    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： Addressed is a system and method for remote data caching and replication by local copy maintenance of remote data within a SAN file system. Distributed Storage Tank (DST), an extension to a SAN file system, provides for transparent SAN client access of local copies by importing, exporting, and storing data using network file access protocols as well as by providing assurance of metadata and file content validity. A Remote Access Agent (RAA) handles protocol implementation and conversion necessary for communication with remote data sources. Controlled by a consistency policy, consistency is maintained by RAA fetching and updating local copies if modifications have occurred to a file since it was first stored as a local copy in local storage. Additionally, RAA returns metadata pertaining to the requested data. A SAN client obtains metadata corresponding to the requested data and utilizes it to directly access locally stored copies of remote data.

    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： 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.
