摘要： There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers and a disk subsystem, which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.

摘要： A roll bar is provided behind seats of an open car, and there is provided a wind deflector to deflect air flow coming from the vehicle rear during the open-state driving on the roll bar. The wind deflector is configured so as to have air permeability in such a manner that an air permeability rate of its upper section is greater than that of its lower section. Part of air flow passes through the wind deflector. Since the amount of the air flow passing through the lower section of the deflector directed to the neck portion is suppressed compared to the air flow passing through the upper section, both the reducing of the air flow beyond the wind deflector and the suppressing of the passenger feeling displeasure with the air flow (against the neck portion) can be attained, and thereby the passenger can be prevented effectively from feeling displeasure.
摘要翻译：在打开的汽车的座椅后面设置一个滚动条，并且在打开状态下在滚动条上行驶时设置有一个导风板，用于使来自车辆后方的气流偏转。挡风板构造成具有透气性，使得其上部的透气率大于其下部的透气率。气流的一部分通过导风板。由于与通过上部部分的空气流相比，通过导向器颈部的导流板的下部的空气流量被抑制，所以减少超过挡风板的气流和抑制乘客可以实现气流（相对于颈部）的不满，从而可以有效地防止乘客感到不适。

摘要： In multiprocessing system executing processing called NUMA prefetch, when a prefetch instruction is issued to a prefetch unit, an address converter converts an address specified by an operand of the instruction into a physical address. A prefetch type determiner determines whether the instruction is an NUMA prefetch instruction or a conventional perfect prefetch instruction. If the instruction is an NUMA prefetch instruction, an address determiner determines whether the physical address is a local address or a remote address. If the address is a local address, the processing of the prefetch instruction is terminated. If the address is a remote address, a cache tag checker checks a cache. When cache hit occurs, the processing is terminated. When cache mishit occurs, a prefetch request is issued to a main storage controller. As a result, data is prefetched from a remote main storage to a cache in a local main storage.

摘要： A method and a storage system are provided for implementing a sustained large block random write performance mechanism for shingled magnetic recording (SMR) drives in a redundant array of inexpensive disks (RAID). A Solid State Drive (SSD) is provided with the SMR drives in the RAID. The SSD is used in a hot spare mode, which is activated when a large block random-write event is identified for a SMR drive in the RAID. In the hot spare mode, the SSD temporarily receives new incoming writes for the identified SMR drive. Then the identified SMR drive is updated from the SSD to restore the state of the identified SMR drive, and operations continue with normal writing only using the SMR drives in the RAID.

摘要： A control unit of a storage system controller receives an access command to a first file specifying a first access position in the first file. A storage apparatus stores management information of the first file and management information of each of subfiles obtained by dividing the first file. The management information of the first file contains information associating a data position in the first file and management information of a subfile containning data at the data position. The management information of each of the subfiles contains information associating a data position in the corresponding subfile and a physical storage position. The control unit references the management information of the first file to identify the management information of the subfile containning the data at the first access position, and references the management information of the identified subfile to identify a physical storage position of the first access position.
