摘要： A CAS data storage system with one or more source CAS data storage spaces and one or more destination CAS data storage spaces, and a communication line therebetween, receives input data at the source storage space for local storage and for replication to the destination CAS storage space. CAS metadata is used in the replication procedure between the two separate CAS storage spaces. Thus, data at the source storage space is used to form an active buffer for transfer to the destination storage space, the active buffer holding a hash result of the respective data item and a storage address. The system detects whenever there is more than one data item in said active buffer sharing a same storage address and upon such detection transfers a respective hash result of only the last of the data items.

摘要： A disk array memory system comprises: a plurality of disks in a disk array for storage of content data and parity data in stripes, content data in a same stripe sharing parity bits of said parity data, each disk having a spare disk capacity including at least some of a predefined array spare capacity, said array spare capacity providing a dynamic space reserve over said array to permit data recovery following a disk failure event; a cache for caching content data prior to writing to said disk array; and a controller configured to select a stripe currently having a largest spare stripe capacity, for a current write operation of data from said cache, thereby to write all said data of said current write operation on a same stripe, thereby to maximize sharing of parity bits per write operation and minimize separate parity write operations.

摘要： A group stamping style asynchronous replication service utilizes a loosely-accurate global clock in a data backup and recovery storage environment. The storage environment includes a set of source storage systems illustratively embodied as source replication nodes that cooperate to maintain a consistency group that may span multiple geographical sites. The storage environment also includes one or more target storage systems illustratively embodied as target replication nodes configured to service the consistency group. The group stamping style service utilizes the loosely-accurate global clock to provide consistent replication of a storage space, e.g., a target storage space, of the consistency group.

摘要： Provided are a system, program, and data structure for selecting one of multiple data paths to a device. A selection is made of one of multiple paths indicated as enabled to transmit data. A path is indicated as enabled or disabled. Transfer time data is gathered for each enabled path capable of being selected. Paths having transfer time data satisfying a threshold are indicated as disabled. Paths indicated as disabled are not capable of being selected to use to transmit data.

摘要： Disclosed is a method, system, and program for caching data. Data from a device, such as a volatile memory device or non-volatile storage device, is maintained in entries in a cache. For each entry in cache, a variable indicates both a time when the cache entry was last accessed and a frequency of accesses to the cache entry. The variable is used in determining which entry to denote from cache to make room for subsequent entries.
摘要翻译：公开了用于缓存数据的方法，系统和程序。来自诸如易失性存储器设备或非易失性存储设备的设备的数据被保存在高速缓存中的条目中。对于缓存中的每个条目，变量指示高速缓存条目最后一次访问的时间和对高速缓存条目的访问频率。该变量用于确定从高速缓存中指示的条目为后续条目腾出空间。
