摘要： A system having input/output hot spot tracking is disclosed. The storage system includes a storage device, a host controller coupled to the storage device, and a tracking engine coupled to the host controller and the storage device. The host controller is configured to managed input/output of the storage device. The tracking engine includes a storage map cycling between active status and passive status. Input/output commands are stored in the storage map during the active status. Like input/output commands in the storage map during active status are counted and compared to a number. Counts greater than the number are reported as input/output hot spots.

摘要： A storage system is disclosed including storage devices configured to store data, and a logical storage volume coupled to the storage devices and configured to store a subset of the data as segments. The storage system also includes a controller including a cache and memory. The memory is configured to include records such that each record corresponds with a segment in the logical storage volume and each record includes information regarding data stored in the corresponding segment. The controller is configured to access the records in response to a cache miss of the cache to determine if requested data from the cache miss is stored and ready for access in the logical storage volume. The controller is also configured to update the subset of data stored in the segments as a function of cache misses.
摘要翻译：公开了一种存储系统，包括被配置为存储数据的存储设备，以及耦合到存储设备并被配置为将数据的子集存储为段的逻辑存储卷。存储系统还包括具有缓存和存储器的控制器。存储器被配置为包括记录，使得每个记录对应于逻辑存储卷中的段，并且每个记录包括关于存储在相应段中的数据的信息。控制器被配置为响应于缓存的高速缓存未命中来访问记录，以确定来自高速缓存未命中的请求数据是否被存储并准备好在逻辑存储卷中进行访问。控制器还被配置为根据高速缓存未命中来更新存储在段中的数据子集。
