Abstract: As disclosed herein a computer-implemented method includes providing a plurality of resource allocation zones corresponding to a plurality of resource preparation operations, receiving a request from a requester for a resource, determining a selected resource allocation zone for a tenant from the plurality of resource allocation zones, and determining a resource usage pattern from historical usage data corresponding to the tenant. The method further includes provisioning the requested resource from the selected resource allocation zone based on the resource usage pattern, executing a resource preparation operation corresponding to the selected resource allocation zone in conjunction with provisioning the requested resource, and providing the requested resource to the tenant. A computer program product and a computer system corresponding to the above method are also disclosed herein.

Abstract: A method, computer system, and a computer program product for pre-caching resources within a cloud system is provided. The present invention may include enabling auditing. The present invention may also include following Cloud Auditing Data Federation standards. The present invention may then include determining one or more workflow patterns and resource utilizations. The present invention may then include predicting one or more resources. The present invention may lastly include caching the one or more predicted resources.

Abstract: Physical storage devices are configured as a redundant array of independent disks (RAID). As such, storage space of the physical storage devices is allocated to the RAID, and each physical storage device is part of the RAID. Where a portion of the storage space of the physical storage devices is not allocated to the RAID, this portion of the storage space is configured so that it is usable and is not wasted.

Abstract: Embodiments of the present invention provide systems, methods, and computer program products for optimizing a placement plan. In one embodiment, a method is disclosed in which a request for registration with an external advisor is received. A time to live is received from each external advisor and used to determine an overall timeout period value for a placement engine. After receiving a predictive failure alert, internal and external advisors are ranked according to criteria and advice is received from the qualified advisors. A placement plan is generated based on the advice received from the advisors.

As such, storage space of the physical storage devices is allocated to the RAID, and each physical storage device is part of the RAID. Where a portion of the storage space of the physical storage devices is not allocated to the RAID, this portion of the storage space from a mixed drive capacity is configured so that it is usable and is not wasted.

Abstract: A method and apparatus are provided for maintaining cache coherency of object management data in a computer system. The computer system is configured with a bit mask to represent changes in object management data. All changes in an object are reflected by setting an associated bit in the bit mask. A cache update of object management data is limited to the bit(s) set in the bit mask.

Abstract: A hierarchical packaging model of self-describing plugin modules and packages of plugin modules. Identifiers are assigned to each package of plugin modules in a hierarchical relationship so that adjacently identified packages are backward compatible. The package identifiers are maintained internally to the package. Similarly, identifying data of a plugin module is maintained internally within the namespace of the respective module. Interdependency of plugin modules is determined by comparison of data maintained in the namespace of each module.
