US07310715B2 Method, apparatus, and computer program product for using an array of high performance storage drives included in a storage array to reduce accessing of an array of lower performance storage drives included in the storage array 失效
用于使用包括在存储阵列中的高性能存储驱动器阵列的方法，装置和计算机程序产品，以减少存储阵列中包括的低性能存储驱动器阵列的访问

Method, apparatus, and computer program product for using an array of high performance storage drives included in a storage array to reduce accessing of an array of lower performance storage drives included in the storage array
Abstract:
A method, apparatus, and computer program product are disclosed for controlling accesses of drives in a storage subsystem. A first array of a first type of drive is provided. The first type of drive is a server class of drive. A second array of a second type of drive is provided. The second type of drive is a PC class drive. The first and second arrays are bound together to form a single array of drives. The single array of drives is presented to a host that is coupled to the storage subsystem as a single array. The host is unaware that the single array includes two different types of drives. Data is stored in the second array of drives. Data is migrated from the second array of drives to the first array of drives when an access rate of the second array of drives exceeds a threshold access rate for the second type of drive.
Abstract(Chinese):

公开了一种用于控制存储子系统中的驱动器的访问的方法，装置和计算机程序产品。 提供第一类驱动器的第一阵列。 驱动器的第一种类型是驱动器的服务器类。 提供第二类驱动器的第二阵列。 第二种类型的驱动器是PC类驱动器。 第一和第二阵列绑定在一起以形成单个驱动器阵列。 将单个驱动器阵列呈现给作为单个阵列耦合到存储子系统的主机。 主机不知道单个阵列包含两种不同类型的驱动器。 数据存储在第二个驱动器阵列中。 当第二驱动器阵列的访问速率超过第二类驱动器的阈值访问速率时，数据从第二驱动器阵列迁移到第一驱动器阵列。
