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： Access to content addressable data on a network is facilitated using digital information storing devices or data repositories (“silos”) that monitor broadcast data requests over the network. A number of silos automatically monitor both data requests and data itself that are broadcast over a network. The silos selectively store data. Each silo responds to data requests broadcast over the network with data the silo has previously intercepted. A content addressable file scheme is used to enable the data repositories to reliably identify data being requested. When a data request is received, each silo evaluates whether it has all or a portion of the data being requested and responds to requests when it has the data. Requests for data are implemented by broadcasting a cryptographic has data identifier of the data file needed. The data identifier is used by a silo to determine which data to receive and store.

摘要： One embodiment is directed to a method for use in a computer system comprising at least first and second computers, wherein the first provides content addressable storage. A request to access a unit of data stored by the first computer is issued by the second computer and received by the first. In one embodiment, the unit of data comprises a first identifier identifying at least one digital asset and metadata relating to the at least one digital asset, and the request identifies the unit of data via a second identifier based, at least in part, on the content of the unit of data. In another embodiment, a request to access a unit of data is sent from a second computer and received at a first computer and identifies the unit of data via a content identifier based, at least in part, on the content of the unit of data. The content identifier is the only identifier that can be used in communication between the first and second computers to identify the unit of data.

摘要： Techniques for managing the storing of a digital asset by a first computer in a computer system that further comprises a second computer. The first computer receives a communication from the second computer including the digital asset, determines whether the digital asset has been stored by the first computer, and when it has not, stores a copy of the digital asset. The digital asset is identified by a first identifier based, at least in part, on its content. In one embodiment, the first identifier is the only identifier that can be used to identify the digital asset in communication between the first and second computers. In another embodiment, the computer system further stores a unit of data comprising the first identifier and metadata relating to the digital asset.

摘要： In one aspect, two ways of accessing a content unit stored on a CAS are provided, wherein the content unit has a content address that is computed based, at least in part, on at least a portion of its content. A first interface is provided to a file system in which the content unit is logically stored as a logical unit identified by a logical identifier, wherein the content unit is accessed in response to a request to the first interface to access the logical unit and identifying the content unit via the logical identifier. A second interface is provided through which the content unit can be accessed via the content address, wherein the content unit is accessed in response to a request to the second interface to access the content unit and identifying the content unit by the content address.

Requests for data are implemented by broadcasting a cryptographic hash data identifier of the data file needed. The data identifier is used by a silo to determine which data to receive and store. A silo includes a network interface, a digital asset collector, an asset request list, asset storage, an asset identifier processor and an asset supplier. The asset identifier processor computes a cryptographic hash asset identifier for a received asset and compares it to an asset identifier on its asset request list to verify it has the correct asset. A hash of a list of assets is also computed and broadcast over the network. When the hash of the list of assets is received by a silo, it places all the assets in its asset request list.

摘要： Representing a number of assets on an originating computer begins with selecting the assets to be represented. Cryptographic hash asset identifiers are generated; each of the asset identifiers is computed using the contents of a particular asset. The asset identifier is a content-based or content-addressable asset name for the asset and is location independent. An asset list is generated that includes the asset identifiers computed from the assets. A cryptographic hash asset list identifier is generated that is computed from the asset list. The asset list identifier is stored for later retrieval. The amen selected are also stored for safekeeping either locally or on a computer network. In the event of loss of the files from the originating computer, the asset list identifier is retrieved. Using the asset list identifier, the original asset list is found and retrieved from its safe location.

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 (OAS) system that stores a plurality of content units and provides an interface that enables content units to be accessed via object identifiers. The at least one edge device is configured to access at least some of the content units. At least one cache is configured to be disposed logically between the core and the at least one edge device and to temporarily store a subset of the content units. The at least one cache is further configured to have a limit on a maximum number of content units that can be stored on the at least one cache simultaneously.

At least one cache is disposed logically between the core and the at least one edge device. The cache has a prefetch policy that selects from among the content units based upon at least one prefetch criterion selected from the group consisting of: a source that wrote an evaluated content unit; a size of an evaluated content unit; a content type of an evaluated content unit; when the prefetch is performed subsequent to a request to access at least one of the plurality of content units, an identity of the requestor; when the prefetch is performed subsequent to a request to access at least one of the content units stored at a first time, proximity of a time at which an evaluated content unit was stored relative to the first time; and metadata written with the evaluated content unit.
