摘要： A storage manager application implemented in a first computational device maintains a virtual logical volume having a plurality of segments created by the storage manager application, wherein space is reserved at the end of a physical volume corresponding to the virtual logical volume, and wherein the physical volume comprises a linear storage medium. A request is received to write data, at the first computational device, from a second computational device. The data is written to the reserved space, wherein the writing of the data causes new segments to be created in the reserved space.

摘要： The provision of verification for data storage cartridges having data storage tape media employs determining the volume identity of a data storage cartridge; and providing an internal label at each block of data to be written to the data storage tape media of the data storage cartridge, the internal label at least comprising the volume identity. Verification of a label comprises reading an external label of the cartridge, the external label at least comprising a volume identity of the cartridge; determining whether the tape media comprises valid data arranged in blocks; positioning the tape media at one of the data blocks and attempting to read an internal label from the data block; and if so, determining whether the volume identity of the external label matches the volume identity of the internal label, and, if so, determining that the matching volume identity is the volume identity of the cartridge.

摘要： An apparatus, system, and method are disclosed for recalling a logical volume from a mountable media for use in a virtual tape server. The apparatus includes a receiving module, a queuing module, and an optimizer module. The receiving module receives recall requests for logical volumes stored in a mountable media such as a tape cartridge. The queuing module places the requests in a queue to be processed in turn. The optimizer module reorders the queue based on one or more optimization rules in order to process the recall requests more efficiently.

摘要： Upgrades are made to the available capacity of cache disk storage without adding drawer(s) or blade(s) when the upgrade is requested. A cache control is configured to respond to a requested capacity upgrade, establishing a capacity restriction applicable to a filesystem providing active perceived available capacity spanning the disk drive subunits, such as drawers, blades or disk drives. The active perceived available data storage capacity and unused capacity of the filesystem are spread across the disk drive subunits. The capacity restriction is related to the requested upgrade adjustment, and the capacity restriction controls rates of data transfer with respect to the filesystem. The capacity restriction may comprise a freespace threshold for throttling of a fill rate of resident data pending premigration from the cache disk storage filesystem, and a premigration threshold for increasing drain rate of premigration data from the cache disk storage filesystem.
摘要翻译：在请求升级时，不需要添加抽屉或刀片，升级缓存磁盘存储的可用容量。高速缓存控制被配置为响应所请求的容量升级，建立适用于提供横跨磁盘驱动器子单元（例如抽屉，刀片或磁盘驱动器）的主动感知可用容量的文件系统的容量限制。主动感知的可用数据存储容量和文件系统的未使用容量分布在磁盘驱动器子单元上。容量限制与所请求的升级调整有关，容量限制控制文件系统的数据传输速率。容量限制可以包括用于限制待缓存磁盘存储文件系统的预迁移的驻留数据的填充率的自由空间阈值，以及用于增加来自高速缓存磁盘存储文件系统的预迁移数据的排出速率的预迁移阈值。

摘要： A system is provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased.
