Abstract: A method and system for improving memory storage and threat detection is provided. The method includes requesting and authorizing permission for executing analysis code for determining if a service device is in compliance with general data protection regulations. In response, executable code is uploaded to the database hardware controller and a first database and a second database is analyzed with respect to patterns associated with the general data protection regulations. Associated results code is generated and transmitted the service device. The results code is executed with respect to the first database and the second database resulting in a storage space increase in the first database and the second database thereby improving operational functions of the first database and the second database.

Abstract: A method for detecting software installed on a computer may be provided. The method may comprise obtaining a default user identifier, collecting an installed user identifier, performing an identifier comparison by comparing the installed user identifier with the default user identifier and determining whether an installed user identifier matches a default user identifier, assigning a probability value based on the identifier comparison, performing a threshold comparison of the probability value to the a predetermined threshold value, determining whether the probability value exceeds the threshold value, and in response to determining that the probability value exceeds the threshold value, concluding that the software has been installed on the computer system.

Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: (a) obtaining grooming operation scheduling data specifying a schedule of grooming operations performed by at least first and second layers of the plurality of layers; (b) identifying, using data of grooming operation scheduling data, at least one gap in the execution of scheduled operations performed by the storage system; (c) moving an execution time of one or more grooming operation of the grooming operations into said at least one gap; and (d) repeating steps (a) to (c) to adapt to a changing usage pattern of said storage system.

Abstract: A storage controller is provided with an optical circuit switch (OCS) for managing active-passive backend storage arrays. For this purpose a system includes a host computer system, a backend storage array having a first controller and a second controller, an optical circuit switch (OCS) connected between the host computer system and the first and second controllers, and a storage system controller comprising a failover detector to detect a failover of the first controller when the first controller is in an active state and the second controller is in a passive state, and an OCS controller to control the OCS to switch connection of the host computer system from the first controller to the second controller based on the failover detector detecting a failover of the first controller to place the second controller in an active state.

Abstract: A computing device includes an interface configured to interface and communicate with a communication system, a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory that is configured to execute the operational instructions to perform various operations. The computing device determines to de-stage information stored in a cache memory to a nonvolatile memory device. The computing device determines whether the de-stage is based on a power interruption and when the de-stage is not based on a power interruption the computing device updates access counters associated with the information and the target location for the information in the nonvolatile memory, updates a data access tracking module and initiates a data relocation function to transfer the information to the nonvolatile memory device.
