摘要： Methods and apparatuses for operating a hybrid storage aggregate are provided. In one example, such a method includes operating a first tier of physical storage of the hybrid storage aggregate as a cache for a second tier of physical storage of the hybrid storage aggregate. The first tier of physical storage includes a plurality of assigned blocks. The method also includes updating metadata of the assigned blocks in response to an event associated with at least one of the assigned blocks. The metadata includes block usage information tracking more than two possible usage states per assigned block. The method can further include processing the metadata to determine a caching characteristic of the assigned blocks.

摘要： The present invention is applicable to the field of data processing, and provides a data cache method, device, and system in a multi-node system. The method includes: dividing a cache area of a cache medium into multiple sub-areas, where each sub-area is corresponding to a node in the system; dividing each of the sub-areas into a thread cache area and a global cache area, where there is a mapping established between the thread cache area and a disk array by adopting an associative manner, and there is a mapping established between the global cache area and the disk array by adopting a set-associative mapping manner; when a process reads a file, detecting a read frequency of the file; when the read frequency of the file is greater than a first threshold and the size of the file does not exceed a second threshold, caching the file in the thread cache area; or when the read frequency of the file is greater than the first threshold and the size of the file exceeds the second threshold, caching the file in the global cache area. According to the present invention, the problem in the prior art that a single cache area cannot identify an affinity node may be effectively solved; overheads of remote access of a system are reduced, and I/O performance of the system is improved.

摘要： The present disclosure is directed to a system for dynamically adaptive caching. The system includes a storage device having a physical capacity for storing data received from a host. The system may also include a control module for receiving data from the host and compressing the data to a compressed data size. Alternatively, the data may also be compressed by the storage device. The control module may be configured for determining an amount of available space on the storage device and also determining a reclaimed space, the reclaimed space being according to a difference between the size of the data received from the host and the compressed data size. The system may also include an interface module for presenting a logical capacity to the host. The logical capacity has a variable size and may include at least a portion of the reclaimed space.

摘要： Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. Only a subset of the plurality of hierarchy levels may be loaded to memory, thereby reducing the memory “footprint” of cache metadata and expediting the process of restoring the cache metadata during startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot. Thereafter, as requests to read data items on the storage medium are processed using cache metadata to identify addresses at which the data items are stored in cache, the identified addresses may be stored in memory. When the computer is later shut down, instead of having to transfer the entirety of the cache metadata from memory to storage, only the subset of the plurality of hierarchy levels and/or the identified addresses previously loaded to memory may be transferred (e.g., to the cache device), thereby expediting the shutdown of the computer.
摘要翻译：本发明的实施例提供了用于管理提供存储介质（例如，磁盘存储）上的地址之间的映射的高速缓存元数据和存储数据项上的高速缓存设备上的相应地址的技术。在一些实施例中，高速缓存元数据可以存储在包括多个层次级别的分层数据结构中。可以仅将多个层次级别的子集加载到存储器，从而减少高速缓存元数据的存储器“占用空间”，并且在启动操作期间加快恢复高速缓存元数据的过程。通过使用缓存元数据来执行与重新启动相关的操作，可以进一步加快启动。此后，当使用高速缓存元数据来处理在存储介质上读取数据项的请求时，识别数据项被存储在高速缓存中的地址，所识别的地址可被存储在存储器中。当计算机稍后关闭时，不是必须将整个高速缓存元数据从存储器传送到存储器，所以只有先前加载到存储器的多层次级别和/或已识别地址的子集可以被传送（例如，缓存设备），从而加速计算机的关闭。
