    • A method and apparatus for providing hardware aware logical volume mirrors are provided. In particular, the an improved logical volume system and method are provided in which a mirroring device driver is provided that selects a physical storage device from which data is to be read based on information obtained regarding the physical devices used in the mirror of the data. The mirroring device driver may be part of a logical volume device driver (LVDD), such that a modified LVDD is provided, or may work in concert with the logical volume device driver to achieve the purposes of the present invention. The information regarding the physical devices used in the mirror may include characteristic data of physical storage devices (e.g., whether a write cache is used, whether a read-ahead cache is used, RPM speed, connector type, etc.) and may also include operational history data. One or more rules are applied to this information to determine which physical storage device is an optimum storage device from which data is to be accessed.
    • 提供了一种用于提供硬件感知逻辑卷反射镜的方法和装置。 特别地,提供了一种改进的逻辑卷系统和方法,其中提供了一种镜像设备驱动器,其根据在数据镜中使用的物理设备获得的信息来选择要从中读取数据的物理存储设备。 镜像设备驱动器可以是逻辑卷设备驱动器(LVDD)的一部分,使得提供修改的LVDD,或者可以与逻辑卷设备驱动程序一起工作以实现本发明的目的。 关于反射镜中使用的物理设备的信息可以包括物理存储设备的特征数据(例如,是否使用写高速缓存,是否使用预读高速缓存,RPM速度,连接器类型等),还可以包括 操作历史数据。 一个或多个规则被应用于该信息以确定哪个物理存储设备是要从其访问数据的最佳存储设备。
