A system and method for verifying the consistency of mirrored data sets between source and destination storage systems is provided. A destination verification module sends version information to the source storage system where the source verification module determines whether the source and destination storage systems are utilizing compatible versions of the verification module. If the destination verification module receives an acceptable version from the source, the destination module then determines a base PCPI to utilize for verification and sends a PCPI identifier of the base PCPI to the source. The source verification module generates and transmits a data stream consisting of comprising of checksum information. The destination verification module compares the received data stream with checksum information retrieved from disk. If there are mismatches, i.e. the received data differs from the data retrieved from disk, the destination verification module logs the data mismatches in a verification log file.

System and method for non-disruptive check of a mirror

An embodiment of the invention provides an apparatus and method for optimizing reads in a mirrored file system. The apparatus and method receives a plurality of read request blocks for reading the target regions in disks. The apparatus and method will chain the read request blocks in a first set, where all of the read request blocks in the first set are targeted to a first disk. The read request blocks in the first set are then sent as a read request to the first disk. When each read request block in the first set has completed accessing their respective target regions in the first disk, then the read data is generated from the first disk. Therefore, by chaining the read request blocks in a read request to a single disk, read striping is not performed across multiple disks during a read operation.

Optimizing reads for verification of a mirrored file system

A system and method verifies and repairs mirrored data sets. Verification modules executing on both the source and destination computers cooperate to identify a common persistent consistency point image (PCPI) of the source and destination data sets. Once the common image has been identified, the source sends a data stream comprising the data from the source data set to the destination to be compared with the destination data set.

System and method for verifying and correcting the consistency of mirrored data sets

A system for communicating with a mobile device is provided by aggregating content from at least one source of content having a first set of markup tags readable by executable code on the mobile device and a second set of markup tags. The aggregated content having the second set of markup tags is formatted with the first set of markup tags by either reorganizing the aggregated content, extracting irrelevant information, incorporating relevant information, combining one or more source together. A set of actions based on the formatted content is displayed using the first set of markup tags.
