摘要： Caching techniques for use in a computer system comprising a core and at least one edge device. The core comprises at least one object addressable storage system. At least one cache is disposed logically between the core and the at least one edge device. The cache has a replacement policy that selects from among the content units in the cache based upon at least one replacement criterion selected from the group consisting of: an identity of a source that wrote an evaluated content unit; when the replacement is performed subsequent to a request to access at least one content unit, an identity of a requestor that issued the request; a size of an evaluated content unit; a content type of an evaluated content unit; and when metadata was written along with an evaluated content unit, the substance of the metadata.

摘要： One embodiment is a system for locating content on a storage system, in which the storage system provides a location hint to the host of where the data is physically stored, which the host can resubmit with future access requests. In another embodiment, an index that maps content addresses to physical storage locations is cached on the storage system. In yet another embodiment, intrinsic locations are used to select a storage location for newly written data based on an address of the data. In a further embodiment, units of data that are stored at approximately the same time having location index entries that are proximate in the index.

摘要： One embodiment is directed to a method in a computer system including a host computer and at least one storage system including first and second storage volumes, the host computer including at least one application program executing thereon. The method comprises acts of intercepting and redirecting an access request from the at least one application program to the first storage volume to the second storage volume. Other embodiments are directed to a computer readable medium with instructions for performing the method, a host computer with at least one controller to intercept and redirect the access request. Other aspects are directed to methods in a computer system including a host computer, a first storage system including a first storage volume, and a second storage system including a second storage volume, wherein the second storage volume is a hardware mirror of the first storage volume. One method comprises an act of servicing a read request to the second storage volume while maintaining the second storage volume as an active hardware mirror of the first storage volume. Another method comprises an act of, in response to a failure preventing access from the host computer to the first storage volume, servicing access requests directed to the first storage volume from the second storage volume without reconfiguring the host computer.

摘要： A method and system for processing a request to retrieve data from a database is disclosed. The method of the present invention comprises receiving the request which comprises a function that processes at least one data item specified in the request, retrieving the at least one data item from a database, and invoking the function. When the function is invoked, at least one parameter comprising information related to the at least one data item is passed to the function. Thus, a function can be written independently of the data which they are called to process.

摘要： One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.

摘要： Methods and apparatus for migrating a logical object. In one embodiment, a migration is performed by automatically determining the source location(s) of the logical object, moving the data stored therein to a target location while maintaining the availability of the data at the source location to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In another embodiment, a migration is performed by automatically provisioning target location(s) to store a logical object, moving the data in the logical object to the target location(s) while maintaining its availability to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In a further embodiment, a migration is performed by moving the data within a logical object from a source logical volume to a target logical volume, automatically servicing access requests from an application program at the target logical volume after moving the data, and retiring the source logical volume.
