Abstract: A computer storage system includes a controller and a storage device array. The storage device array may include a first sub-array and a fast storage device sub-array. The first sub-array includes one or more first storage devices storing data. The fast storage device sub-array includes one or more fast storage devices storing a copy of the data stored in the first sub-array.

Abstract: A method and apparatus is provided for measuring and optimizing the orientation of data access of an electronic storage device according to data access characteristics. Monitoring storage access activity in an area of storage space is performed to gather data pertaining to one or more storage access characteristics. Measuring is performed of the characteristics of the storage access activity of at least two individual portions of the storage space. The portions are then combined in a manner to more judiciously utilize storage space. Depending on their homogeneity of access characteristics, the individual portions may then be left alone, merged with other similar portions, or further subdivided into sub-portions, which may be further merged, divided or left alone. At each merger or division determinations can then be made of whether the characteristics of storage access activity of one individual portion or sub-portion are similar to that of another portion according to predetermined criteria.

Abstract translation: 提供了一种用于根据数据访问特性来测量和优化电子存储设备的数据访问方向的方法和装置。 执行监视存储空间区域中的存储访问活动以收集与一个或多个存储访问特性有关的数据。 执行存储空间的至少两个单独部分的存储访问活动的特性的测量。 然后这些部分以更明智地利用存储空间的方式组合。 根据其访问特性的均匀性，各个部分然后可以被单独留下，与其它类似的部分合并，或进一步细分为子部分，子部分可以被进一步合并，分开或者单独留下。 然后，在每个合并或分割确定时，可以根据预定标准确定一个单独部分或子部分的存储访问活动的特征是否与另一部分或子部分的存储访问活动的特性相似。
