Abstract: Resource management processes are implemented by a computer processor and logic executable by the computer processor. The logic is configured to calculate a performance weight for each end user of an application executing on the computer processor. The performance weight is calculated as a function of an activity level determined for each end user and a type of the application. The logic is also configured to calculate an input/output weight for each end user from a combination of an input/output requirement and the performance weight. The input/output requirement is indicative of an amount of storage resources of a multi-tiered storage system associated with anticipated activities of the end user. The logic is further configured to assign an amount of the storage resources for each end user based on the input/output weight.

Abstract: A file division and erasure code application executing in a controlling computational device generates data fragments and parity fragments of a file. Each of the generated data fragments and parity fragments are distributed in a different distributed computational device of a plurality of distributed computational devices, where distributing of a generated data fragment comprises determining whether any distributed computational device already stores a duplicate copy of the generated data fragment, and if any distributed computational device already stores the duplicate copy of the generated data fragment, placing the generated data fragment in the distributed computational device if no other data or parity fragment of the file has already been placed in the distributed computational device.

Abstract: A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to optimize data remanence over hybrid disk clusters using various storage technologies, determine one or more data storage technologies accessible by a file system, and determine secure delete rules for each of the one or more storage technologies accessible by the file system. The secure delete rules include a number of overwrites required for data to be securely deleted from each of the one or more storage technologies. The programming instructions are further operable to provide the secure delete rules to the file system upon a request for deletion of data for each of the one or more storage technologies a specific amount of times germane to secure delete data from the one or more storage technologies.
