摘要： An apparatus and method for copying data are disclosed. A data track to be replicated using a peer-to-peer remote copy (PPRC) operation is identified. The data track is encoded in a non-transitory computer readable medium disposed in a first data storage system. At a first time, a determination of whether the data track is stored in a data cache is made. At a second time, the data track is replicated to a non-transitory computer readable medium disposed in a second data storage system. The second time is later than the first time. If the data track was stored in the data cache at the first time, a cache manager is instructed to not demote the data track from the data cache. If the data track was not stored in the data cache at the first time, the cache manager is instructed that the data track may be demoted.
摘要翻译：公开了一种用于复制数据的装置和方法。识别要使用对等远程复制（PPRC）操作来复制的数据轨道。数据轨道被编码在布置在第一数据存储系统中的非暂时计算机可读介质中。在第一时间，确定数据轨迹是否存储在数据高速缓存中。在第二时间，将数据轨道复制到布置在第二数据存储系统中的非暂时性计算机可读介质。第二次比第一次晚。如果数据轨道首次存储在数据高速缓存中，则指示高速缓存管理器不从数据高速缓存降级数据轨道。如果数据轨道在第一时间未被存储在数据高速缓存中，则指示高速缓存管理器可以降低数据轨道。

摘要： Provided are a method, system, and article of manufacture for maintaining information of a relationship of target volumes comprising logical copies of a source volume. Information is maintained on a source volume having a plurality of data units and a plurality of target volumes created at different points-in-time maintaining a logical copy of the data units in the source volume for the different points-in-time. A source downstream pointer is generated for each data unit in the source volume to point to a corresponding data unit in a first target volume. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, a first upstream pointer is generated indicating one of the source and target volumes from which the target volume data unit inherits data. For each target volume data unit whose data is maintained in the source volume or another one of the target volumes, generating a second upstream pointer indicating one of the source and target volumes having the data for the data unit.

摘要： A method for allocating space in a cache based on media I/O speed is disclosed herein. In certain embodiments, such a method may include storing, in a read cache, cache entries associated with faster-responding storage devices and cache entries associated with slower-responding storage devices. The method may further include implementing an eviction policy in the read cache. This eviction policy may include demoting, from the read cache, the cache entries of faster-responding storage devices faster than the cache entries of slower-responding storage devices, all other variables being equal. In certain embodiments, the eviction policy may further include demoting, from the read cache, cache entries having a lower read-hit ratio faster than cache entries having a higher read-hit ratio, all other variables being equal. A corresponding computer program product and apparatus are also disclosed and claimed herein.

摘要： A system and method for controlling peer-to-peer remote copy (PPRC) operations initiated from one or more host devices that desire to store data contents written to a first storage system to a second storage system over a communications link. The system enables receipt and generation of copy services commands from host devices and the determination of whether a received command pertains to a copy service over an established PPRC relationship for that particular customer to enable that customer to perform storage operations effecting data written to a first storage server having source volumes and stored in a remote second storage system having target volumes. The copy services command effecting data contents of source volumes and/or remote target volumes will be enabled if it is determined that said PPRC relationship is already established for that customer; and, prevented if the received copy services command does effect any volume not already in a copy services relationship.

摘要： Disclosed is a technique for fault isolation. A first error check is performed on a block of data in storage to determine whether the block of data was corrupted after the block of data was transferred from memory to the storage. When the first error check indicates that the block of data was corrupted, a second error check is performed using the block of data in the memory to determine whether the block of data was corrupted before being transferred from the memory. When the second error check indicates that the block of data was corrupted before being transferred from the memory, it is determined that the block of data was corrupted before being stored in the memory. When the second error check indicates that the block of data was corrupted after being transferred from the memory, it is determined that the block of data was corrupted by at least one of the memory or a formatter that performed the transfer.Additionally disclosed is a technique in which a block of data is transferred from a memory at a first control unit to a memory at a second control unit. At the first control unit, when a second error check at the second control unit indicates that the block of data was corrupted before being transferred from the memory, a third error check is performed on the block of data in memory at the first control unit. When the third error check indicates that the block of data was corrupted, it is determined that the block of data was corrupted at the first control unit. When the third error check indicates that the block of data was not corrupted, it is determined that the block of data was corrupted during transfer from the first control unit to the second control unit.
