摘要： A method and apparatus for handling multi-volume datasets in a tape storage system are disclosed. In response to a write request for a multi-volume dataset, the information of the multi-volume dataset are captured by intercepting and deciphering a set of volume mount commands. Otherwise, the information of the multi-volume dataset are captured by snooping header information from a previous volume listed in a header of the multi-volume dataset. A chain of logical volume names that belongs to the multi-volume dataset is then built. Finally, the chain of logical volume names is then stored in a chain database.

摘要： A method to write information to one or more information storage media disposed in a data storage and retrieval system comprising host adapters capable of data compression and information storage devices capable of data compression. The method establishes a storage medium usage threshold and determines the actual storage media usage level for the data storage and retrieval system. The method then determines if the actual storage media usage level is greater than the storage medium usage threshold. If the actual storage media usage level is greater than said storage medium usage threshold, then the method enables use of information storage device data compression. Alternatively, if the actual storage media usage level is not greater than said storage medium usage threshold, then the method disables use of information storage device data compression.

摘要： An apparatus, system, and method are disclosed for selecting a source cluster in a distributed storage configuration. A measurement module measures system factors for a plurality of clusters over a plurality of instances. The clusters are in communication over a network and each cluster comprises at least one tape volume cache. A smoothing module applies a smoothing function to the system factors, wherein recent instances have higher weights. A lifespan module calculates a mount-to-dismount lifespan for each cluster from the smoothed system factors. A selection module selects a source cluster for accessing an instance of a specified volume in response to the mount-to-dismount lifespans and a user policy.

摘要： A method to write information to two virtual tape servers. The method writes a file to a virtual host device disposed in a first virtual tape server, where the virtual host device comprises an adjustable bandwidth. The method queues a job to copy the file to a second virtual tape server, determines the age of the copy job, and copies that file to the second virtual tape server. The method sets an age threshold, and determines if the copy job age is greater than that age threshold. If the copy job age is greater than the age threshold, then the method decreases the adjustable bandwidth, if not, the method restores the adjustable bandwidth.

摘要： A method to write information to two geographically separated virtual tape servers, where the method provides a file to a virtual tape controller, writes that file to a first virtual tape server, and queues a copy job for the file in the virtual tape controller. Subsequently, the method provides the file to a second virtual tape server. The method sets a throughput threshold, determines the actual VTC throughput, and determines if the actual VTC throughput exceeds the throughput threshold. The method sets an age threshold and determines if the copy job age is greater than that age threshold. If the actual VTC throughput is greater than the throughput threshold and the copy job age is greater than the age threshold, then the method decreases the first adjustable host bandwidth and/or the second adjustable host bandwidth, otherwise the method restores the bandwidth to a nominal value.

摘要： A system and method for guaranteeing overwrite of expired data in a media device, the data being organized according to logical units provided on media devices organized as physical volumes. The method comprises the steps of: maintaining information associated with a status of a physical volume, and updating a physical volume's status information based upon a combination of that volume's prior status and that volume's current status; specifying a time duration that expired logical unit data may remain on a physical volume; based upon the volume's updated status information, determining whether a selected volume has expired data longer than the specified time duration; and, overwriting contents of the volume having data that has expired longer than the specified time duration.

Such a system and method manage first level storage to accommodate two or more host processing systems by maintaining adequate free space in the cache for each host and by preventing one host, such as a mainframe, from taking over free space from another host, such as a Linux system.

摘要： A media server (e.g., a virtual tape server) implements a method for a dynamic media format conversion of physical volumes stored within a media library (e.g., a tape library). The method involves a recall of volume data in a media format f as stored in one or more source physical volumes of a source media, and an automatic premigration of the recalled volume data in a media format f to one or more target physical volumes of a target media. The media format f is different in one or more aspects from the media format f.
摘要翻译：媒体服务器（例如，虚拟磁带服务器）实现用于存储在媒体库（例如磁带库）内的物理卷的动态媒体格式转换的方法。该方法涉及以存储在源媒体的一个或多个源物理卷中的媒体格式f的卷数据的调用，以及以媒体格式f将被调用的卷数据自动预迁移到一个或多个目标物理卷目标媒体。媒体格式f在媒体格式f的一个或多个方面是不同的。
