摘要： A system is provided to support dynamically changeable virtual mapping schemes in a data processing system. The present invention separates processing of data unit requirements from the selection of which storage subsystems to use for storage by using a storage methodologies inventory. A stored data management subsystem contains one or more hosts. A plurality of data storage elements is functionally coupled to the one or more hosts. The plurality of data storage elements is organized using a plurality of layers of mapping tables. The plurality of layers of mapping tables provides unique identification of location of the data such that individual data entries in a mapping table is variable and self-defining with respect to the amount of data managed.

摘要： A virtual stored data management system is provided. In one embodiment, the management system includes one or more hosts and a plurality of data storage elements functionally coupled to the hosts. Each data storage element includes a host network attachment, data transfer means, a storage controller, and permanent data storage media. The permanent data storage media is organized with management information uniquely associated with units of the data such that the management information may be manipulated in several different locations within the management system substantially simultaneously. Thus, the organization of the management processes allows for the management information to be processed, used, changed, or modified in several different locations within the management system at any particular instance. Provision is made for the internal processes to discover the current location of the processing, for the location to be changed as directed, and for the processing to be kept consistent when done in more than one place simultaneously.

摘要： An apparatus and a method for improving the fault tolerance of storage systems by replacing disk drives, which are about to fail, are disclosed. The set of disk drives in a storage system are monitored to identify failing disk drives. A processing unit identifies the failing disk drive and selects a spare disk drive to replace the failing disk drive. The selected spare disk drive is powered on, and data from the failing disk drive is copied to the selected spare disk drive. A memory unit stores attributes and sensor data for the disk drives in the storage system. The attributes and sensor data are used by the processing unit to identify a failing disk drive. Attributes for disk drives are obtained by using SMART, and sensor data is obtained from environmental sensors such as temperature and vibration sensors.
