摘要:
A method for cloud computing comprising collecting cloud computing node status information from a cloud computing node connected to the cloud computing network; collecting cloud computing service status information indicative of an attribute of a cloud computing service executed in the node; collecting environmental data sets from computing systems connected to a network connected to the cloud, each environmental data set corresponding to attribute values of the computing systems; building a group of computing systems; storing the node and cloud service status information, the environmental data sets, and the identical attribute value of each computing system in a database; and responsive to a request for characteristic data from one of the computing systems, selecting the respective characteristic data out of the status information and the environmental data sets in the database and sending the characteristic data over the cloud computing network and the network to the requesting computing system.

A method of managing remote storage sets retention grace period, an archive retention period, and a backup retention period all equal to the same time period. In response to receiving a request to migrate a file to remote storage by any one of HSM, archive, or backup, the method creates a stub of the file, stores the stub in local storage, moves the file to remote storage, and backs up the file at the remote storage. In response to receiving a request to access an HSM file, the method determines if the requested file is in HSM remote storage; if so, the method returns the requested file from remote storage; if not; the method determines if the requested file is in archive remote storage or backup storage and, if so, returns the requested file from said remote storage. In response to receiving a request to access an archived file, the method determines if the requested file is in archive remote storage; if so, the method returns the requested file; if not, the method determines if the requested file is in HSM remote storage or backup remote storage and, if so, returns the requested. In response to receiving a request to access a backup file, the method determines if the requested file is in backup remote storage; if so, the method returns the requested file; if not, the method determining if the requested file is in archive remote storage or HSM remote storage and, if so, returns the requested file.
摘要:
A system and associated method for managing data. Each pointer of at least one pointer is stored in a metadata object. The pointer resides in a first repository, each unique file resides in a second repository, and the metadata object resides in third repository. Each pointer is deleted from the first repository. Upon receipt from the first repository of an event indicating both a unique file and a pointer no longer resides in the first repository, the pointer is searched for in each metadata object residing in the third repository pertaining to a hierarchical metadata management system (HMMS). After searching and locating the pointer in a metadata object in the third repository, the pointer is restored to the first repository. A hierarchical storage management system (HSM) is notified that the pointer currently resides in the first repository thus allowing the HSM to retrieve the unique file from the second repository.

A system and associated method for managing data using a hierarchical metadata management system (HMMS). First, storing each pointer of at least one pointer in a metadata object wherein said pointer resides in a first repository, each unique file resides in a second repository, and said metadata object resides in third repository. Next, deleting each pointer from the first repository. Upon receipt from the first repository of an event indicating both a unique file and a pointer no longer resides in the first repository, searching for the pointer in each metadata object residing in the third repository pertaining to a HMMS. After searching and locating the pointer in a metadata object in the third repository, restoring the pointer to the first repository. Finally, notifying a hierarchical storage management system (HSM) that the pointer currently resides in the first repository thus allowing the HSM to retrieve the unique file from the second repository.

A method for managing a mass storage system wherein the mass storage system comprises a first storage space and a second storage space. A file index is generated which lists in a uniformly distributed way each file along with a first characteristic quantity, a second characteristic quantity, and a status information, wherein the status information specifies if the file is held on the first storage space or on the second storage space. A sample of files is selected from the file index. The sample of files contains a given number of files, wherein the status information of each file of the given number of files specifies the file to be held on the first storage space. The first critical value is determined by use of the first characteristic quantity of each file comprised in the sample of files and a second critical value is determined by use of the second characteristic quantity of each file of the sample of files. Then, a first subset of files comprising each file for which the first characteristic quantity is larger than the first critical value and for which the second characteristic quantity is larger than the second critical value and which is specified by the status information to be held on the first storage device is determined.

Power consumption reduction of a mirrored RAID storage subsystems is disclosed, wherein data are mirrored to a secondary mirror disk system, the secondary mirror disk system alternates between an operational stage and a power-save stage, wherein data to be mirrored to the secondary mirror disk system is saved in a substantially always operational pre-stage storage if the secondary mirror disk system is in a power save stage and subsequently moved from the pre-stage storage to the secondary mirror disk system when the secondary mirror disk system is operational.

The invention relates to a method for adaptively assigning of a plurality of data management application instances (DM instances) building up a data management application (DM application) to a plurality of data objects (folders, files, data extents or parts of files, or other logical grouped data) organized in a tree structure, the method comprising the steps of: providing sets of separation points for each of the DM instances, each separation point defining at least one sub-section of the tree which is assigned to the corresponding DM instance to perform a data management task, storage of history data being descriptive of the data objects which have been affected by a previous data management task, determining a processing load for past data management tasks of each of the DM instances based on the history data, adapting the separation points in the tree for balancing the processing loads of the DM instances of future data management tasks.
