摘要： A system for minimizing downtime in an appliance-based business continuance architecture is provided. The system includes at least one primary data storage and least one primary host machine. The system includes an intercept agent to intercept primary host machine data requests, and to collect information associated with the intercepted data requests. Moreover, at least one business continuance appliance in communication with the primary host machine and in communication with a remote backup site is provided. The appliance receives information associated with the intercepted data requests from the intercept agent. In addition, a local cache is included within the business continuance appliance. The local cache maintains copies of primary data storage according to the information received. Furthermore, the remote site is provided with the intercepted data requests via the business continuance appliance, wherein the remote site maintains a backup of the primary data storage.

摘要： An apparatus, system, and method are disclosed for efficiently verifying writes. A storage module stores a plurality of data sets in a storage controller memory. A write module writes the plurality of data sets through a first write channel to a hard disk drive. A verification module verifies whether a representative data set of the plurality of data sets is successfully written to the first write channel or not. A mitigation module rewrites the plurality of data sets in response to an unsuccessful write of the representative data set.

摘要： A system and method is disclosed for maintaining, in a Storage Area Network (SAN), the consistency of a local copy of a remote file system sub-tree obtained from a remote source. Directory structure of the remote file system sub-tree is mapped to a remote container attached to the SAN and each remote object of the remote file system sub-tree is represented as a local object component of the remote container. Next, each of the local objects are labeled with attributes associated with the represented remote object, and metadata describing each of the local objects is stored in a metadata server. Also, a consistency policy is associated with each of the local objects in the remote container (wherein the policy defines conditions for checking freshness of said labeled attributes), and the local object components of remote container is updated in accordance with the consistency policy.

摘要： Network latencies are reduced by detecting a metadata access call for filesystem metadata contained in a filesystem node of remotely located filesystem. The metadata corresponding to the metadata access call is fetched when the metadata corresponding to the metadata access call is not contained in a local filesystem cache that has a hierarchical structure corresponding to a hierarchical structure of the remotely located filesystem. Metadata related to the metadata corresponding to the metadata access call from the remotely located filesystem is prefetched when the related metadata is not contained in the local filesystem cache. The metadata related to the metadata corresponding to the access call can be contained in a child node or a parent node of the node containing the metadata corresponding to the access call, or the descendants of such nodes.

摘要： Provided are a method, system and program for using multiple data structures to manage data in cache. A plurality of data structures each have entries identifying data from a first computer readable medium added to a second computer readable medium. A request is received for data in the first computer readable medium. A determination is made as to whether there is an entry for the requested data in one of the data structures. The requested data is retrieved from the first computer readable medium to store in the second computer readable medium in response to determining that there is no entry for the requested data in one of the data structures. One of the data structures is selected in response to determining that there is no entry for the requested data in one of the data structures and an entry for the retrieved data is added to the selected data structure.

摘要： Embodiments of the invention relate to automated system problem diagnosing. An index is created with problem description information of previously diagnosed problems, a diagnosis for each problem, and a solution to each diagnosis. System states, traces and logs are extracted from a source system with a new problem. The problem diagnosis system generates problem description information of the new problem from the system states, traces and logs. Problem description information of the new problem is compared with problem description information in the problem description index. A search score is computed for each document in the problem description index. The search score is a measure of similarity between each document in the index and the description of the new problem. A matching score is assigned to each previously diagnosed problems based on the search score. The matching score is a measure of similarity between the new problem and each previously diagnosed problem. The system determines a diagnosis and solution of the new problem based on a diagnosis and solution of one of the previously diagnosed problems.

摘要： A method of extending functionality of a data storage facility by adding to the primary storage system new functions using extension function subsystems is disclosed. One example of extending the functionality includes compressing and caching data in a data storage facility to improve storage and access performance of the data storage facility. A primary storage system queries a data storage extension system for availability of data tracks. If the primary storage system does not receive a response or the data tracks from the data storage extension system, it continues caching by fetching data tracks from a disk storage system. The storage extension system manages compression/decompression of data tracks in response to messages from the primary storage system. Data tracks transferred from the data storage extension system to the primary storage system are marked as stale at the data storage extension system and are made available for deletion.
