Abstract: A storage device may include a data storage portion, including a plurality of blocks of data, and a controller. The controller may be configured to receive a command that includes an inherent trim request for the plurality of blocks of data. The controller may be configured to perform a trim operation on a first set of trim blocks from the plurality of blocks of data, which may include fewer than all blocks of the plurality of blocks of data and may include trim blocks on which the controller can complete the trim operation within a predetermined time. The controller may be configured to update a pending trim table to include an indication of a second set of trim blocks on which trim is to be performed, which may include blocks of data on which the controller cannot complete the trim operation within the predetermined time.

Abstract: A method, apparatus, and program product access memory resources of a computer using a group of direct access memory (DMA) devices. A first DMA device is designated a primary device after association with an active translation table (ATT), while a second DMA device is designated a backup device after association with an inactive translation table (ITT). A translation is entered into the ATT for the first DMA device to permit it to perform a DMA operation, while a translation is inhibited from being entered into the ITT for a second DMA device to prevent it from performing a DMA operation. Thereafter, the roles of the first and second DMA devices may be swapped by associating the first DMA device with the ITT and associating the second DMA device with the ATT. The computer may be a logically partitioned computer of the type that includes a plurality of logical partitions.

Abstract: A method and apparatus are provided for mapping multiple address spaces into a single bus, such as a single peripheral component interconnect (PCI) bus. The single bus is coupled to a first processor complex and a second processor complex. An original address of a memory access is shifted to a unique address space for each originator/target of an operation. The shifted address is used on the single bus. Then the shifted address is shifted back to the original address for completing the operation on a destination bus. The original address of a memory access is shifted to a unique address space for each originator/target of an operation using a respective predefined value (+X1, +X2, or +X3) for shifting the original address above a predefined boundary for each originator/target of the operation.
