摘要: Cache lines are identified that provide incorrect data for read requests. The cache lines are invalidated before the incorrect data causes processing failure conditions. The cache lines providing incorrect data may be detected according to a number of the same read requests to the same cache lines. The cache lines may also be identified according to an amount of time between the same read requests to the same cache lines. The same read requests to the same cache lines may be identified according to associated start addresses and address lengths.

摘要: A hardware search structure determines the status of cache lines associated with a large disk array and at the same time reduces the amount of memory space needed for tracking the status. The search structure is configurable in hardware to different cache line sizes and different primary and secondary index sizes. A maintenance feature invalidates state record entries based both on their time stamps and on associated usage statistics.
摘要翻译: 硬件搜索结构确定与大型磁盘阵列相关联的高速缓存行的状态,并同时减少跟踪状态所需的内存空间量。 搜索结构可以在硬件中配置为不同的高速缓存行大小和不同的主索引和辅助索引大小。 维护功能使状态记录条目基于其时间戳和关联的使用统计信息无效。

摘要: A cluster of storage control members connect different clients to different storage disks. Connection path information between the different clients and disks is discovered and distributed to the storage cluster members. The connection path information is then used to maintain coherency between tiering media contained in the different storage cluster members. Unique Small Computer System Interface (SCSI) identifiers may be associated with the different connection paths to uniquely identify particular storage disks connected to the clients.
