically initiate remediation procedures for computing assets that fail the confidence testing. By automatically triggering testing of assets and/or remediation procedures, the AHMS can increase reliability for the data center by preemptively identifying problems.

Abstract: A method is described for transmitting signals in a mobile communication system which splits an information block into a plurality of split-information blocks and performs a hybrid automatic repeat request (HARQ) process upon each of the split-information blocks. A method is also described for reducing control information overhead by transmitting control information only through one control channel when splitting an information block and transmitting split-information blocks through a plurality of subframes or a plurality of resource blocks. The segmentation of the information block is performed in a physical layer to reduce medium access control (MAC) overhead and to simplify implementation.

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).

Abstract: A method and a storage server for backing up data, involves mass storage devices of users of the service that connect to the storage server of the service provider over a public data network. The customers store the data with their terminals. The data is stored to the file system of the mass storage device which encrypts the stored data and transfers the data in encrypted form over the public data network to the storage server. The storage server calculates error correction data from the encrypted data. The error correction data is stored in the mass memory of the storage server. When recovering the stored data of the users, the storage server requests the stored data of all the users whose data was used for the error correction data calculation over the public data network to be used for the recovery calculation.

Abstract: A method, system, and medium are disclosed for performing transparent failover in a cluster server system. The cluster includes a plurality of servers. In servicing a client request, a primary server replicates session data for the client into memory space of one or more backup servers. The primary server sends a response to the client, wherein the response includes an indication of the one or more backup servers. When the client sends a subsequent request, it includes an indication of the backup servers. If the primary server is unavailable, the cluster determines a recovery server from among the backup servers indicated by the request. The chosen recovery server would then service the request.

Abstract: A method for managing communications to add a first Remote Direct Memory Access (RDMA) link between a TCP server and a TCP client, where the first RDMA link references first remote memory buffer (RMB) and a second RMB, and further based on a first remote direct memory access network interface card (RNIC) associated with the TCP server and a second RNIC associated with the TCP client.

The system detects a failure in the second RDMA link. The system reconfigures the first RDMA link to carry at least one TCP packet of a session formerly assigned to the second RDMA link, responsive to detecting the failure. The system communicates at least one packet of the at least one session on the first RDMA link.

The expected behavior is updated based on an indication of whether the actual behavior is abnormal from a user.

Abstract: A computational geometry technique is utilized to detect, diagnose, and/or mitigate fault detection during the execution of a software application. Runtime measurements are collected and processed to generate a geometric enclosure that represents the normal, non-failing, operating space of the application being monitored. When collected runtime measurements are classified as being inside or on the perimeter of the geometric enclosure, the application is considered to be in a normal, non-failing, state. When collected runtime measurements are classified as being outside of the geometric enclosure, the application is considered to be in an anomalous, failing, state. In an example embodiment, the geometric enclosure is a convex hull generated in N-dimensional Euclidean space. Appropriate action (e.g., restart the software, turn off access to a network port) can be taken depending on where the measurement values lie in the space.

Abstract: A software module capable of simultaneously supporting multiple services provides log message throttling for each service with a separate “per service” log message buffer. When the software module is a device driver, for example, each device controlled by the device driver is allocated a message buffer to store descriptive log messages. Upon generation of a warning log message, descriptive log messages in the message buffer are flushed to a log file for review by an administrator. Furthermore, log message throttling may be implemented by only flushing the message buffer upon certain occurrences of warning log messages, such as in accordance with an exponential back-off algorithm.
