    Abstract: A computing system architecture that facilitates constructing a virtual disk that is customized for an application is described herein. An exemplary computing system having such architecture includes a first plurality of homogeneous storage servers, each storage server in the first plurality of storage servers comprising respective data storage devices of a first type. The exemplary computing system also includes a second plurality of homogeneous storage servers, each storage server in the second plurality of storage servers comprising respective data storage devices of a second type. A virtual disk that is customized for an application is constructed by mapping a linear (virtual) address space to portions of storage devices across the first plurality of storage servers and the second plurality of storage servers. The storage servers are accessible over a full bisection bandwidth network.

    Abstract: A method of relating the user logical block address(LBA) of a page of user data to the physical block address (PBA) where the data is stored in a RAIDed architecture reduces to size of the tables by constraining the location to which data of a plurality of LBAs may be written.

    Abstract: Virtual storage arrays consolidate data storage from branch locations at data centers. The virtual storage array appears to storage clients as a local data storage; however, the virtual storage array data is actually stored at a data center. To overcome the bandwidth and latency limitations of wide area networks between branch locations and the data center, systems and methods predict, prefetch, and cache at the branch location storage blocks that are likely to be requested in the future by storage clients. When this prediction is successful, storage block requests are fulfilled from branch locations' storage block caches. Predictions may leverage an understanding of the semantics and structure of the high-level data structures associated with the storage blocks. Prefetching agents on storage clients monitor storage requests to determine the associations between requested storage blocks and the corresponding high-level data structures as well as other attributes useful for prediction.

    Abstract: A high efficiency portable archive implements a storage system running on a virtualization layer to archive point-in-time versions of a raw data set and the storage system itself as a virtual system on archive media. The high efficiency portable archive can be implemented in a variety of computer architectures. The virtualization layer presents to the storage system a normalized representation of a set of hardware based on components of the computer architecture, shielding the storage system from the actual hardware components of the computer architecture. The storage system and point-in-time versions of the raw data set can be restored to any hardware subsystem that supports the virtual system.

    Abstract: The present invention allows distribution of load generated by a single VOL to multiple processor units, by dividing the VOL into a plurality of smaller fractions called sub-VOL and distributing their ownership to multiple processor units. The division of a VOL is performed by dividing the control information of the VOL for plurality of sub-VOLs and (A) assigning VOL ownership to a processor unit for processing the tasks that are related to complete VOL (e.g. VOL RESERVE command) and (B) assigning ownership of each sub-VOL to different processor units for processing tasks that are specific to that sub-VOL (e.g. Read/Write commands). Thus the load on a singular sub-VOL owner processor unit becomes only a fraction of the total load generated by the VOL. The present invention helps in achieving a relatively even distribution of load among processor units.

    Abstract translation: 本发明允许通过将VOL划分成称为sub-VOL的多个较小部分并将其所有权分配给多个处理器单元来将由单个VOL生成的负载分配给多个处理器单元。 通过将VOL的多个子VOL的控制信息除以(A)将VOL所有权分配给用于处理与完成VOL(例如VOL RESERVE命令)相关的任务的处理器单元和( B)将每个子VOL的所有权分配给不同的处理器单元,以处理特定于该子VOL的任务(例如,读/写命令)。 因此,单个子VOL所有者处理器单元上的负载仅仅是VOL产生的总负载的一小部分。 本发明有助于实现处理器单元之间相对均匀的负载分配。

    Abstract: A storage module may be configured to service I/O requests according to different persistence levels. The persistence level of an I/O request may relate to the storage resource(s) used to service the I/O request, the configuration of the storage resource(s), the storage mode of the resources, and so on. In some embodiments, a persistence level may relate to a cache mode of an I/O request. I/O requests pertaining to temporary or disposable data may be serviced using an ephemeral cache mode. An ephemeral cache mode may comprise storing I/O request data in cache storage without writing the data through (or back) to primary storage. Ephemeral cache data may be transferred between hosts in response to virtual machine migration.

    Abstract translation: 存储模块可以被配置为根据不同的持久性级别来服务I / O请求。 I / O请求的持久性级别可能涉及用于服务I / O请求的存储资源,存储资源的配置,资源的存储模式等。 在一些实施例中,持久性级别可以涉及I / O请求的高速缓存模式。 可以使用临时缓存模式来处理与临时或一次性数据有关的I / O请求。 短暂缓存模式可以包括在高速缓存存储器中存储I / O请求数据,而不用通过(或返回)到主存储器来写入数据。 短信缓存数据可能会在主机之间传输,以响应虚拟机迁移。

    Abstract: A system and method for migrating domains from one physical data processing system to another are provided. With the system and method, domains may be assigned direct access to physical I/O devices but in the case of migration, the I/O devices may be converted to virtual I/O devices without service interruption. At this point, the domain may be migrated without limitation. Upon completion of the migration process, the domain may be converted back to using direct physical access, if available in the new data processing system to which the domain is migrated. Alternatively, the virtualized access to the I/O devices may continue to be used until the domain is migrated back to the original data processing system. Once migration back to the original data processing system is completed, the access may be converted back to direct access with the original physical I/O devices.
