Abstract: A storage control system is configured to obtain first data associated with a logical data device and to store the first data in a first entry of a log-structured array. The storage control system is further configured to invalidate a second entry of the log-structured array based at least in part on the storage of the first data in the first entry. The second entry comprises second data that was associated with the logical data device prior to obtaining the first data. The storage control system is further configured to determine that a first indication in a first metadata indicates that the invalidated second entry corresponds to a transaction log and to defer reclamation of the second entry based at least in part on the determination that the first indication in the first metadata indicates that the invalidated second entry corresponds to the transaction log.

Abstract: An artificial intelligence based method for improving a software testing process, according to which upon finding a bug, a set of candidate diagnoses is proposed to the tester, based on a Model-Based Diagnosis (MBD) process. A planning process is used for automatically suggesting further test steps to be performed by the tester, to identify the correct diagnosis for the developer in the form of faulty software component that caused the bug, while minimizing the tests steps performed by the tester. Additional information is provided to the MBD process, based on the outputs of the further test steps, thereby pruning incorrect candidate diagnoses. These steps are iteratively repeated while in each time, minimizing the set of candidate diagnoses, until a single diagnosis remains in the set.

Abstract: Described are a storage system and method for providing networked access to a plurality of storage devices. The storage system includes a virtualization controller coupled to a network. The virtualization controller produces a mapping of a virtual target to one or more physical storage devices on the network. The storage system also includes an initiator in communication with the virtualization controller over to the network to receive the mapping from the virtualization controller. The initiator includes a virtualization client for translating, in accordance with the mapping, a target access request directed to the virtual target by the initiator into a target access request directed to one of the physical storage devices.
