Abstract: A clustered network-based storage system includes a host server, multiple high availability system controller pairs, and multiple storage devices across multiple arrays. Two independent storage array subsystems each include a quorum drive copy and are each controlled by a HA pair, with remote volume mirroring links coupling the separate HA pairs. The host server includes a virtualization agent that identifies and prioritizes communication paths, and also determines capacity across all system nodes. A system storage management agent determines an overall storage profile across the system. The virtualization agent, storage management agent, quorum drive copies and remote volume mirroring link all operate to provide increased redundancy, load sharing, or both between the separate first and second arrays of storage devices.

Abstract: One or more techniques and/or systems are provided for mirroring a caching log data structure from a primary storage controller to a secondary storage controller over multiple interconnect paths. The secondary storage controller may be configured as a backup or failover storage controller for the primary storage controller in the event the primary storage controller fails. Data and/or metadata describing the data may be mirrored from the primary storage controller to the secondary storage controller over one or more interconnect paths. The caching log data structure may be parsed into a plurality of streams. The streams may be assigned to interconnect paths between the primary storage controller and the secondary storage controller. A data ordering rule is enforced during mirroring of storage information of the streams across the interconnect paths (e.g., the secondary storage controller is to receive data in the order it was sent by respective streams).

Abstract: A system and method efficiently calculates an estimated amount of storage required to split a clone volume from its parent volume. The system and method is illustratively embodied as a command line interface (CLI) command, i.e., a clone split estimate command, executed by an estimation module of a storage system. Notably, the estimation module cooperates with a file system of the storage system to quickly access data structures containing information used to perform the storage calculation without the need to access each block of the clone and parent volumes.

Abstract: An application may store data to a dataset comprising a plurality of volumes stored on a plurality of storage systems. The application may request a dataset image of the dataset, the dataset image comprising a volume image of each volume of the dataset. A dataset image manager operates with a plurality of volume image managers in parallel to produce the dataset image, each volume image manager executing on a storage system. The plurality of volume image managers respond by performing requested operations and sending responses to the dataset image manager in parallel. Each volume image manager on a storage system may manage and produce a volume image for each volume of the dataset stored to the storage system. If a volume image for any volume of the dataset fails, or a timeout period expires, a cleanup procedure is performed to delete any successful volume images.

Abstract: One or more techniques and/or systems are provided for mirror vote synchronization. For example, a first storage device is located at a first storage site, and a second storage device is located at a second storage site. The second storage device is configured according to a data mirroring configuration where data from the first storage device is mirrored to the second storage device. Mirror vote metadata is generated based upon an up-to-date state of the data mirroring configuration. The mirror vote metadata indicates whether the first storage device and/or the second storage device are up-to-date or not. The mirror vote metadata may be replicated between the first storage site and the second storage site. If the first storage site fails, then the second storage site may provide switchover operation using the second storage device based upon the mirror vote metadata.

Abstract: A high-performance device interface (HPDI) provides flexible and high-performance access by applications residing in a Virtual Machine (VM) to high-performance devices. The technique enables VM applications to use a single interface even when multiple device drivers exist, and can pass data efficiently between a VM application and a front-end device driver (a device driver implemented in a VM, such as may be used in a paravirtualization environment). It improves overall performance of a VM by reducing the copying of data during communications between a VM application and a front-end device driver, which reduces processor and memory usage.

Abstract translation: 高性能设备接口（HPDI）通过驻留在虚拟机（VM）中的应用程序向高性能设备提供灵活和高性能的访问。 该技术使VM应用程序即使在存在多个设备驱动程序时也可以使用单个接口，并且可以在VM应用程序和前端设备驱动程序（VM中实现的设备驱动程序）之间高效地传递数据，例如可用于半虚拟化 环境）。 通过减少VM应用程序和前端设备驱动程序之间的通信期间的数据复制，可以提高VM的整体性能，从而降低处理器和内存使用率。

Abstract: A hybrid media storage architecture has a log-structured file system configured to control a plurality of different storage media organized as hybrid storage media that cooperate to provide a total storage space of a storage system. The log-structured file system is configured to perform initial placement and migration of data, as well as fine-grain write allocation of the data, among storage space locations of the hybrid storage media to thereby improve the performance characteristics of the media. By defining and implementing heuristics and policies directed to, e.g., types of data, the file system may initially place data on any of the different media and thereafter migrate data between the media at fine granularity and without the need for manual enforcement.

Abstract: A method, system and program are disclosed for accelerating data storage by providing non-disruptive storage caching using clustered cache appliances with packet inspection intelligence. A cache appliance cluster that transparently monitors NFS and CIFS traffic between clients and NAS subsystems and caches files using dynamically adjustable cache policies provides low-latency access and redundancy in responding to both read and write requests for cached files, thereby improving access time to the data stored on the disk-based NAS filer (group).

Abstract: Systems and methods for providing for efficient switchover for a client in a storage network between the use of one or more a primary storage resources to one or more disaster recovery (DR) resources are provided herein. Embodiments may implement synchronization between such resources on a data plane and a control plane to allow for a transition between resources to be implemented in a manner that is minimally disruptive to a client. Moreover, embodiments may provide for processing resources which allow for switching a client between a primary storage resource to a secondary storage resource with minimal administrative interaction.
