摘要： A storage controller receives a request that corresponds to an access of a track. A determination is made as to whether the track corresponds to data stored in a solid state disk. Record staging to a cache from the solid state disk is performed, in response to determining that the track corresponds to data stored in the solid state disk, wherein each track is comprised of a plurality of records.

摘要： Priority-based garbage collection utilizes attributes of data stored in the non-volatile memory array in order to improve efficiency of garbage collection and of the overall data storage system. A set of low priority data can be selectively evicted from a non-volatile memory array. This can, for example, reduce write amplification associated with garbage collection. Another set of low priority data can be regrouped or consolidated in a different region of the non-volatile memory array. In addition, flushing of data can be performed in order to enhance or optimize garbage collection. Performance and endurance can thereby be improved.

摘要： Aspects of the present disclosure disclose systems and methods for recognizing multiple and distinct references within a cache that identify or otherwise provide access to empty blocks of data. Multiple references identifying empty blocks of data are associated with a single block of empty data permanently stored in the cache. Subsequently, each time an empty block of data is added to the cache, a reference corresponding to the empty block is mapped to a generic empty block of data stored in the cache. When a reference is removed or deleted from the cache, only the reference is deleted; the single generic block of empty data continues to reside in the cache.

摘要： A hybrid drive and associated methods increase the rate at which data are transferred to a nonvolatile storage medium in the hybrid drive. By using a large nonvolatile solid state memory device as cache memory for a magnetic disk drive, a very large number of write commands can be cached and subsequently reordered and executed in an efficient manner. In addition, strategic selection and reordering of only a portion of the write commands stored in the nonvolatile solid state memory device increases efficiency of the reordering process.

摘要： Memory devices and methods facilitate handling of data received by a memory device through the use of data grouping and assignment of data validity status values to grouped data. For example, data is received and delineated into one or more data groups and a data validity status is associated with each data group. Data groups having a valid status are latched into one or more cache registers for storage in an array of memory cells wherein data groups comprising an invalid status are rejected by the one or more cache registers.

摘要： Methods, systems, and computer programs for managing storage using a solid state drive (SSD) read cache memory are presented. One method includes an operation for determining whether data corresponding to a read request is available in a SSD memory when the read request causes a miss in a memory cache. The read request is served from the SSD memory when the data is available in the SSD memory, and when the data is not available in the SSD memory, SSD memory tracking logic is invoked and the read request is served from a hard disk drive. Invoking the SSD memory tracking logic includes determining whether a fetch criteria for the data has been met, and loading the data corresponding to the read request in the SSD memory when the fetch criteria has been met. The use of the SSD as a read cache improves memory performance for random data reads.
摘要翻译：提出了使用固态驱动器（SSD）读取高速缓冲存储器来管理存储器的方法，系统和计算机程序。一种方法包括当读取请求导致存储器高速缓存中的未命中时，确定与SSD读取请求相对应的数据是否可用的操作。当SSD存储器中的数据可用时，从SSD存储器提供读取请求，并且当SSD存储器中的数据不可用时，调用SSD存储器跟踪逻辑，并从硬盘驱动器提供读取请求。调用SSD存储器跟踪逻辑包括确定是否已经满足数据的获取准则，并且当满足获取标准时将与读取请求相对应的数据加载到SSD存储器中。将SSD用作读取缓存可提高随机数据读取的内存性能。

摘要： A method for caching data on a hard disk drive. The method begins by identifying at least one track residing on the hard disk drive to devote to caching. The method continues with determining an average for each data value both residing on the hard disk drive and not residing in random access memory. The average value being the average number of times a given data value was read into memory before being the given data value was overwritten. Next the method detects a period of hard disk activity and in response to detecting, the method concludes by copying to each cache track each data value not residing in random access memory and having an average which exceeds a first threshold.
