Abstract: At least one embodiment involves a method of operating a storage front-end manager system to perform pipeline planning for a low latency storage system. The method can include: receiving a write request including payload data; storing the payload data of the write request in a staging area of the storage front-end manager system; determining a transformation pipeline based at least partly on an attribute of the write request; queuing the transformation pipeline for execution on the payload data to generate data fragments for storage; and transmitting the data fragments to a plurality of multiple-data-storage-devices enclosures after the transformation pipeline is executed.

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: 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: 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.

Abstract: A system and method for data replication is described. A destination storage system receives a message from a source storage system as part of a replication process. The message includes an identity of a first file, information about where the first file is stored in the source storage system, a name of a first data being used by the first file and stored at a first location of the source storage system, and a fingerprint of the first data. The destination storage system determines that a mapping database is unavailable or inaccurate, and accesses a fingerprint database using the fingerprint of the first data received with the message to determine whether data stored in the destination storage system has a fingerprint identical to the fingerprint of the first data.
