摘要： Method and system for managing port failover in storage system comprising first storage processor and first port and second storage processor and second port. Storage system adapted to communicate with FC switch. Storage system providing first and second names characterizing first and second ports to switch for registration such that the first name associated with first port and second name associated with second port. Storage system detects the state of first and second processors. Failure state in first or second processor activates deregistration of port associated therewith. Storage system providing to switch for re-registration one of the names in response to detecting failure in processor associated with one of the ports. The one of the names provided to switch such that the one of the names characterizing the one of the ports is associated with the other of the ports.

摘要： A method is used in managing accesses to storage. An amount of data storage space in use by a mapped logical volume and RAID group characteristics of a storage pool used by the mapped logical volume are determined. Based on the amount and the RAID group characteristics, a report of storage resources corresponding to the mapped logical volume is produced. Based on the report, accesses to the mapped logical volume are controlled.

摘要： A pre-fetch method for a data storage system having disk drives and a cache memory. The method generates a history as pages are from the disk drives for storage in the cache memory, such history indicating whether a page previous to the requested page is already in the cache memory. The history generation is used during subsequent requests to determine, when a page is again requested, the number of pages that are to be read from the disk drive into the cache memory, the number of pages to be read being determined from the generated history.

摘要： A method, performed at a first storage processor (SP) connected to a mirroring second SP, includes (a) receiving a write command at the first SP from a host directed to a particular address of a data storage array, (b) identifying a reference in a first cache that is uniquely associated with the particular address, the reference having a token count field, (c) determining whether the reference is synchronized with a corresponding reference in a second cache, and (d) if the reference is synchronized with the corresponding reference, then (1) performing a cache write operation on a cache page pointed to by the reference if the reference stores a maximum token count value and (2) otherwise, sending a token request message from the first SP to the second SP over a cache mirroring bus to request a token from the second SP prior to performing the cache write operation.

摘要： Example embodiments of the present invention include a method, system and computer program product for managing spinlocks in a multi-core computer system. The method comprises providing a spinlock per core in the multi-core computer system and storing each spinlock in a respective memory location configured to be access independently by respective cores of the multi-core computer system. A request is then received at a core in the multi-core computer system to perform an operation on a spinlock in the multi-core computer system. A multi-reader/single writer spinlock is obtained in response to the request.

摘要： A storage system uses a block-level file system to manage physical storage of data blocks of logical units, the file system being mounted on an owning one of a set of storage processors. The storage processors redirect received storage requests to the owning storage processor, and periodically the amount of redirection is evaluated. If the amount of redirection is higher than a threshold, then the file system is dismounted at the owning storage processor and mounted at another storage processor to reduce the amount of redirection.
摘要翻译：存储系统使用块级文件系统来管理逻辑单元的数据块的物理存储，该文件系统被安装在一组存储处理器中的所有的一个上。存储处理器将接收的存储请求重定向到拥有的存储处理器，并且周期性地评估重定向的量。如果重定向的数量高于阈值，则文件系统在所有的存储处理器上被卸载并安装在另一个存储处理器上以减少重定向的数量。
