Abstract: A controller-implemented method, according to one embodiment, includes: receiving, by a first controller, data. Metadata associated with the data is stored, by the first controller, in a specified system memory location. Second metadata received from a second controller is also stored, by the first controller, in the specified system memory location, thereby creating combined metadata. In response to the second controller entering a failed state: snapshots of the combined metadata are stored, by the first controller, to resilient storage at a predefined interval. Moreover, additional data continues to be received by the first controller. Metadata associated with the additional data is stored, by the first controller, in the specified system memory location, while changes to the metadata which occur between the snapshots of the combined metadata are also stored by the first controller. According to some approaches, the changes to the metadata are stored in a log structured array.

Abstract: Methods, systems, and apparatuses related to detecting and reporting failures for a memory device are described. When a count of bit-flip errors is above a fail threshold, a memory device can report a failure. Failure reports can indicate a rate at which the memory device is accumulating errors. An offset fail threshold may be applied instead of a default fail threshold, such as a standardized or specified threshold. The offset fail threshold can be a summation of the default fail threshold and an offset determined from an initial error count determined before the memory device has accumulated errors from use.

Abstract: A method, system and computer program product for providing early diagnosis of hardware, software or configuration problems in a data warehouse system. A received query is parsed to determine the properties of the query. The query may then be joined to existing groups of queries if those groups have shared properties of the query. After executing the query according to an execution plan, results from the execution of the query is received, which may include problem(s) that occurred during execution of the query. For those problems that reach a pre-defined threshold of becoming a “group problem” in those groups joined by the query, the problem is reported to the end user concerning those groups where the problem exceeds the pre-defined threshold. In this manner, an early diagnosis of the problems in the data warehouse system that can cause delay and failure of the processing of queries is able to occur.

Abstract: Techniques involve: in response to a number of errors of an error type in a storage disk increasing, determining an adjustment rate for a health value of the storage disk based on a total usage time length of the storage disk, where a longer total usage time length corresponds to a higher adjustment rate, and the health value indicates a health condition of the storage disk with respect to the error type. The techniques further involve increasing the adjustment rate based on a total input/output (I/O) number of the storage disk, where a greater total number of I/Os corresponds to a greater increment. The techniques further involve adjusting the health value with the adjustment rate. Such techniques can improve the accuracy of evaluating the health condition of the storage disk.

Abstract: Embodiments of the present invention provide a system for increasing intra-application efficiency by way of distributed failover. Embodiments of the invention allow data centers within an application to perform error recovery of failed transactions by shifting the processing load to another data center in the network without data redundancy amongst the data centers within the application. Avoiding the duplication of data within the data centers greatly reduces the amount of computing resources required to perform recovery and maintain service uptime, including, but not limited to, processing power, memory space, storage space, cache space, electric power, networking bandwidth, and I/O calls.
