If a surplus device is removed from the initial set, forming a depleted set, the logical addresses of the surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained. | 2012-04-12 |
20120089803 | CACHE INDEX COLORING FOR VIRTUAL-ADDRESS DYNAMIC ALLOCATORS - A method for managing a memory, including obtaining a number of indices and a cache line size of a cache memory, computing a cache page size by multiplying the number of indices by the cache line size, calculating a greatest common denominator (GCD) of the cache page size and a first size class, incrementing, in response to the GCD of the cache page size and the first size class exceeding the cache line size, the first size class to generate an updated first size class, calculating a GCD of the cache page size and the updated first size class, creating, in response to the GCD of the cache page size and the updated first size class being less than the cache line size, a first superblock in the memory including a first plurality of blocks of the updated first size class, and creating a second superblock in the memory. | 2012-04-12 |
20120089804 | VOLUME ALLOCATING METHOD FOR VIRTUAL COMPUTERS AND COMPUTER SYSTEM USING THE METHOD - Allocation of virtual disk volumes of a size designated by the computer manager to a virtual computer and accessibility from the virtual computer to the virtual disk volumes without requiring intervention by a hypervisor are to be achieved. In a computer, at least one virtual computer to be in execution on the computer, and a computer system in which the virtual computer has volumes for holding data, a virtualization mechanism has a virtual volume allocating unit and a virtual volume information supplying unit, and the virtual computer has a virtual volume driver for converting positional information on virtual volumes. Additionally, the virtualization mechanism holds the virtual volume information together with defining information for the virtual computer to which the virtual volumes have been allocated. | 2012-04-12 |
20120089805 | MEMORY STORAGE DEVICE, MEMORY CONTROLLER THEREOF, AND METHOD FOR AUTOMATICALLY CREATING FILL-FILE THEREOF - A memory storage device, a memory controller thereof, and a method for automatically creating a fill-file thereof are provided. In the present method, a plurality of logical addresses is configured and grouped into a plurality of logical blocks to be mapped to physical blocks of a memory chip in the memory storage device. When a host system is powered on, whether the logical addresses have been formatted into a partition is determined. If the logical addresses have been formatted into a partition, whether a fill-file of a predetermined file capacity exists is determined. If the fill-file does not exist, data related to the fill-file is respectively filled into a file allocation table (FAT) and a root directory of the formatted partition when the host system reads the FAT and the root directory, so as to automatically create the fill-file. | 2012-04-12 |
20120089806 | REGION MANAGEMENT APPARATUS, REGION MANAGEMENT METHOD, AND PROGRAM - To provide a technology that, regardless of the capacity of a storage device, enables its areas to be flexibly partitioned and managed, and, when a file is allocated to a region also, can also use its areas effectively by means of an efficient method. When a region size of a storage device is expressed as the sum of mutually differing power-of-2 values, and areas whose size is one of the power-of-2 sizes configuring that sum are taken to be master partitions, to partition the areas into partitions each of whose size is the size made by successively dividing each master partition in half and to generate an allocation table holding allocation information expressing the allocation status of each of the files that have partitions with each of the sizes included in the master partitions. To manage a region based on the allocation information stored in the allocation table. | 2012-04-12 |
