20130275679 | LOADING A PRE-FETCH CACHE USING A LOGICAL VOLUME MAPPING - Methods, apparatus and computer program products implement embodiments of the present invention that include receiving a storage command from a host computer to retrieve first data from a specific physical region of a storage device, and responsively retrieving second data from one or more additional physical regions of the storage device based on a logical mapping managed by the host computer. The second data is conveyed to a cache. In some embodiments, the logical mapping is received from the host computer prior to receiving the storage command. In alternative embodiments, the logical mapping is retrieved from the storage device prior to receiving the storage command. | 2013-10-17 |
20130275680 | STORAGE APPARATUS AND DATA MANAGEMENT METHOD - Storage area assignment is specified in accordance with control modes for the cache memory. A storage apparatus which is connected via a network to a host which issues data I/O requests comprises storage devices of a plurality of types of varying performance, and a control unit which manages each storage area provided by each of the storage devices of a plurality of types by means of storage tiers of a plurality of different types, and which assigns storage areas in predetermined units to virtual volumes from any storage tier among the storage tiers of a plurality of types in accordance with a data write request from the host, wherein, if there is an I/O request from the host, the control unit stores data corresponding to the I/O request in predetermined units in the cache memory and determines the storage tier of the storage area assigned to the virtual volume storing the data according to the mode of writing to the cache memory. | 2013-10-17 |
20130275681 | CACHING FOR HETEROGENEOUS PROCESSORS - A multi-core processor providing heterogeneous processor cores and a shared cache is presented. | 2013-10-17 |
20130275682 | APPARATUS AND METHOD FOR IMPLEMENTING A MULTI-LEVEL MEMORY HIERARCHY OVER COMMON MEMORY CHANNELS - A system and method are described for integrating a memory and storage hierarchy including a non-volatile memory tier within a computer system. In one embodiment, PCMS memory devices are used as one tier in the hierarchy, sometimes referred to as “far memory.” Higher performance memory devices such as DRAM placed in front of the far memory and are used to mask some of the performance limitations of the far memory. These higher performance memory devices are referred to as “near memory.” | 2013-10-17 |
