Abstract: A method for protecting data in a storage system is disclosed. In one embodiment, such a method includes detecting, by a first hardware management console, first battery-on status associated with a first uninterruptible power supply. The method further detects, by a second hardware management console, second battery-on status associated with a second uninterruptible power supply. The method communicates, from the first hardware management console to the second hardware management console, the first battery-on status. The method then triggers, by the second hardware management console, a dump of modified data from memory to more persistent storage upon detecting both the first battery-on status and the second battery-on status. A corresponding system and computer program product are also disclosed.

Abstract: A method for reducing incidents of data loss in redundant arrays of independent disks (RAIDs) having the same RAID level is disclosed. In one embodiment, such a method identifies, in a data storage environment, a set of RAIDs having a common RAID level.

Abstract: A method for reporting incidents of data loss in a storage environment comprising redundant arrays of independent disks (RAIDs) is disclosed. In one embodiment, such a method monitors storage drive failures in a storage environment. For a storage drive failure detected in the storage environment, the method reports the RAID type in which the storage drive failure occurred and whether data loss occurred in the RAID as a result of the storage drive failure. In certain embodiments, the method reports whether the data loss could have been prevented had the RAID type been converted to a more robust RAID type. In other or the same embodiments, the method reports whether the data loss was prevented by the RAID type. A corresponding system and computer program product are also disclosed.

A trap storage unit is configured for data in the storage and the trap storage unit is indicated as a trap. Storage units are configured for data in the storage that are not indicated as a trap. A request is received to access the trap storage unit from a process executing in a host system. Notification is returned to the host system that the process requesting to access the trap storage unit is a potentially malicious process.

Abstract: A machine learning module receives inputs comprising attributes of a storage controller, where the attributes affect failures that occur in the storage controller. In response to a failure occurring in the storage controller, a plurality of output values corresponding to a plurality of recovery mechanisms to recover from the failure in the storage controller are generated via forward propagation through a plurality of layers of the machine learning module. A margin of error is calculated based on comparing the generated output values to expected output values corresponding to the plurality of recovery mechanisms, where the expected output values are generated from an indication of a correct recovery mechanism for the failure. An adjustment is made of weights of links that interconnect nodes of the plurality of layers via back propagation to reduce the margin of error, to improve a determination of a recovery mechanism for the failure.

Abstract: A method to dynamically switch between data transfer techniques includes receiving an I/O request and computing a cost of executing the I/O request using a memory copy data transfer technique. The memory copy data transfer technique copies cache segments associated with the I/O request from cache memory to a permanently mapped memory, which is permanently mapped to a bus address window. The method also computes a cost of executing the I/O request using a memory mapping data transfer technique. The memory mapping data transfer technique temporarily maps cache segments associated with the I/O request from the cache memory to the bus address window. The method uses one of the memory copy data transfer technique and the memory mapping data transfer technique to transfer cache segments associated with the I/O request, depending on which one is less costly. A corresponding system and computer program product are also disclosed.

Abstract: A peer to peer remote copy operation is performed between a primary storage controller and a secondary storage controller, to establish a peer to peer remote copy relationship between a primary storage volume and a secondary storage volume. Subsequent to indicating completion of the peer to peer remote copy operation to a host, a determination is made as to whether the primary storage volume and the secondary storage volume have identical data, by performing operations of staging data of the primary storage volume from auxiliary storage of the primary storage controller to local storage of the primary storage controller, and transmitting the data of the primary storage volume that is staged, to the secondary storage controller for comparison with data of the secondary storage volume stored in an auxiliary storage of the secondary storage controller.

Abstract: Provided are techniques for concurrent Input/Output (I/O) enclosure firmware/Field-Programmable Gate Array (FPGA) update in a multi-node environment. First notifications are sent to each I/O enclosure management engine on each of a plurality of server nodes that code activation for a first set of I/O enclosures is starting. An update image is distributed to the first set of I/O enclosures. The update image on the first set of I/O enclosures is activated by sending an activate reset command to each of the first set of I/O enclosures, wherein a reset is not propagated to other devices within each I/O enclosure in the first set of I/O enclosures in response to determining that the reset is an activate reset. In response to the activate reset command completing, second notifications are sent to each I/O enclosure management engine that code activation for the first set of I/O enclosures has completed.

Abstract: A method to dynamically optimize utilization of data transfer techniques includes processing multiple I/O requests using one of several data transfer techniques depending on which data transfer technique is more efficient. The data transfer techniques include: a memory copy data transfer technique that copies cache segments associated with an I/O request from a cache memory to a permanently mapped memory; and a memory mapping data transfer technique that temporarily maps cache segments associated with an I/O request. In order to process the I/O requests, the method utilizes a first number of “copy” windows associated with the memory copy data transfer technique, and a second number of “mapping” windows associated with the memory mapping data transfer technique. The method dynamically adjusts one or more of the first number and the second number to optimize the processing of the I/O requests. A corresponding system and computer program product are also disclosed.

Abstract: A method for converting a redundant array of independent disks (RAID) to a more robust RAID level is disclosed. Such a method identifies, in a data storage environment, higher risk storage drives having a failure risk above a first threshold. The method determines a number of the higher risk storage drives that are contained within a RAID array of the data storage environment. The method determines whether the number exceeds a second threshold. The method also determines whether a destage rate associated with the RAID array is below a third threshold. In the event the number exceeds the second threshold and the destage rate is below the third threshold, the method converts the RAID array to a more robust RAID level. A corresponding system and computer program product are also disclosed.
