A system, method and program product for maintaining fleet performance for a fleet of platforms, especially for a fleet of aircraft. Part removal data is contained in a maintenance database. A query is constructed for extracting part removal data from the maintenance database. Weibull analysis is applied to extracted part removal data. Exposed aircraft with parts being likely to fail within a given time period are identified from the Weibull analysis results. Overall part failure numbers are generated for each failing part. Inventory is checked to determine if sufficient spares are available to repair all expected failures. Any shortfalls may be covered. A risk report is generated for the fleet and for inventory. Each risk report highlights likely problems that may require immediate attention.

A query-based spares management technique enables a storage operating system of a storage system to select disks to be added to one or more RAID groups of a volume. The spares management technique includes an attributes-based disk selection procedure that is performed by the storage operating system in response to an operator-initiated request to add disks to the volume or in response to a demand-driven request resulting from a requirement imposed by the system to add disks to the volume. The disks that are added to the RAID groups of the volume are retrieved from one or more spare pools of disks maintained by the storage system.

A controller monitors access frequencies of address ranges mapped to a data storage array. Based on the monitoring, the controller identifies frequently accessed ones of the address ranges that have lower associated wear, for example, those that are read more often than written. In response to the identifying, the controller initiates copying of a dataset associated with the identified address ranges from the data storage array to a spare storage device while refraining from copying other data from the data storage array onto the spare storage device. The controller directs read input/output operations (IOPs) targeting the identified address ranges to be serviced by access to the spare storage device. In response to a failure of a failed storage device among the plurality of primary storage devices, the controller rebuilds contents of the failed storage device on the spare storage device in place of the dataset associated with the identified address ranges.

Certain ones of a plurality of SAS hard disk drives are assigned to different SAS zones using a SAS zoning expander(s). A processor and SAS RAID controller have access to only those SAS hard disk drives assigned to the same zone(s) as the processor and SAS RAID controller. Each SAS RAID controller determines when a RAID hard disk drive in its zone fails, and then notifies the RAID hard disk drive failure to a service enclosure processor (SEP) of the SAS zoning expander. The SEP re-allocates an available hot-spare hard disk drive to the zone of the failed RAID hard disk drive. When the SAS RAID controller detects that a functional hard disk drive is now available in its zone, the RAID image is rebuilt using the zone reassigned hot-spare hard disk drive that then becomes one of the RAID hard disk drives of that zone.
