20080287243 | Reducer and method of use thereof - The reducer contains a lubricant inside, which is at least partly flowable during the operation, the inside of the reducer being tightly sealed from the outside. The reducer includes a communicating part that communicates the inside and the outside of the reducer. The communicating part is blocked with a blocking member that has oil repellency, air permeability, and non-permeability to oil. | 11-20-2008 |
20100311902 | NANOPARTICLES COMPRISING CALCIUM PHOSPHATE ETHYLENE IMINE COMPOSITIONS AND METHODS OF PRODUCTION THEREOF - Highly dispersible inorganic compound nanoparticles modified by functional molecules include the functional molecules; a high molecular nitrogen compound having at least two amino groups selected from primary amino groups, secondary amino groups and tertiary amino groups; and inorganic compound nanoparticles bonded to at least one amino group of the at least two amino groups. The high molecular nitrogen compound is modified by the functional molecules, and the inorganic compound nanoparticles are covered with the high molecular nitrogen compound modified by the functional molecules. | 12-09-2010 |
20140325121 | STORAGE SYSTEM - A storage system monitors the first access frequency of occurrence which is the access frequency of occurrence from a host device during a first period, and the second access frequency of occurrence which is the access frequency of occurrence from a host device during a second period shorter than the first period. Along with performing data relocation among the tiers (levels) in the first period cycle based on the first access frequency of occurrence, the storage system performs a decision whether or not to perform a second relocation based on the first access frequency of occurrence and the second access frequency of occurrence, synchronously with access from a host device. Here the threshold value utilized in a decision on whether or not to perform the first relocation is different from the threshold value utilized in a decision on whether or not to perform the second relocation. | 10-30-2014 |
20150127854 | COMPOUND STORAGE SYSTEM AND STORAGE CONTROL METHOD - One or more storage systems are connected to one or more storage boxes comprising multiple storage devices. Multiple storage areas provided by one or more storage boxes include an allocated area, which is a storage area that is allocated to a virtual volume, and an empty area, which is a storage area that is not allocated to any logical volume. Multiple owner rights corresponding to multiple storage areas are set in one or more storage systems. A storage system having an empty area owner right changes an empty area to the allocated area by allocating the empty area. In a case where a configuration change (a relative change in the number of storage boxes with respect to the number of storage systems) is performed, a first storage system that exists after the configuration change sets, in the first storage system, either more or fewer owner rights than the owner rights, which have been allocated to the first storage system before the configuration change. | 05-07-2015 |
20150254186 | INFORMATION PROCESSING DEVICE HAVING A PLURALITY OF TYPES OF MEMORY CACHES WITH DIFFERENT CHARACTERISTICS - An information processing apparatus comprises a plurality types of cache memories having different characteristics, decides on a type of cache memory to be used as a data cache destination based on the access characteristics of cache-target data, and caches the data in the cache memory of the decided type. | 09-10-2015 |
20150350322 | STORAGE SUBSYSTEM - The present invention provides a storage subsystem capable of realizing a backend network enabling SSDs arranged in a small number of rows to be shared among controllers, and capable of having a large number of HDDs loaded thereto, according to which the performance of the storage is enhanced. In a topology of the backend network, the respective controllers | 12-03-2015 |
20150370484 | STORAGE DEVICE AND DATA INPUT/OUTPUT METHOD - Proposed are a storage apparatus and a data input/output method capable of improving the response performance of the overall storage apparatus. When a storage controller of a storage apparatus receives a first read command that designates a plurality of storage areas in the logical volume as a read destination, the storage controller identifies the storage media and address that are actually storing the data written into the storage area, creates, for each of the storage media, a second read command that designates a part or all of each of the identified addresses in the identified storage media as a read destination and sends each of the created second read commands to the corresponding storage media, and transfers, to the host computer, the data that was read from each of the addresses designated in the second read command and sent from each of the storage media that sent the second read command. | 12-24-2015 |
20150370713 | STORAGE SYSTEM AND STORAGE CONTROL METHOD - In a storage system, first and second controllers have respective first and second buffer and cache areas. The first controller stores write data in accordance with a write request in the first cache area without involving the first buffer area and to transfer the stored write data to the second cache area without involving the second buffer area. The first controller is configured to determine which of the first and second cache areas is to be used as a copy source and to be used as a copy destination depending on whether the storing of the first write data in the first cache area had been successful or on whether the transfer of the write data from the first cache area to the second controller had been successful, and by copying data from the copy source to the copy destination, recovers data in an area related to a transfer failure. | 12-24-2015 |
