摘要： 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.

摘要： 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.

摘要： Techniques for provisioning and decommissioning web servers in an automated manner. In one embodiment, a threshold value relating to an operational metric of a web server can be stored. The metric can be monitored as the web server receives requests. If the metric exceeds the threshold value, additional web servers can be automatically provisioned to handle a portion of the requests. If the metric falls below the threshold value, the additional web servers can be automatically decommissioned. In another embodiment, information can be logged pertaining to web server requests received over time. Based on this information and a threshold value, patterns of high/low server load can be determined and a policy can be generated identifying time intervals during which additional web servers should be provisioned (or existing web servers should be decommissioned). The policy can be used at server runtime to provision or decommission web servers at the identified intervals.

摘要： 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.
摘要翻译：本发明的实施例提供了用于优化镜像文件系统中的读取的装置和方法。该装置和方法接收用于读取盘中的目标区域的多个读请求块。该装置和方法将链接第一组中的读请求块，其中第一组中的所有读请求块都针对第一盘。然后将第一组中的读取请求块作为读取请求发送到第一个磁盘。当第一组中的每个读取请求块已经完成访问其第一个磁盘中的各自的目标区域时，从第一个磁盘生成读取的数据。因此，通过将读请求中的读请求块链接到单个磁盘，读操作期间不会在多个磁盘上执行读条带化。

摘要： 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.
